Removing Carbon Dioxide from our Atmosphere

Carbon Engineering

Cleaning CO2 from our atmosphere.

“CarbonEngineering:“Commercialization of Direct Air Capture (DAC) technology that captures CO2 directly from the atmosphere at an affordable price.”

By Linn Smith

According to NASA, in a report from June 2019, CO2 in our atmosphere reached 412ppm (parts per million) which hasn’t been seen in human history. CO2 is the gas that we humans are rapidly releasing into our atmosphere, trapping heat similar to a greenhouse. It is a result of burning fossil fuels such as coal.

The Rise in Earth’s Temperature

Earth’s average temperature has risen 1.62 degrees F since late 1800’s, with most of the rise in temperature occurring in the past 35 years. The 5 warmest years have occurred since 2010! At this point in history the answer to survival of life on our planet is multifaceted. We must work to not only offset our personal CO2 emissions, but also seek ways of CO2 removal from our atmosphere before it’s too late
.

Carbon Offsets

A carbon offset is an action everyone can take. It means compensating for your emissions in one part of your life by working to cut CO2 emissions somewhere else or contributing to programs that are working to combat global warming.

Unless you’re driving an electric or hybrid, an average car can emit about 5 tons of carbon dioxide into the atmosphere each year. Can you plant enough trees in your yard to offset your car pollution? Probably not.

There are many online sites that will calculate your CO2 footprint with recommendations to offset emissions, such as planting trees, or you can go to the EPA website and use their carbon footprint caluculator to calculate the carbon footprint of you and your family.

Clean Energy: Make It a Priority!

Planting Trees to Offset Your Carbon Footprint

According to http://www.urbanforestrynetwork.org, “On average, one acre of new forest can sequester about 2.5 tons of CO2 a year. Young trees absorb about 13 pounds per tree each year. Trees reach their most productive stage of carbon storage at about 10 years, at which point they are estimated to absorb 48 pounds of CO2 per year.”

An MIT study states that the average CO2 emissions emitted per person per year in the U.S.. is 20 metric tons, compared to the world average of 4 tons.

Carbon Engineering

CO2 is turned into clean fuel.

Carbon Engineering

Jennifer Wilcox states in her TedTalk that we have the technology to clean up the atmosphere, but it has been too expensive until now. Companies are currently working to bring down this cost. One company, Carbon Engineering, www. carbonengineering.com, is focusing on “commercialization of Direct Air Capture (DAC) technology that captures CO2 directly from the atmosphere at an affordable price.” They do this in a “closed loop where the only major inputs are water and energy and the output is a stream of pure, compressed CO2 that can be stored underground or converted into fuels using AIR To FUEL technology.”

“AIR to FUEL uses CO2 captured from the atmosphere to synthesize clean transportation fuels. It uses renewable electricity to generate hydrogen from water, and then combines it with CO2 captured from atmosphere to produce hydrocarbon fuels such as diesel, gasoline and Jet-A, all with little or no fossil carbon emissions to the atmosphere. Individual facilities can be built to capture one million tons of CO2 per year which is equivalent to 250,000 average cars per year.”

Combating global warming

We all have a responsibility to do our part with no more excuses! We can’t wait for someone else to do it. For survival on earth, we need to stabilize the ppm (parts per million) of greenhouse gases in our atmosphere. The outcome of doing nothing about our changing climate is mass extinction of species, including our own, caused by extreme weather and our changing climate.

The Island of Greenland Responds to Climate Change

Climate change

The rapidly melting artic

“The melting of the ice on Greenland is significant!”

By Dr. John J. Hidore

There is no doubt that Planet Earth is warming relatively fast. Data of all kinds supports this allegation. The data include biological, geological, hydrological and climatological. The year 1880 has been established as the beginning of a period of accelerated warming due to the increased use of fossil fuels and a growing population. From 1880 to 1979, the global temperature increased 0.1°F (0.05ºC) above the pre-industrial average. By 2016, the global temperature had climbed 1.4°F(0.6ºC).

Arctic Ocean

Melting of the Arctic Sea Ice

Northern Hemisphere is Warming Faster than the Southern

Climate normals are periods of 30 years that move forward every 10 years. The current normal being used is that of the period 1980-2010. When compared to the 30 year global average for the period 1980-2010, the northern hemisphere is warming faster than the average for the earth as a whole. It is also warming faster than the southern hemisphere. The reason the Northern Hemisphere is warming faster than the southern Hemisphere is due to the fact that most of the earth’s land mass is in the Northern Hemisphere.

climate change

The exchange of energy is causing rapid arctic melting.

The Arctic Region is the Most Rapidly Warming Region in the Northern Hemisphere

The Arctic is the coldest region in the Northern Hemisphere. The region consists of the sea surrounding the North Pole and land that rings the sea. The arctic is warming faster than mid-latitude or tropical regions. It is warming more than twice as fast as the average for the earth. The reason for this is, as ice and snow melt on the fringes of the arctic, the ratio between reflection and absorption of solar energy changes drastically. In the winter the sea is covered by a veneer of ice and the surrounding land is generally covered by snow. With the onset of summer the increased solar radiation results in the melting of the ice and the snow melting off the land. The more snow and ice that melts, the faster the arctic warms. This change results in what is known as a positive feedback mechanism. More and more energy is absorbed rather than reflected or used to melt the ice. As the melting season lengthens the land and atmosphere above it warm faster than areas further south. While the Arctic is still the coldest region in the Northern Hemisphere, it is warming more rapidly than other areas.

Climate Change is altering the World’s largest Island

Greenland has the most extensive ice cover of any island on the planet. In much of the region the ice is more than a mile ( O.6 km) thick. The melting of the ice sheet has been monitored by satellite since 1979. The ice sheet normally starts to melt at the end of May. In 2016 the ice began to melt in mid-April. The higher temperatures resulted in early melting of the ice sheet. In the second week of June there was melting over nearly half of the ice surface. This was a record area of melting for this date. Part of the reason for the extensive melting this year was the light snow cover during the past winter. It melted fairly quickly allowing the sunshine and warmer air to increase melting in the older snow and ice beneath. How much melting occurs on any given day depends on wind direction and cloud cover.

The year of 2012 was the record year for total melting of the ice sheet. The town of Narsarsuaq recorded a temperature of 76.6°F. In that year there was a net loss of some 200 billion tons of ice.

Climate Change, Global Warming

Climate Change Affects Everyone!

Selected High Temperatures

2012 Marsarsuaq May 76.6 °F
2013 Manitsoq July 78.6 °F
2014 Kangerlussuaq Jan 73.8°F
2016 Nuwk June 75 °F

Spring temperatures came early to the Arctic this year. The island of Greenland experienced these early warm temperatures. Average temperatures exceeded normal by several weeks. In some areas the temperatures were as much as 40° F (22°C) above normal. The early warm temperatures have resulted in early and extensive melting of the ice sheet.

The melting of the ice on Greenland is significant because it is the major source of water for the current rise in sea level. If all the ice melted it is estimated that it would raise sea level approximately 24 feet (7.3 meters). Since data has been collected, in the early 1970’s, sea level has risen about ½ inch (1 ¼ centimeters).

Coal: Still Visible but on the Decline!

Coal Plant

Coal waiting to be burned at the local utilities plant.

“Our time is up! We no longer have time to sit back and say it’s someone else’s concern!”

By Linn Smith

During my annual trek back to the Midwest where I call home, I had plenty of chances to observe that coal is still alive and well, although in my home state, wind turbines are popping up by the hundreds.

Coal sits at the local utilities plant in my hometown.

Yes, piles of coal are still scattered throughout the region and being hauled on trains, but the overall growth rate of coal use has diminished. According to the Institute for Energy Economics and Financial Analysis, the use of coal in the energy sector of the U.S. is declining.

coal train

A frequently seen site along the tracks in the midwest.

Coal is on the Decline

The reason for coal’s decline is mostly economical. Here are several reasons for the decline:

1. Good or bad, the nation has turned towards greater use of natural gas. Even though fracking is the method of extracting natural gas, it burns cleaner than coal. Hopefully it’s just the middleman as we move towards clean energy!

2. Declining costs of renewables.

3. Aging of our coal plants which are leading to greater cost to the consumer.

4. Climate change and extreme weather have caused greater concern in public opinion, leading to a willingness to move toward renewables.

5. Corporations and oil companies have adjusted their economies towards public concern. They may still lack the concern for our planet…but money speaks, and if public opinion and price of renewables are telling them to move away from fossil fuels, then they are forced to listen!

Coal Consumption

Coal is on the decline, but is it fast enough?

Someone once said that people wouldn’t listen to the concern about climate change until it was in their own backyard and that seems to be what has happened! Extreme weather, a predicted effect of climate change, is happening around the world in the form of floods, water shortages, depletion of rivers, storms, heat and extreme cold. Our time is up! We no longer have time to sit back and say it’s someone else’s concern!

Building Sustainable Cities

“Sustainable planning must come before greed!”

By Linn Smith

I live part of the year in a rapidly growing city. I have lived in this city for 20 years, 15 years full time. In the past 5 years there has been a mass migration to this city. Traffic has come to a halt at rush hour, which now starts as early as 2:30pm and extends until early evening, accidents can hold up traffic for hours and parking spaces…forget about it! Developers of the city transit system have been involved in lawsuits with city transit, halting development in some areas for years, costing the city millions of dollars.

The High Price of No Sustainable Plan

Housing prices have tripled…. $500,000 being the price of the average home. We are diminishing the habitat of wildlife in a former mecca for bears, wildcats, moose and elk. The plan for their intrusion on us is 3 strikes you’re out. If a bear is found in a populated area 3 times it is euthanized and this is happening more and more with city sprawl….we have intruded on their space and there are severe consequences to them….for intruding in “our” space!

Pollution and air quality are rapidly declining. We are now the 12th most polluted city in our country.

Profit Before Sustainability

Well thought out planning? Jobs, yes, sustainable planning, no! Money has spoken clearly, developers and contractors have become rich. The city’s motto seems to be, “Build for those who come at any cost to the environment.” I am both amazed and disgusted to see the growth without planning. Why do I live here? I migrated here from the agricultural areas of the U.S. for a teaching job, and now my family is here.

It may be too late for this city, but my hope is that other cities will plan before sprawling unconsciously, building on every green patch of grass available without thought of the cost to our planet and the future of our survival!

building sustainably

Building sustainable cities

According to data provided by the United Nations, 68% of the world population will live in urban areas by 2050….that is approximately 2.5 billion people migrating from rural to urban areas! (This also includes projected overall growth in human population). North America currently has 82% of the population living in urban areas. Understanding these numbers is going to be critical for planning sustainable cities. Sustainable planning must come before the dollar signs shining in the eyes of contractors and developers!

What is a sustainable community?

Green, sustainable communities implement multifaceted methods of environmentally sustainable practices, changing city government to support these practices so that present and future generations can have clean, healthy environments and a planet that will continue to support humans and flora and fauna. Steps towards a green community should be outlined with measurable goals to see the growth on a continuum of ongoing sustainable practices….i.e. conditions that will not harm the environment.

Sustainable cities

Campbell’s Triangle plan

Building Green Ideas

1. Parks and Green spaces are meant to be part of a city’s health for residents, not future places for buildings to be developed.
2. Bike lanes and bridges should be separate from streets and highways.
3. Build or refurbish all government buildings to reflect the sustainable city vision.
4. Buildings will be renovated instead of torn down.
5. Comprehensive recycling and composting programs.
6. Green leadership with leaders who already live sustainably.
7. Smart energy policies.
8. Efficient public transportation.

Again, sustainable development must come before of greed!

Extreme Storms: The recent bomb cyclone in the United States and tropical cyclones in southeast Africa

Climate change causes severe weather.

“In all probability it is a result of climate change and indicative of things to come.”

By Dr. John J. Hidore

A Bomb Cyclone Forms in the US Midwest

A bomb cyclone is a low pressure system in which the central pressure rapidly drops by at least 24 millibars (mb) in 24 hours or less. On March 12-14 winter storm Ulmer moved over the Midwest and Southeastern United States. In Ulmer the central pressure dropped 26 mb in 16 hours. All time low pressure records were set in Colorado, Texas, and New Mexico. The central pressure dropped to 968 mb on March 13. The extreme pressure gradient in the storm created winds of 100mph or more over in Texas and New Mexico. Blizzard conditions and whiteouts occurred over a wide area. Thunderstorms and tornadoes were widespread during the storm.

An EF 1 tornado hit Dexter, NM. This was the earliest tornado ever recorded in a calendar year in the state of New Mexico. The storm produced damaging winds in Texas as well.. As the storm moved south and east over two days it spawned widespread tornadoes.

Climate change increases the likelihood of severe weather.

Tropical Cyclones in Southeastern Africa

The storm season in the Indian Ocean so far in 2019 has been extensive. There have already been more than the usual number of storms. Mozambique on the southeastern coast of Africa had not experienced a tropical cyclone since satellite monitoring of the earth began. That changed big time this spring when Cyclone Idai came ashore. It turned out to be among the most destructive weather events to occur in Africa, if not the southern hemisphere. The storm had winds measured at over 175 km/h (105 mph) as it reached shore near the port city of Beiria, Mozambique. The storm produced widespread flooding which added to the wind damage. A stretch of land 50km (30mi) long adjacent to the Buzi River was flooded. In places the flood water was six meters (19 1/2 feet ) deep. Parts of Zimbabwe and Malawi were also effected.

The government of Mozambique announced a confirmed death total of 200 and an estimated 100,000 people needed rescuing from the flood waters near Beira. Some of those rescued were without food or drinkable water for as many as three days. Families were split up, some members dying in the flood. The death toll may have exceeded more than 1000. In Zimbabwe a government statement indicated at least 98 died and another 200 missing. Following the storm the president of Mozambique declared three days of mourning.

Only a few weeks later Cyclone Kenneth came ashore in Mozambique It is the first time since records have been kept that two cyclones reached the country in the same season. Again there was extensive flooding.

Our Changing Climate

The big question is whether this event is indicative of climate change or just a matter of chance. In light of storm activity in the Indian Ocean in all probability it is a result of climate change and indicative of things to come.

The Salton Sea: The Accidental Lake

Dead fish line the shores because of high salinity and lack of oxygen

“The Salton Sea was man-made…by accident.”

By Linn Smith

The Salton Sea controversy was generated most recently by the signing of the Colorado Drought Contingency Agreement, which was mandated to be signed by all states bordering the Colorado River by the end of March 2019. These states were mandated to water cuts by the agreement in an attempt to prevent further dropping of water levels.

The Hoover Dam

Why the water cuts? If Lake Mead continues dropping and reaches below 1,050 ft, the Hoover Dam will stop generating power to millions of people. If it continues dropping below 895 ft. it will become a “dead pool”, where water can no longer be piped out to states along the river border. It is today only 40% full at approximately 1,082 ft, thus the federal intervention demand on cutbacks of water usage from all Colorado River border states.

The Imperial Irrigation District, the largest holder of water rights in California, was in line to sign the agreement, but only if the Colorado Contingency Agreement granted water to revive the troubled Salton Sea before signing. California signed anyway and the Salton Sea wasn’t included in the agreement.

The Salton Sea

Old structures fall apart on what was once the shoreline.

History of the Salton Sea

The Salton Sea has a lengthy history and has not been sustainable since its beginning. Sustainability is an avoidance of the depletion of natural resources in order to maintain ecological balance. The Salton Sea doesn’t meet this definition.

The Salton Sea was man-made…by accident. From 1905 to 1907, water poured out of a poorly built system of irrigation ditches meant to divert water from the Colorado River to the dry, arid farm land in Southern California. The water flooded the Salton basin, developing a 400 sq mile lake named the Salton Sea, California’s largest lake. Nicknamed the Salton Riviera in the 1950’s, the lake developed into a tourist destination, with resorts popping up around its edge. The Dept.of Fish and Game stocked it with many types of fish and boaters, yacht clubs and celebrities flocked to its shores.

The Salton Sea

The shoreline has been lost to evaporation and lack of water feeding into it.

The Decline of the Salton Sea

The decline of the Salton Sea began around 1976 with tropical storms, rising salinity due to no fresh water supply to counter evaporation, toxic agricultural runoff and a receding shoreline. Housing prices plummeted! Today, the main attraction is a wildlife refuge on the lake’s shore.

With the recent Colorado Drought Contingency agreement, the Imperial Valley District tried to demand its water rights for the declining sea, stating it has become a health hazard with toxic blowing sand due to agricultural run off, dying fish and abandoned buildings on a shoreline that no longer exists. California signed the Contingency Agreement without the support of the Imperial Valley District, its largest holder of water rights. According to the Washington Post, “The Metropolitan Water District, which serves Los Angeles, essentially wrote Imperial out of the drought plan to prevent delays in implementing it by taking on Imperial’s pledged water contributions to Lake Mead.”

In Support of Hoover Dam and Lake Mead

Was the Salton Sea ever sustainable? We can either support our communities who depend on the Colorado River for electricity and agriculture, or revitalize a dying sea that can’t survive and has little purpose today. With climate change everyone has to give for the greater good and for the survival of future generations.

Earth Hour and Earth Day are Now Global Events

Earth Day, April 22, 2019

This year Earth Day has a theme which is, “Protect Our Species”.

By Dr. John J. Hidore

In the past few years unusual environmental events have changed the public perception of global warming and climate change. Not only have the majority of people now endorsed the fact the warming of the planet is real, but also that something must be done to stop the rapid change to the global climate system.

Politicians around the world, regardless of their political or economic philosophy, are being forced to take action to curb the process. They are taking action because they must deal with the effects of global warming. Whether it is rising sea level, rising global temperatures, more frequent severe storms or changing weather patterns, the problems are real! Mayors of large cities and heads of state are now recognize and realize that something must be done.

Earth Day 2019

Earth Hour

Earth Hour

On Saturday March 30, 2019, a global event took place called Earth Hour. The purpose of the event was to call attention to the rising impact of human activity on the planet. The first Earth Hour was held in Sydney, Australia on March 31, 2007 and organized by the World Wildlife Fund. They asked the people to turn off their lights for one hour from 8:30 to 9:00 pm to call attention to the increasing effects of global warming. It is estimated that more than two million individuals participated.

Support for Earth Hour can be demonstrated by turning off lights at the designated time and/or for individuals, signing a pledge to do your part. Billboards in Times Square, New York and lights on some buildings were dimmed or shut down. Many other cities around the globe also participated. It has also been suggested that there has been more grass roots participation in this event than any other organized event. Next year’s event will be held on March 28 2020.

Earth day 2019

Earth day 2019

Earth Day

The first Earth Day was held on April 22, 1970. This will be the 49th year of the event. Earth Day 2019 promises to be of major significance. This Earth Day, April 22, more national governments, non-governmental organizations, and individuals are expected to take part in scheduled activities than ever before!

This year the event has a theme which is, “Protect Our Species”. The emphasis is going to be on protecting threatened and endangered species. Today humans are responsible for the most rapid rated of extinction of species that has occurred in more than fifty million years. Prior to the impact of humans, species were disappearing at the rate of one to five species each year. The current rate is perhaps a thousand times that. It is estimated that nearly half of all animal species are in decline. Some have labeled it the Sixth Mass Extinction. A mass extinction is defined as an event in which more than half of all species become extinct.

Earth Day 2019

Earth Day 2019

Next year will the 50th anniversary of Earth Day. Plans are already underway to make it a special event!

Climate Change: The Shift in Politics and Public Opinion

“If the Green New Deal isn’t a quick fix, it is creating a conversation.”

Renewable energy

Support sustainable energy

The term Green New Deal, has currently been brought to public attention by Congresswoman, Alexandria Ocasii Cortez. But the term was originally used in the early 2000’s by Van Jones to outline his vision for a program that would birth a “just and green” economy, as written in his book, The Green Collar.

The Changing Public Opinion on Climate Change

Public opinion is changing in support of climate legislation, politicians can no longer put it on the back burner. Seventy per cent of Americans have real concern for our changing climate and have some knowledge of what’s coming down the pipeline in our future. Most people have also experienced some form of extreme weather conditions in the past several years.

The Green New Deal

If the Green New Deal isn’t a quick fix, it is creating a conversation and parts of the proposal are gaining support from both Democrats and Republicans.” An article on climate change in the recent issue of Time Magazine states, “The outcome of the debate will go a long way towards determining if humanity can avoid the most catastrophic consequences of a rapidly warming world….the science is damning and the clock is ticking!”

Renewable Energy: Hatch, New Mexico

“The systems are best for high and dry climates, which makes Hatch an optimal location.”

As a resident of New Mexico for 6 years, I have long known the value of Hatch green chili…the Best in the West! But the past several years I have traveled Hwy 26, a lonely stretch of road through seemingly baron land just west of Hatch, passing massive wind and solar fields.

Solar Power

According to VillageofHatch.org here is the data on the impressive energy produced by these solar fields, plus pictures I was able to snap along my route recently:

“The Hatch Solar Energy Center consists of 84 Amonix 60-kW systems on 41 acres of land. The platform and panels are each 50 feet wide and 55 feet high tall. Each panel is made up of three different photovoltaic materials in a single cell so they extract more energy from the range of wavelengths in sunlight. Dual-axis tracking systems maximize energy production throughout the day by allowing the CPV systems to follow the sun. The systems are best for high and dry climates, which makes Hatch an optimal location. The systems require no water in power production, use land better, and produce more energy per acre than any other solar technology— equivalent of planting 3,500 trees every year it operates.”

Wind Power

The Macho Spring windfarm is nearby.

Wind Turbines

Along my route I also passed a train carrying at least 30 wind turbine blades…the trip was a visual feast for my “build it green” eyes!

And, while you’re on the drive, stop at Sparky’s in Hatch and get some green chili lemonade, it’s a treat your taste buds won’t soon forget!

Happy Trails!

On Population Growth

“The momentum for an increasing population seems to be difficult to change.”

By Dr. John J. Hidore

March 17, 2019—–During the earliest stage of modern humans the human species was struggling with the environment. They were just beginning to use stone tools. The size of the population was limited by the amount of wild food that could be gathered or caught. When food was scarce the population died back, and when it was plentiful the population expanded.

Diseases due to technological advances began at an early time. Sinusitis is a disease that irritates the nose as a result of breathing damp, smoky, or dusty air, such as was often found in inhabited caves. Evidence of sinusitis has been detected in skulls dating well back into the paleolithic. Only limited numbers of human lives were lost from storms and other short lived events as the population was small and widely scattered.

Overpopulaton

Overpopulation and turmoil leads to current migration patterns.

During the first 500,000 thousand years the population growth was slow. Birth rates were high, perhaps between 38 to 42 per thousand. The death rate was also very high, perhaps between 35 to38 per thousand. Evidence indicates that infant mortality was high and average life span was around 30 years.

Although life was difficult for hominoids during this time, the human species triumphed. Charles Darwin stated the case for these early people. “Man, in the rudest form in which he now exists, is the most dominant animal that has appeared on earth. He has spread more widely than any other highly organized species, and all others have yielded before him.” (1871)

Overpopulation and wallstreet

Does organized religion support overpopulation?

Current and projected Growth

The global population numbers began to grow and are now growing faster than at any time in history. We are now adding about 224,000 people per day to the planet. This adds 82,000,000 people to the planet each year. That annual increase is the same as adding the population of the United States to the planet every three to four years.

What is astonishing in the growth data is how fast the rate of growth has been increasing. It took hundreds of thousands of years for the first billion to be reached in about 1800. The time it has taken for adding each billion has dropped rapidly. The last billion was added in just 12 years from 1999 to 2011. At the beginning of 2019 global population stood at about seven billion. The key element in driving population growth is changing technology which has increased the global food supply.

Some estimates of early human population size:

125,000 1 million years ago
1-5 million 11,000 B.C
50 million 3,000 B.C
500 million 1,500 A.D.

Adding the billions Time Span for the growth:

1 billion 1800 200,000 to a million years
2 billion 1930 130 years
3 billion 1960 30 years
4 billion 1974 14 years
5 billion 1987 13 years
6 billion 1999 12 years
7 Billion 2011 12 years
8 Billion 2023-2025 12-14years

The human population reached its highest annual growth rate of about 2 percent per year, in the early 1970s. The growth rate in 2018 was around 1.1 percent. While the rate has dropped the absolute number of humans added to the planet each year continues to be greater than in the past. In mid-2019 the total population is estimated to reach about 7.7 billion.

Carrying Capacity and overpopulation

What is Carrying Capacity?

Region Growth

Today the fastest-growing countries are the developing countries. Many of the nations with the highest growth rates are in Africa and southwest Asia. China has the largest population of any country. However, India, which has a smaller population than China but has a higher growth rate, is adding 1/3 more people each year than is China. The UN projects India to surpass China as the most populous country in the world about the year 2028. At that time both countries will have a population of about 1.45 billion. China’s population will begin to stabilize near that time and India’ will continue to grow for some time. Most of the growth will be in developing countries with more than half in Africa. Population in Sub-Saharan Africa is projected to double from the 2010 population of 0.86 to 1.96 billion in 2050.

Are there enough resources for overpopulation?

With climate change will there be enough resources for all?

Prognosis

The next billion people added to the earth will want and expect food, clothing, shelter, and some means of employment. How are these needs to be met? There are already a billion people with some degree of malnutrition. Most of the population supports themselves from agriculture. All good and even marginal land is already occupied, and much productive land is being removed from agriculture due to erosion and general depletion. How are these agriculturists going to find employment? These are critical issues.

The momentum for an increasing population seems to be difficult to change. Global business thrives on population growth. It seems the options are limited. Either the human species understands what is taking place and mandates a change, or these trends will continue until some unpredictable apocalypse eliminates a substantial portion of the people living at the time.

The world’s increasing population!
