Destroying our habitat

Overpopulation: Environmental and Social problems
by Neville 2014

Human population is growing. We are now adding about 220,000 per day. The list of problems this is causing is a long one. It includes shortages of all our resources, war and social conflict, limits on personal freedom, overcrowding and the health and survival of other species.

Many basic resources are strained by our current population:

Food: one billion people, one out of every seven people alive, go to bed hungry.Every day, 25,000 people die of malnutrition and hunger-related diseases. Almost 18,000 of them are children under 5 years old. Food production and distribution could catch up if our population stopped growing and dropped to a sustainable level.

Water Shortages: About one billion people lack access to sufficient water for consumption, agriculture and sanitation. Aquifers are being depleted faster than they can be replenished. Melting glaciers threaten the water supply for billions.

Air quality: Pollution from smokestack In many regions of the country, childhood asthma rates have risen dramatically in the past 20 years. The problems are not limited to the industrialized countries with their automobiles and factories. Children in undeveloped countries, where people depend on burning wood and dung for their heat and cooking, are also at risk.

Oil and gas underpin cheap and fast transportation that today’s huge population depends on. There is a finite amount of these fossil fuels in the Earth, and we have already extracted the easy-pickings in much of the world.

Oil Disasters The cause of the oil-spill disaster in the Gulf is the unprecedented rise in population. If we had only 150 million people in the country, we would not be rushing to drill wells one mile deep in the ocean before we have developed safe technologies to do so.

Wood and Dung Fuel Half the World’s population relies on burning wood and dung for cooking and for heating. More and more people live in these regions and have to travel further each day to collect wood, and are often exposed to hardship and danger.

The Ozone Layer of the atmosphere no longer protects us as well from the harmful ultraviolet (UV) rays of the sun. The ozone layer is a region of concentrated molecules of a form of oxygen (O3) high above the earth. Without it there would be no life as we know it here because the UV rays from the sun can be very harmful. Currently the layer is being destroyed at a rate of about 4% per decade.

The World’s forests are another resource that is strained by our growing population. Not only are they a source of fuel and building material, recent research has focused on forests’ ability to sequester greenhouse gases and protect us from global warming.

Our Oceans ability to breed the fish we eat, to sequester carbon, and to replenish the air is diminished. In the 50’s and 60’s, Florida was a by-word for the abundance of the sea. Now even some of the “trash fish” of that era are too rare to fish commercially or recreationally.

Topsoil itself has limits: most people don’t realize that in many regions good growing soil is limited to the top 6 inches of topsoil and that heavy crop growing has depleted it. Two inches of soil takes a thousand years to develop on a forest floor.

Social Problems

Overcrowding Rats that were put in overcrowded cages suffer many physical and behavioral problems. The same has been shown for Sitka Deer and for mice. This is happening to people too.

One recent study from U.C.Irvine found that less densely packed people are friendlier towards their neighbors. One specific finding was, “For every 10 percent decrease in population density, the likelihood of residents talking to their neighbors at least once a week jumps by 10 percent. And involvement in hobby-oriented clubs increases even more significantly — by 15 percent for every 10 percent decline in density.”

Conflicts and Wars: Some of the most brutal and persistent conflicts and full-out wars of the past decades include the stresses of overpopulation and conflict over resources.

Rwanda Genocide: “The Hutu leaders that planned and carried out the genocide against the Tutsis in 1994 relied strongly on heavily armed militias who were recruited primarily from the unemployed. These were the people who had insufficient land to establish and support a family of their own and little prospect of finding jobs outside agriculture. Their lack of hope for the future and low self esteem were channeled by the extremists into an orgy of violence against those who supposedly were to blame for these misfortunes.”

The Jordan River, Jordan River which passes through Syria, Jordan, the West Bank and Israel. Researchers report that most of the 37 actual military conflicts over water since 1950 took place between Israel and its Arab neighbors over the Jordan River and its tributaries, which supply millions of people with water for drinking, bathing, and farming. These are desert regions and the limits on water should guide the population policies of the nations involved.

Pakistan and India are especially sensitive since both highly-populated, fast growing countries have nuclear weapons. Pakistan’s major water source is the glacial waters of the Indus river, which originates in Indian territory. [article on Pakistan’s water] [archive]

Democracy We tend to think that Democracy offers us freedom of choice, but in the last 40 years, we have had little effective input into most of the political decisions that affect our lives.


A short essay on overpopulation and its effect on American Democracy
written by:Albert A. Bartlett Professor Emeritus Department of Physics University of Colorado at Boulder, Albert.Bartlett@Colorado.EDU

Do we have a truly Democratic system when most of us never even meet our Representatives at the various levels of Government? Even our State and City representatives probably don’t know us and our views about the laws and regulations they pass. The only people most of them see on a regular basis are the lobbyists, who consequently have a disproportionately large influence on those laws and regulations.

Democracy and Optimum Population Size: 2500 years ago, Aristotle considered the best size for a city and concluded that a large increase in population would bring, “certain poverty on the citizenry, and poverty is the cause of sedition and evil.” He considered that a city of over 100,000 people would exclude most citizens from a voice in government.

To get an idea of what the founders of the United States had in mind for our representative Democracy, at the low end, the Constitution says (Article 1, Section 2) that a Representative to the House should represent a minimum of 30,000 people. When the Constitution was written, the United States had a total population of around 2.5 million, and the Constitution allocated 65 Representatives to the 13 states. So each Representative of “the People’s House” had about 38,500 constituents. Currently each Representative has 712,650 constituents. It’s really a form of irony today to call it “the People’s House” when only wealthy donors and paid lobbyists really have the ear of your “representatives.” What we have now is not Democracy in the sense intended by the country’s founders.

Health and Population density: Viruses spread faster in denser populations, which enables deadly mutations to continue and virus mutations to jump from animal to human populations.

AIDS is one of these. What’s changed is in the past you had smaller human populations; viruses would infect them and go extinct. Viruses actually need population density as fuel.


The cost of housing is rising significantly. Usually, the denser the city, the higher the cost of housing and taxes.

The length of your commute: the average American heavy traffic spends over 100 hours per year commuting to and from work. Not only does this needlessly waste energy but it wastes our time.

Recreation: the distance you must travel to enjoy natural open spaces. In his 2005 book: “Last Child in the Woods“, Richard Louv introduced the term “Nature deficit disorder” to identify a phenomenon we all knew existed but couldn’t quite articulate. Not only adults, but especially our children, need easy casual access to natural environments.

Parking Developers with a complicit city council build without proper parking as more people are brought into the country.Unfortunately for the residents of the city, the outcome for many local businesses has been termination. We certainly try our best to support local businesses and would strongly prefer to shop where we can see the merchandise and talk to an informed salesperson, but we won’t fruitlessly try to park, circle the block, and pay to park in a lot 3 blocks from the store. It’s much faster and easier for most residents over the age of 45 to go online and have goods delivered.

The never-ending new buildings block our views, our light and our air. Twenty years ago, my town had a sense of space, with views of hills and water from most streets even downtown and nearby. But thanks to a few developers’ and planners’ emphasis on “growth”, many entire blocks are now walled in with 5 and 6 story behemoths.

Many of us bemoan these losses and have felt helpless in the face of the financial powers backing these developments. However, if these developers had to fully pay the rest of us for the loss of our amenities, they might slow down. There is a way to put a monetary value on the losses the community has suffered. In an appraisal, a residence with a view and a spacious surrounding is more valuable than one that is boxed in between high-rise buildings. In my region that might add $100,000-$200,000 (or more) to the value of a house. If 2 people spend perhaps 10 waking hours a day there and own the house for 5 years, that works out to about 36,500 waking hours. That’s $2.74 – $5.48 per hour. Let’s call it $3.00 per hour for the sake of this very rough estimate.Of course, no one person spends 10 hours a day at one spot on a city street, but many hundreds (or thousands) of people do pass by. In my town of about 100,000 people, perhaps 100 cars/hour and 100 pedestrians per hour pass through the downtown blocks. (More in the daytime and fewer at night.) The buildings which are being built take up an average of about half a block apiece. By rough estimate, it takes a car 10 seconds to pass, and a pedestrian one minute. That works out to 46.7 person-hours/day that someone is being deprived of light and air and a sense of spaciousness. At $3.00 per hour, that’s $140 a day or a little over $51,000 per year. These buildings may last 40-50 years, making the total value of the lost amenity $2,040,000-$2,550,000.

The problem so far has been that when an individual buys or sells a single house, they control what they are willing to spend or what they can ask for that asset. But when a building is built in town, the 4,000 or 5,000 people per day who pass by it are not compensated for their loss. However, that is what government can do, and we suggest permitting and licensing fees to compensate us for our losses. The city can charge this to the developer, and apply the resulting city income to mitigating these losses by purchasing other sites & the development rights to other sites.

These are, of course, very rough estimates, and a permitting law would require better estimation of the current value of spaciousness in the community, and of the foot and vehicle traffic past any proposed building site.

Personal Freedom

As the problems of higher population density become worse, there are more and more restrictions placed on our freedoms. They are necessary only in order to accommodate the larger population that our policies are encouraging.

Limits on water consumption. California is mandating that residential users cut back 20% on water consumption. At the same time they mandate that Cities build more and more housing. That is severely mistaken priorities on the part of our non-representatives.

Limits on driving London charges people to drive into downtown. Annually, politicians in New York repeatedly propose doing the same thing.

Limits on travel: Traffic and congestion themselves put limits on our freedom to travel when and where we please. Cities that are overly crowded are not good places to go shopping, for meals or entertainments, because it is overly difficult to get there and park.

Limits on fireplaces. Laws are passed, neighbors snitch on neighbors, and one more of life’s little pleasures is lost to increasing housing density.

Restricting what people can do on their land: In rural areas, people are freer to build what they want and do what they want on their own land. When people are packed in close together, our actions impinge much more directly on our neighbors and more restrictions must be enacted.

Other species

Extinction: We are in the midst of one of the greatest extinctions of other species in the history of the planet. The last one of this magnitude was over 60 million years ago, when the dinosaurs became extinct. Yep, we’re the cause of this one, as we either kill them off outright, or cover over their living space with houses, roads and development. Did God give us dominion over this beautiful garden that we might destroy it, or that we might take care of the glory of creation? It’s our choice.

Habitat destruction: Our exploding population in the U.S. is converting about 1.2 million acres of rural land per year to subdivisions, malls, workplaces, roads, parking lots, resorts and the like. The rural area lost to development between 1982 and 1997 is about equal to the entire land mass of Maine and New Hampshire combined. (Approximately 39,000 square miles or 25 million acres)

Habitat Fragmentation in the Indiana Dunes Habitat Fragmentation Not only is habitat being built over, it is also being divided into ever-smaller pieces. Habitat fragmentation reduces species richness and diversity, by isolating a species population into subpopulations that may be too near the minimum viable population size, and so die off in each fragment. A fundamental finding of ecology is the species-area relationship, that the size of a habitat is a primary determinant of the number of species in that habitat.

Some critics point out that we can accommodate more people without so much habitat loss and habitat fragmentation if we all live in cities or densely packed developments. This is certainly true, but the point we emphasize here at is that this is not what most people want.Jaguar Many people, given the choice, prefer to live on larger parcels. Many people want larger yards and gardens, and get-away cabins where you can’t see your neighbors. And we can continue to have these amenities if we re-energize a vision of a smaller, more sustainable population.

Does a growing population really help any of us?

These are some of the ways our growing population is impinging on our quality of life, and in many regions of the Globe, life itself.It’s a long list, and more could be added. As some point out, these problems are not entirely the result of overpopulation. We could consume less, we could use resources more efficiently, and we could distribute them in ways that would not deprive so many of access to the basics. But there is no doubt that these these problems could be solved more easily if we don’t add 3 billion or 5 billion, or many many more people to our lovely planet.

And coverage of the link is almost nonexistent in most media outlets, even those covering the environmental and social problems that ensue. This is the most basic question that an intelligent species could ask: What is the right number of us to be living on our fair planet?

Instead of saying there is nothing we can do about it, just accommodating to the imagined inevitability of it, shouldn’t we be asking “Does a growing population really help any of us?”

It’s hard to think of a current problem which will be solved more easily by adding another 2.3 billion people to our population.

Rather than asking how we might accommodate additional billions of people, we could be asking:

Will the addition of another 2.3 billion people competing for land and resources do anything to improve the lives of people living now?
Will the lives of those 2.3 billion additional people be anything as enjoyable, prosperous, and free as those of their parents?
How can we effectively and non-invasively control population growth?

The answer to that last question is easy
