 Biophilic Design: Creating a Healthy Environment

biophilic design

Biophilic design accelerates the healing process of patients.

“In every walk with nature one receives far more than one seeks!”

By Linn Smith

February 18, 2018——-Growing up in rural America I was always connected to nature. I knew from an early age that I could find peace somewhere out of doors, sometimes laying back on my saddleless horse pondering the clouds or walking the farm fields with my dog. Peace in nature was always close at hand. John Muir said it best, “In every walk with nature one receives far more than one seeks!” Biophilic design recognizes this.

What is Biophilic Design

Biophilic is derived from the term, “biophilia,” meaning “the urge to affiliate with other forms of life.” 

Biophilic design in architecture creates environmentally friendly, energy-efficient buildings and developments by effectively managing natural resources. It recognizes the human need to be close to nature by replicating it in architectural design. It seeks a healthier, happier way of life through creating sustainable buildings and cities.

“Passive biophilic architecture produces buildings that use less energy to operate because they feature efficient designs, materials and systems. The majority of biophilic architectures have highly competent heating, cooling, ventilation, lighting systems, and appliances. In addition, these biophilic restructures are built of energy-efficient materials. Green building elements contribute to a better microclimate through evaporation, filtering of dust from the air and reducing the temperatures at the rooftop,” as stated in the article “Towards a New Potential of Healthy Architecture”

Examples of Biophilic Design

The impact of these designs? Studies show that Biophilic designs have a positive effect on our health and well being. Also, using sustainable materials in the construction of biophilic designed buildings has a positive effect on our environment. Biiphilic design provides another example of creating a healthier planet for future generations.

Jostein Gaarder on Climate Change

“Human activity is draining resources and destroying natural habitats.”

By Linn Smith

February 6, 2018—–Besides being a successful author, Jotstein Gaarder works to support both human rights and a sustainable environment. Gaarder clearly states our current world condition concerning the cause and effect of climate change in the following article, which is the foreword to his 20th addition of Sophie’s World. Sophie’s World is a novel he wrote in 1995 which became a best seller around the world. 

This exerpt is from the article, “Sophie’s World in Danger: Living as though everything centres on our time is just as naïve as thinking the Earth is flat” from

“Two decades ago, a history of philosophy by an unknown Norwegian teacher became a most unlikely phenomenon. But how has time changed the writer? And how might he change his book now, if he could? Jostein Gaarder takes up his own story. However, by far the most important philosophical question of our time must be this: how are we going to save our civilization and the basis of our existence?

From time to time I am asked a question. If I had written Sophie’s World today, is there something important I would have added? Is there something I would have placed more emphasis on? The answer is a resounding yes! If I were to write a philosophical novel today, I would have focused a lot more on how we treat our planet.

It is strange to look back after only 20 years and realize that Sophie’s World doesn’t really address this question. The reason may be that over the course of these 20 years we have gained an entirely new awareness of climate change and the importance of biological diversity. An all-important principle in the study of ethics has been the golden rule, otherwise known as the reciprocity principle: do to others what you would like them to do to you. Over time, we have learnt to apply this rule more widely. In the Sixties and Seventies, people came to realize that the reciprocity principle must apply across national borders, both to the north and to the south.

But the golden rule can no longer just apply across space. We have begun to realize that the reciprocity principle applies across time, too: do to the next generation what you would like them to have done to you, had they lived on the planet before us.

It’s that simple. Love thy neighbor as thyself. Obviously, this rule must apply to the next generation and to everyone who lives on the planet after us. They are human beings, too. Therefore, we should not leave behind a planet which is less valuable than the one we have enjoyed. A planet with fewer fish in the sea. Less drinking water. Less food. Fewer rainforests. Fewer coral reefs. Fewer species of animals and plants… Less beauty. Less wonder. Less splendor and happiness.

Jostein Gaarder

Climate change and responsibility

The 20th century has taught us that people need conventions and obligations which go beyond national boundaries. 

The question we are left with at the beginning of the 21st century is: for how long can we claim human rights without accepting they come with fundamental obligations. The time is ripe for a Universal Declaration of Human Obligations. It no longer makes sense to think about an individual’s rights and freedoms without also thinking about the responsibility of individuals and individual states – not least our responsibility to safeguard the rights of future generations.

At this very moment we are experiencing the consequences of man-made climate change. They are dramatic. However, opinion polls indicate that the people of this world are not particularly concerned. One day in the future, global-warming denial may be considered one of the greatest conspiracies of all time.
The era we live in is exceptional in every way. On one hand, we belong to a triumphant generation, which can explore the universe and map the human genome. On the other, we are the first generation seriously to lay waste to the environment. Human activity is draining resources and destroying natural habitats. We are changing our surroundings to such an extent that people think of our time as an entirely new geological era.

Climate change and sustainable living

Jostein Gaarder

Huge volumes of carbon are contained in plants, animals, the sea, oil, coal and gas. The carbon is just itching to be oxidized and released into the air. The atmosphere on dead planets such as Venus and Mars is mostly CO2, and that would also be the case here if the Earth’s processes didn’t hold the carbon at bay. But from the end of the 18th century, fossil fuels have tempted us like the genie in Aladdin’s lamp. “Release us,” they whispered. And we gave into that temptation. Now we are trying to force the genie back inside the lamp.

If all the remaining oil, coal and gas on this planet is extracted and burnt, our civilization will not survive. But many people and many countries see this as their divine right. Why shouldn’t they use the fossil fuels on their land? Why shouldn’t countries with rainforests chop them down? What’s the difference? What difference will it make to CO2 levels or to biodiversity if one country stops while the rest carry on?

Over the past few centuries, most people here in Norway have been lifted out of poverty. The same is true in many regions of the world. We should not forget that. But this prosperity has come at a high price, a debt we are only now beginning to pay off. Before the Industrial Revolution, the atmosphere contained 275 CO2 parts per million. At the moment of writing, that figure is 400 ppm and it is still rising. Devastating climate change is unavoidable at this rate. Sooner or later we must attempt to return to pre-industrial CO2 levels. 

According to Dr James Hansen, considered by many to be one of the world’s leading climate researchers, we must – initially at least – get this level down to 350 ppm. Only then can we feel reasonably secure that we will escape the worst catastrophes for this planet and for our civilization. But the figure is not going down. It is going up.

If we are to save biodiversity, we need to revolutionize our thinking. Living as though everything centers on our time is just as naive as thinking the Earth is flat. Our time is no more significant than future times. It is only natural that our time is the most significant to us. But we cannot live as though our time is also the most important one for those who come after us. We must respect future times as we respect our own time.
In relationships between individuals and between nations, we have emerged from our “natural state”, characterized by the survival of the fittest. But when it comes to the relationship between generations, unbridled lawlessness still reigns.

Everyone has the right to practice their beliefs, and everyone has the right to hope that our planet can be saved. But that does not guarantee that there will be a new heaven and a new earth awaiting us. It is unlikely that supernatural forces will bring about a Judgement Day. But it is inevitable that we will be judged by our descendants.

Climate change comes down to greed. The destruction of biodiversity comes down to greed. But greed does not trouble the greedy. History is our witness. 

The ethical question is not difficult to answer – what is difficult is living by the answer. But if we forget our descendants, they will never be able to forget us. The question of how widely we should apply the reciprocity principle comes down to identity. What is a human being? Who am I? If I were merely myself – that is, the body sitting here writing – I would be a creature without hope. But my identity goes deeper than my own body and my own short time on Earth. I am a part of – and I take part in – something which is bigger and greater than myself. Humans tend to have a local and short-term sense of who they are. We used to have to scan our surroundings, wary of dangers and prey. That gives us a natural tendency to defend ourselves and protect our own. But we do not have the same natural tendency to protect our descendants, not to mention species other than our own.

Favoring our own genes lies deep within our nature. But we don’t have the same instinct to protect our genes four or eight generations down the line. That is something we must learn – just as we had to learn to respect human rights. Ever since our species emerged in Africa, we have fought a determined battle to prevent our branch of the evolutionary tree from being cut off. That battle has been successful, for we are still here. But we have become so prosperous that we are threatening the basis of our own survival. We have become so prosperous that we are threatening the basis of every species’ survival.
As clever, vain and inventive as we are, it is easy to forget that we are simply primates. But are we really so clever if we put our cleverness and inventiveness ahead of our responsibility for the future of the planet?

No longer can we think only about one another. The planet we live on is an essential part of our identity. Even if our species is destined to die out, we still carry an important responsibility for this unique planet and for the nature we leave behind. Modern humans think we are almost entirely shaped by our cultural and social history, by the civilization which produced us. But we are also shaped by our planet’s biological history. There is a genetic heritage as well as a cultural one. We are primates. We are vertebrates.

It took billions of years to create us. Billions of years to create a human being! But are we going to survive the next millennium?

What is time? First we have the horizon of the individual, then of the family, of culture and of literary culture, but there is also geological time – we come from tetrapods that crawled out of the sea 350 million years ago – and finally, there is cosmic time. Our universe is almost 13.7 billion years old.

But in reality, these periods of time are not as distant from one another as they may seem. We have reason to feel at home in the universe. The planet we live on is precisely one third of the age of the universe, and the class of animals to which we belong, the vertebrates, has existed for a mere 10 per cent of the time our solar system and life on Earth have existed. The universe is no more infinite than that. Or conversely: our roots and our kinship are intricately and deeply woven into the universal soil.

Human beings may be the only living creatures in the entire universe who have a universal consciousness. We have a staggering sense of the immense and mysterious cosmos we are part of. Therefore, not only do we have a global responsibility to save our planet. We have a cosmic responsibility.”

 Agrivoltaics: Growing Food for the Future


Agrivoltaics: Food and Solar

“Agrivoltaics combines agriculture with energy efficiency while growing plants beneath solar panels.”

By Linn Smith

January 28, 2018—- Co-location means two or more groups, sharing the same place. Agrivoltaics, also known as Agrophotovoltaics, means using the same piece of land for solar power plus agriculture. Agrivoltaics, or solar farming, is a new way of growing plants, combining agriculture with energy efficiency while growing plants beneath solar panels.

Agrivoltaics: Dual Use of Land

In 1981, Adolf Goetzberger and Armin Zastrow developed the idea to improve overall production of crops. Dr. Goetzberger founded the Fraunhofer Institute for Solar Energy Systems in Germany. His work involved making solar an alternative to fossil fuels. In 1981, he published a paper titled, “Potatoes under the Collector,” which proposed a setup for solar energy systems in combination with agricultural land use.


Growing food with solar

Dr. Eicke Weber, Director of the Fraunhofer Institute stated, “In view of the dynamic worldwide growth of solar installations of the last decade and the increase in land usage resulting from solar installation systems, innovative concepts, like agrophotovoltaics (agrivoltaics) which facilitates the dual usage of agricultural land, help to further and accelerate the transformation of the global energy system.”

Dr. Goetzberger used the term Agrophotovoltaics or APV, as a method of harvesting the sun for both power and production of crops. APV is currently an ongoing project in Germany which demonstrates that land for both growing crops and solar electricity are compatible. Dual use of the land is resource efficient, reduces competition for land and opens up a new source of income for farmers.

The APV System

The APV system was installed on organic farmland in Germany in 2015. Approximately seven acres were used to produce crops under the ground-mounted solar panels, which were built about 5 yards off the ground. Four different crops were planted. The land in use not only generates electricity from the solar panels but is also growing food. The solar panels provide a uniform light distribution on the crops using reflection. To prove their theory, they also planted a control plot nearby using the same 4 crops, excluding the solar panels. The scientists wanted to determine which crops would grow best. Result: The crops under the APV system produced about 80% of that of the control crop. This experiment is ongoing and data will be analyzed in 2018.


Agrivoltaics: Growing food to feed the planet.

Agrivoltaics and Biosphere2

A similar experiment was being conducted at Biosphere2 when I visited several weeks ago. This research, headed by Barron-Gafford, Assistant Professor, revealed that the solar system above the crops created a warmer environment than normal when no plants were beneath , similar to the heat-island effect that happens in cities surrounded by cement and asphalt. He stated, “So think about it, if you get rid of all the plants when you put in renewables energy, you’ve gotten rid of that cooling potential… plants under the panels would allow the air to circulate and would take up carbon for photosynthesis by opening up their pores, or stomata, while letting water escape from their leaves and you get a warmer environment. We wanted to see if you put the cooling effect back into the system by growing plants beneath the solar panels, you can actually cool those panels back down and mitigate that heat island effect.”

When solar panels get too warm they start to lose their efficiency. By growing plants beneath the panels they can cool down and retain that efficiency, which makes for more renewable energy per parcel of land. The panels also shade the plants, reduce evaporation and the crops require less water to grow underneath.



In the future, as world population grows, solar and land for food must not be in competition. The world population today is approximately 7.6 billion. Two hundred years ago it was 1 billion. At the close of the 21st century the population will be more than 11 billion. The question remains…will we be able to feed our planet’s population and meet the demand for clean energy?

Tesla: What’s New?

Model Y Tesla

Model Y, Tesla’s car of the future.

“Elon Musk is still at the forefront as a founding father of the rapidly changing electric car industry.”

By Linn Smith
November 26, 2017—-When I happen upon a Tesla owner charging their car at a charging station, as I did recently in Trinidad, Colorado, I usually linger long enough to ask the owner his opinion of the Tesla. The responses are always similar, “Best car I ever owned,” or “Most fun car I ever had.” The people who own the Teslas are the best advertisement for these all electric vehicles. Some of the reviews I have read on line are mixed, but testaments “straight from the owner’s mouth,” have been strongly positive!

Tesla: A Review

The Tesla Model S was introduced in 2012. Several revisions in 2017 have improved the driving range per charge to between 270-335 miles. The 40-amp charger of earlier models was replaced in 2017 with a 48-amp charger, which enables a quicker charge and about 30 miles drivable time per hour of charge.

Tesla electric cars

Charging up at a station

What’s New for Tesla in 2018?

*The Model S 100D has a range of 335 miles with the ability to hit 60mph in 2.5 seconds (if you’re into speed).

The Model 3, with a base price of about $35,000, reportedly is, “Adopting a controversial plan to forgo prototype tooling (a test model design) in an effort to accelerate the launch of the Model 3.” Test drivers, journalists and financial analysts were given hands on demonstrations of the car and loved it! 

AllianceBernstein says, “We found the Model 3 to be a compelling offering, and believe it is likely to further galvanize the overall Electric Vehicle category.”

Though Tesla has struggled getting the Model 3 available to the public, it promises to be available soon. Tesla’s target of producing 5,000 Model S’s by the end of December has been pushed to March of 2018.


All electric semi will change the way cargo is hauled across country.

The Tesla Semi

In the meantime, Musk has unveiled his electric semi-truck and Roadster sports car this week, and may unveil an SUV, Model Y soon.

Tesla will be the first user of their semi-trucks, hauling cargo between its California factory to one in Nevada. “Tesla will be the first customer for the semi. We will use our own truck to carry cargo in the U.S. between our different facilities. We have an assembly facility in California, the Gigafactory in Nevada, so we will use our trucks to carry things in-between.” This electric semi has a range of 500 miles on one charge, which is approximately the round-trip mileage of 80% of the trucking market. The price of the electric semi would compete with the sale of regular gas semis.

The Model Y (Unofficial name) will be a small SUV, which was going to be built on the Model 3 platform but is now back to the original plan in building it separate in order to bring it to market sooner. It will be a more automated production line, bringing it to market faster, as SUV’s are one of the fastest growing vehicles.

So, Elon Musk is still at the forefront as a founding father of the rapidly changing electric auto industry, with the other car manufacturers scurrying to keep pace with his Tesla company! Tesla has confronted many obstacles, but still moves ahead to combat our warming climate.

Climate Change Over Geological Time

Glacial Ages and Climate

Climate Change Over Time

“Climate change at the present is of great consequence to most species including humans.

By Dr. John J. Hidore

November 15, 2017—-Planet Earth was formed about 4.5 billion years ago. Geologists have divided this long history of the planet into several pieces called eras. They are the Precambrian, Paleozoic, Mesozoic, and Cenozoic.

The Precambrian is the longest and each of the other three are shorter than the previous one. When considering climate change through geologic time, two aspects stand out. The first is that for most of geologic time Earth has been warmer than it is at present. How much warmer varied through time. The second feature that stands out is the intermittent ice ages when large portions of the earth were covered with ice.

Major Ice Ages

Relatively little is known about the long period of Precambrian time. Basically it was the period during which the earth cooled from its initial very hot state. The Paleozoic, Mesozoic, and Cenozoic eras encompass the rest of geologic time, about 570 million years. More evidence, and a greater variety of
evidence, is available about the environment during these eras. The climate of Earth varied widely during this time. However, it has been established that there were three known periods of glaciation in Precambrian time. They were:

Archeozoic 2250 million years ago (mya)
Early Precambrian: 950 million years ago
Late Precambrian: 750 million years ago

There were four major glaciations following that of the Precambrian era. They were:

Early Cambrian: 650 mya
Ordovician: 450 mya
Permo-Carboniferous: 350-250 mya
Pleistocene: 1.8 mya until recent time

Following the ice age at the end of the Precambrian, the earth rapidly warmed. For the remainder of the history of the earth, temperatures have averaged 5 degrees C (9°F) higher than at the present. These warmer conditions existed probably 90 percent of the time over the past 570 million years.

The Permo-carboniferous Ice Age

An ice age, called the Permo-carboniferous, began at the end of the Paleozoic Era. It began about 325 million years ago and lasted until about 250 million years ago. The South Pole was in the midst of the large land mass called Gondwanaland. Ice sheets moved over about half of this large land mass. What is now Antarctica and parts of Australia, India, Africa, and South America were covered with ice. The glaciation of each of these areas did not take place at precisely the same time, but they were all affected by the same climatic cooling. The Southern Hemisphere suffered widespread glaciation, but the Northern Hemisphere remained warm. The most appealing explanation for this situation is a different relative location of the land masses. The northern continents were nearer the equator and the southern land masses nearer the poles.

Climate Change

Climate Change over time.

The Warming of the Earth

After the glaciation in the Permo-Carboniferous ice age, the earth again entered a long period of warm conditions. The period of warmth continued through most of the Mesozoic Era and the earth was free of glaciation. Temperatures were warm and rainfall was abundant on the land masses. Even the polar regions experienced mild weather. Initially, the warmer conditions resulted from the slow migrations of the large southern hemisphere land mass to the north. This carried areas that had been glaciated into warmer climates.

The Pleistocene Ice Age

The most important single environmental event since the human species has been on earth has been the oscillation between glaciation and interglacials during the Pleistocene Epoch. The epoch represents a large change from much of the last 570 million years. This ice age is the most recent of the major cold periods to occur over the history of the planet. During the time when the ice was most extensive over Earth, temperatures averaged about 4°C (7°F ) lower than those of the present. In the northern hemisphere it was perhaps 8 to 12 °C ( 14 to 22°F) lower than current temperatures. 

There is no question but what the climate of planet earth has changed frequently, and sometimes drastically, over geologic time.

Climate Change Today

Climate change at the present is of great consequence to most species including humans. There is really no way of knowing how much change will take place in the foreseeable future nor how much is due to the activity of our species. What is known is the earth is warming rapidly at this time and that all evidence points to human activity as bearing the responsibility.

Now is the time to take international action and not only support the Paris Agreement, but take even more drastic measures to curtain the warming!

Puerto Rico: Rebuilding Sustainably

Renewable Resources


“Building sustainably in Puerto Rico can take many different forms.” 

By Linn Smith

October 19, 2017—Even though Puerto Rico is going through a devastating time after the hurricane, it is essential that we not only meet the current needs of the people, but also think about its future….rebuilding sustainably. Areas devastated by wind and flooding must not only think about immediate needs, but consider the future way climate change may threaten vulnerable coastal areas. 

There is an agreement among scientists that our warming climate is producing larger, more aggressive hurricanes, and rising oceans are leading to stronger storm surges, destroying and flooding inland areas.

Puerto Rico: Sources of Energy

According to the U.S. Energy Information Administration, Puerto Rico has some renewable solar, wind, hydropower and biomass resources, but relies primarily on imported fossil fuels to meet its energy needs, importing mostly from the U.S.

In 2016, Puerto Ricans paid more for their power than people in any other state except Hawaii, with 47% of electricity coming from petroleum, 34% from natural gas, 17% from coal and only 2% from renewable energy.

The Future of Energy in Puerto Rico

Now is the time to make decisions about Puerto Rico’s future energy needs. How will Puerto Rico get its power in the future? PREPA, the Puerto Rico Electric and Power Company, Puerto Rico’s only utility company, is mismanaged and highly in need of upgrading according to some sources. According to, it would be a waste to pour more money into this system. Instead, we need to invest funds into local renewables and energy efficient transportation, such as streetcars and light rail trains. 

Richard Heinberg in the article “Disaster in Puerto Rico” stated, “This is a chance to build back sustainably. People tend to maintain their status quo as long as it’s viable, but when in dire straits, they’re more likely to listen and when denial is no longer possible, people are more likely to face reality.”

Eigg renewables

Eigg uses 99% Renewable Energy

Eigg, Scottland: 99% Renewable

According to an article by David Nield, March 2017,, researchers from around our planet are visiting the tiny, Scottish island of Eigg, which is using wind, solar and hydo to obtain the island’s power. This system, owned and operated by the island’s residents, has been using sustainable energy since 2009. Eigg Electric uses a combination of sustainable resources to ensure there is always energy. When back-up energy is needed, it’s supplied by several diesel generators with cables linking all the sources of energy together. Renewable energy is used 95% of the time and excess energy is stored in a bank of 100 batteries. When these batteries are full, electric heaters automatically switch on in the church and community hall so nothing is wasted. Eigg’s population has doubled since this system has been in place, but the system is still meeting the needs of the residents. The drawback is that citizens are limited to the amount of power they can use daily from the public utilities
Ta’u, a small island in Samoa, is also changing from diesel to renewables. Today it’s powered by 5,000 Solar City solar panels and 60 Tesla Powerpack battery storage units. The Powerpack is a massive battery, 16 Powerwall battery pods encased in a weatherproof box, that can store electricity during the day when supply is abundant and discharge it when demand goes up after the sun goes down. This system provides the island with about 99% of its needs.

Tesla solar project in Hawaii.

Tesla and the Powerpack Battery

Tesla has also built a huge solar energy plant on the island of Kauai, one of Hawaii’s main islands. This project will reduce fossil fuel by 1.6 million gallons per year. The island signed a 20 year contract with Tesla to buy solar generated electricity from solar panels installed on the island for 13.9 cents per kilowatt hour. The average price of electricity in Hawaii is 37.34 cents per kwh, the highest rate in the nation. Kauai is the first major solar/storage project for Tesla. Tesla states, “We will work with energy providers around the world seeking to overcome barriers in the way of building a sustainable, renewable energy grid of their own.”

Tesla is also in the process of shipping battery packs to Puerto Rico, but details of the project have not yet been made available. Building sustainably in Puerto Rico can take many different forms and accepting help from Tesla could be a starter.

Living Green: Using Our Resources 

building green

Cities, states and individuals must do their part in preventing climate change.

Remember: Recycle, Reduce, Reuse!

By Linn Smith

October 12, 2017—-People in developed countries are losing the ability to be resourceful! We “run to the store” impulsively on a daily basis. How did folks survive without today’s conveniences? Today nearby stores provide us with our every need, and we too often toss excess and unused products in the garbage, leaving our landfills and oceans overloaded with toxic materials that may never decompose!

Growing up on a farm, we grew most of our own food. Our basement was lined with many shelves containing hundreds of jars filled with colorful, canned foods from our garden. Cows, pigs and chickens provided us with fresh meat, and our dairy cows provided the milk we drank, and it wasn’t pasteurized! My mother strained the milk through a cheesecloth to get the big chunks (of whatever) out…..and my brothers, sisters and I all grew up healthy! Farm life was what we call green living today….but back then it was just life!

Families use to be resourceful. To obtain something they needed, they reused, fixed, mended or created something new from what they already had.  My grandmother created children’s mittens from old sweaters, it saved money and no new items were purchased.

Earth Day today and every day!

Eco-friendly Steps to Going Green

What are some eco-friendly steps we can take to conserve today? Here are just a few:

1. Turn some of your yard (or all of it) into a garden and can or freeze the vegetables. Yards were originally for very wealthy families in England, who used sheep to keep the grass trimmed. Lawns weren’t meant to look like  golf courses. They had dandelions and clover. Today our lawns are toxic with chemicals and leave  huge carbon footprints!

2. Buy unpackaged products from local farmers at farmer’s markets.

3. Cook from scratch instead of buying processed food. It tastes better!

4. Make restaurants an occasional option, not a daily trip. (This includes Starbucks!).

5. Buy second-hand from used stores, garage sales, or auctions. Fix, mend or make-do.

6. Don’t buy more than you need. Several years ago we stored most of what we thought was our valuable “stuff” and went RVing. It cost well over $1000 to store. When we returned and assessed our “stuff,” we realized we could live without most of it. We had a garage sale, making several hundred dollars from the sale of our valuables that had cost over a $1000 to store!

7. Recycle and compost.

Clean Energy: Make It a Priority!

Why Not Go Green?

Here are some excuses people make to avoid helping our planet:

1. It’s too expensive…BUT, if you shop around most things are comparable.

2. One person can’t make a difference….YES, you can! Good thing everybody doesn’t feel this way!

3. No one else around me is living eco-friendly…..WELL, THEN….how ’bout you be the first!

4. It’s too late. The planet is already doomed….OK, pull your head out of the sand and look around at what positive people are doing!

5. Global warming is a myth. NO IT’S NOT! (But I won’t waste my time arguing with you on this point!)

6. It takes too much time and effort. It’s like anything else, it becomes routine when done on a regular basis.

Before you buy something, ask yourself if you really need it, or is there something you already have that could be used…or ask, Can I make do with less?

The Carbon Footprint of Air Conditioners

“The world’s supply of A/C units could increase from about 900 million in 2015 to roughly 1.6 billion by 2030.”

By Linn Smith

August 20, 2017—-If solar airplanes can fly, then maybe it’s time we look at solar for our air conditioning. According to a 2016 study at Berkeley National Laboratory, nations with emerging economies and spiking populations, including heavily populated India, are seeing air conditioner sales grow 10 to 15 percent a year.

What does the increase in air conditioning mean for our warming planet? The world’s supply of A/C units could increase from about 900 million in 2015 to roughly 1.6 billion by 2030. The Berkeley study says new technologies must take the place of hydroflourocarbons, (HFCs), found in most air conditioners. HFCs are growing rapidly in our atmosphere with a potential to increase the greenhouse effect faster than carbon dioxide, because they trap heat in our atmosphere at levels 1000 times greater than CO2.

In 2016, 200 nations gathered for the United Nations summit meeting on climate change. Negotiators created a deal to ban the use of HFCs in air conditioners and refrigerators, with finalization at the Kigali, Rwanda climate conference a few months later. 170 countries successfully negotiated an amendment to the Montreal protocol treaty to get rid of 90% of the HFCs. Developed counties will begin phasing out HFCs in 2019, China in 2024, and India and other counties in 2028.

Nearly all HFCs are made by a few giant western chemical companies, including Flame Guard USA in Illinois, GMC Aircon in South Africa, and OB-1 Air Analyses, Inc. in California.

Cities, states and individuals must do their part in preventing climate change.

Reducing HFCs

The search is on for clean technologies to take the place of HFCs. In Australia, the Solar Hybrid Air Conditioner is offered by the company, EcoWorld. EcoWorld claims you can stay cool without the huge energy bill. This unit costs about $2700AU or $2000 U.S. dollars. You can see it at

They state:

1. Hands down this is the cheapest-to-run 3.5kW Split System Air Conditioner you can buy.
2. Stay Cool or Warm without the huge energy bills. Use it more often without regrets.
3. Pays for itself, in energy savings alone, within 7 months of running time.
4. Runs automatically between both Solar DC Power and 240V AC Mains.
5. 12000 BTU Performance without costing the earth.
6. As the sun goes down it transitions over to the mains power supply.
7. Comes with a 6 Year Australian Warranty when installed by a certified air conditioner installer.
8. Rated to cool or heat around 30-40 square meters.
9. Filters pollen particles from the air and can also dehumidify your space.
10. Helps to reduce Greenhouse Gas Emissions back at the power station.
11. Highly efficient and feature packed 3.5kW split system inverter air conditioner.
12. Uses 1kW of solar panels (typically 4 x 250W panels in series).
13. When running together with the solar panels it uses as little as 30W of 240V AC mains power which is virtually nothing compared to standard air conditioners.

Can we wait until 2019, 2024 or 2028 to cut HFCs? Will it be too late? Now is the time to take a step towards saving our planet! New technologies must replace fossil fuels and chemicals, such as HFCs, that contaminate our atmosphere!

The Galapagos UNESCO Heritage Site in Danger

Galapagos islands at risk from climate change

Home to many rare species of plants and animals

“In 2007 UNESCO listed the Galapagos as threatened, as a number of the most unusual creatures found on the islands were in decline.”

By Dr. John J. Hidore

August 11, 2017—-The Galapagos Islands are located about 600 miles west of the coast of Ecuador. There are 13 major islands in the group, in addition to dozens of smaller rock outcrops. They were discovered in 1535 by sailors engaged in exploration. These islands are a unique treasure on our Planet.

The Galapagos Islands have been designated a UNESCO Heritage Site. When explorers first described the islands to people on returning to their home ports, most people did not believe the stories that were told.

The Galapagos Islands are significant for a variety of reasons. First, there is no other island ecosystem like it. They are home to many species of plants and animals not found anyplace else on the planet. The animals include blue footed boobies and marine iguanas. Second, it is the setting for the work of Charles Darwin in formulating the theory of evolution that was published as The Origin of Species. Charles Darwin visited the islands in the year 1835. At the time, the islands were known as Las Encantatas or the enchanted ones.

Galapagos Islands and climate change

Galapagos animals and plants are at risk due to global warming.

Climate Change is Altering Life on the Islands

Global warming has already raised the temperatures over the islands. The islands generally receive little rainfall. Parts of the islands depend on cool season fog to provide condensation for plants. Additional warming may eliminate this weather pattern which is the only source of moisture for vegetation is some areas. Increased rainfall that may come with a changing climate may also lead to the decline in many species of plants.

The warmer conditions are causing vegetation zones to move to higher elevations. The rising temperature is also affecting the ratio of males to females in some turtles. Warmer temperatures tend to produce more female offspring, a phenomenon that has been observed at different locations around the world.

The mean temperature of the surrounding ocean of the islands is rising. Like other regions that lie astride the equator, coral bleaching has now been observed to occur in the reefs around the islands. The bleaching is an indication of not only global warming of the atmosphere, but of the warming of the tropical oceans. While corals live in warm water they will not live in water that is even a few degrees above their optimum temperature range. As the ocean warms they are also expected to become more acidic. This will increase the rate at which minerals are dissolved from the reefs.

Sea level has been rising and is expected to rise even more. The only question is how much more it will rise. Estimates of sea level rise by 2100 vary  with the highest estimates rising 30 inches. Rising sea level may destroy many of the mangrove forests which are home to some unique species of birds including some species of finch.

Invasive Species

There is a second problem which may be a greater threat than climate change to the uniqueness of the islands. This is the introduction of plants and animals not native to the islands. It is believed there are now more than 1400 introduced species on the islands of which more than half are plants.

Many of the introduce species have been accidentally introduced. Probably among the first were rats, which jumped ship over the years. The rats thrived and the population grew rapidly. Many other species of insects and plants were probably introduced at the same time. The accidental introduction continues as other species of plants and animals come to the islands along with the importing of merchandise.

Other species of plants and animals have been deliberately introduced. Among the first were domestic goats. They were often kept aboard ship for the purpose of supplying meat and milk for a ship’s crew. On the Galapagos some of the goats escaped to become wild. Their numbers increased and they began devastating the natural vegetation. In recent years major programs to eliminate the goats have been initiated, especially on the smaller islands. In 2006, for example, a massive effort was mounted to eliminate some introduced species from several islands.

Largely due to problems related to the invasion of species, in 2007 UNESCO listed the Galapagos as threatened, as a number of the most unusual creatures found on the islands were in decline. This includes sea lions which depend on a declining food supply off shore. The changing of the plant communities is a threat to many native birds. Some of the very species of finches which were the foundation of Darwin’s theory of evolution are in danger of becoming extinct.

On the plus side, most native species are expected to survive if invasive species can be controlled. But again, additional climate warming may eliminate the weather pattern necessary for plant and animal survival!
