Population Growth the Impact on the Environment


For centuries, scientists have predicted that the the human race is closing in on the carrying capacity of the planet Earth to provide for humans. The more people who populate the planet, the more goods will be consumed, the more food will be required to be grown, and the more electricity will be utilized. All of these small parts of a person’s life will affect the environment of the planet. It is important to consider all of these complex problems as the current estimated human population by 2100 reaches twelve billion.


    • The number one threat to the world’s freshwater environmental ecosystems is human population growth. According to the Clean Water Action Council, most of the world’s ocean fisheries are at maximum peak capacities in fish production. In addition, 434 million people are either faced with water stress or scarcity today. By 2025, it is estimated that up to 3.1 billion people may be living in an environment with either water-scarcity or water-stress. As the world’s population grows, the amount of freshwater available for each person will decrease, as one of the world’s most precious resources for life to flourish and sustain itself. Between 1900 and 1995, water consumption rose sixfold, which is more than twice the rate of population growth during that same time frame.

Fossil Fuels

    • As the world’s population grows, more electricity and fossil fuels will need to be consumed in order to keep up with the demand of both developed and rapidly developed nations. It is mainly the rapidly developing countries–which are developing more up-to-date industries but also which have been experiencing larger growth rates than developed countries–that will have the most environmental impact on the world in the future. Although no one knows for sure, scientists expect that fossil fuels for automobiles are projected to run out at some point in the next fifty to seventy-five years, requiring all humans to develop alternative forms of transportation. Additionally, other fossil fuels, such as burning coal for electricity, will continue to increase the amount of greenhouse gases in the atmosphere. According to Climate Interactive, if the world’s population continues to grow and world governments do not change policies and regulations regarding the production of greenhouse gases, the global climate will rise nearly five degrees Celsius by 2100, flooding most coastal cities, including Washington, D.C., and most of Florida and Louisiana.

Public Health

    • World-wide public health is already a serious issue, with the promise of escalating risks as the world population rises. Unclean water, lack of sanitation, and air pollution kill more than 15 million people per year. That figure will rise dramatically as population growth continues along its projected rates. Currently, sixty-four out of one hundred and five developing countries have populations that are growing more quickly than the current growth of food supplies.

Forest Cover

    • Currently, nearly half of the original forest cover has already been lost worldwide. More than 16 million hectares are cleared annually. As world populations grow, there will not only be an increased need for resources to be extracted from those forests but the space that the forest occupies as well. Current demand already exceeds the limits of sustainable yield by more than 25 percent worldwide. Forest cover is linked not only to biodiversity issues but also to the preservation of freshwater ecosystems, groundwater supplies, and reducing the amount of greenhouse gases, which cause climate change.


    • Many political scientists, economists, and military scholars predict that future wars will be fought over natural resources. Politics and international relations will be governed by the availability of resources in and between nations. It is already apparent that the current systems of this world are not compatible with the predicted population growth. Water is already scarce in many parts of the world, as is food. Fossil fuels are limited, non-renewable resources in and of themselves. Individuals, communities, nations, and groups of nations will have to work together and independently of each other to pursue a more sustainable lifestyle before it is too late.

    Tone is correct but the projections are the usual goal seeking per status quo growth targets. The results are likely much worse and manifested much sooner. The next few years are likely a time of inflections not witness by any of us at anytime in our lives. The world is going to quit fitting our usual perceptions we have been habituated to. Call these changes surreal because denial will meet reality and result in dysfunction and the irrational. We are truly in uncharted waters with no rudder.

    The insidious underlying problem that begets all other problems. Also, the one that has gotten the least attention. No better example of humanities colossal failure to live in a sustainable manner.

    The purpose of life is to acquire energy and procreate. This is the primary genetic imperative. Even though some humans have realized this, we as a species can’t go against our programming.

    So when we reach peak-people, there won’t be any forests or fresh water. Then everybody starve and have big wars lowering population. So after peak-people the population falls, but nobody is safe against being killed. Coming soon to a planet near you.

    “Did the human RNA have an enjoyable week toiling in their work cells? Were they productive? How much money/reward did they earn? Were they dreaming of their next stop on the money/reward express – a trip abroad, granite counter tops, a new toy from Best Buy or just a quiet evening watching the incessant coverage of the wannabe Presidential candidates whose manifest destiny is to deliver more growth and jobs to the functioning cancer masses. As if we haven’t grown enough already, the crowd cries out for more and the politicians, like glucose plum fairies, prime their brains with hopeful expectation. How many election cycles of the hope and change bullshit will we have to endure before the populace figures out that the glucose plum tree is dying? As economic growth comes to a halt it will be interesting to see who gets the remaining sugar plums. Will it be the working man, the military-industrial complex, the medical/insurance industry, the youngsters or the oldsters?”

  6. onlooker on Sun, 27th Mar 2016 2:16 pm 

    The mismatch between the promises and the realities or ability to deliver on those promises is becoming an ever widening chasm. I believe the military-industrial complex will get the remaining sugar plums just to keep the power structure and military functioning.

    Very strong points in this article which interestingly are not any of the hot topics in this current election cycle and yet they need to be addressed. The question is why are Americans so oblivious to the crisis that humanity faces and refuse to seriously debate the issues.
    The American tends to be a person that lives in a state of suspended animation between perceived images of a glorious past where we have deified the generation that fought for independence from Great Britain and if we return to those “values” that they stood for our greatness will return. All we have to do is build wall, return production to the country, and get rid of all those non WASPS that deteriorate our values.
    But as much as they look to the past they see a brighter future, a future that is dictated by the fictitious images of Hollywood that capture technology triumphant over all these small problems.
    But the main problem is that the American is not about to give up a lifestyle in which they have grown accustomed to and that can only mean more wars and more suppression of the less developed world to fulfill our insatiable appetite for this planets finite resources. Bigger houses, bigger SUV’s, bigger TV’s, and smarter phones are what drive us. And soon these will all pass into history, if there is future history to be written.

    Population growth is not uniform across the globe. Likewise, shortages of water, health resources, natural resources, energy resources, etc. are not uniform across the globe.

    Doom will be localized and to the extent that it slows population growth, it will be self-limiting.

    Things are always more complex than your average low-rent analyst wants to believe.

  9. JuanP on Sun, 27th Mar 2016 5:58 pm 

    Argosy, This is the only planet we’ve got, and it has only one biosphere. You are an ignorant fool who thinks himself a wise man. Were you born in the USA by any chance? There are many ignorant fools like you here, more than anywhere else I’ve been to. There is no safe place. Please have children, the world needs more retards like you! LOL!

  10. makati1 on Sun, 27th Mar 2016 7:21 pm 

    sidzepp, you are spot on. Americans are living on past glory, which, even than was mostly propaganda fed to them from birth. Reality’s 2X4 is going to hit them in the face very soon and it will take out all out of them the first year.

    12 billion is just taking a ruler and extending the current line, not reality. We will never reach 9 billion. Maybe not even 8. WW3 will happen and it will not be just like WW2. Well, maybe the end of WW2 when we nuked Japan only this time it will also be American cities under the big mushroom.

  11. makati1 on Sun, 27th Mar 2016 7:35 pm 

    JuanP, there will be no place totally safe, I agree. There will be a lot of places where the decline will be more gradual and, barring a nuclear exchange, will take generations to get drastic. The more developed a country is, the more likely it will be hit the hardest. Water, oxygen/air and food are the only necessities we have. All others are wants.

    Comparing the Us, which I know, and the Philippines, which I am coming to know, I still think Filipinos have a greater chance of pulling thru the bottle neck than Americans. Sure, a percentage of the population here will die, but it will be a much smaller percentage than in America. Ditto for other “undeveloped” areas of the world.

    Yes, we only have one planet, but not all parts of it are equal. The cities are doomed everywhere but the countryside is not. Weather patterns will change. Old rivers will dry up. New rivers will form. Polar ice may be seasonal in the north and much less in the south. Earthquakes, hurricanes, tornadoes, floods, droughts, diseases. ALL will increase in strength and frequency. It will be a challenge to survive. Again, those who do will be the ones who started closer to the mark than those who had it all.

    Pass the popcorn.

    More of the same facts and projections.  And more of the same liberal answers from the usual crowd:  exterminate Whitey, and everything will become paradise.  Few seem to acknowledge the fact that Whitey is rapidly waning in numbers, while the non-Whites are exploding exponentially.  Because White demographics are diminishing, the genosuicidal elites who run the U.S. and other formerly White countries are accelerating their importation of muds.  They believe that importing sheer numbers of diseased dross is the only way they can maintain their election-based power.  Hence the refusal to build a wall against Mexico.  Hence the West European decision to become non-European (thereby delighting the Left) by accepting a vast invasion from unwhite trashlands and to cover up their national suicides with fraud, lies and media propaganda.  The one and only fear of the elites is White “racism” — that is, any White refusal to die.

    Given the stupefying corruption by establishment megalomaniacs and the bribe-ocracy in general, it now looks like there is no way to stop the dark hordes from overwhelming civilization and putting an end to intelligent life on the planet.  Because any White strategy to survive would be racist.

  14. PracticalMaina on Mon, 28th Mar 2016 10:37 am 

    I think the point is, whitey should ride a bike, like they do in Europe, and eat less beef. You’re colon will thank you.

    Douchy, what good would it do to have a white movement at this point? White culture is all about exploitation. It’s been ingrained in us for the last 500 years. Haven’t you noticed? Haven’t you noticed that it’s elite whites in your own country who are impoverishing everyone else? You looking for a reset? Get rid of everyone except whites and start the game over? Too late fuck wad – the entire species is on it’s way out and none of your pitiful race pandering will change it. The white man peaked awhile back and will never ever regain what was lost. EVER. Like I said before, keep up the snivelling and baby moaning – it makes me happy to see you suffer.

    The Arctic sets yet another record low maximum extent

    “I’ve never seen such a warm, crazy winter in the Arctic,” said NSIDC director Mark Serreze. “The heat was relentless.” Air temperatures over the Arctic Ocean for the months of December, January and February were 2 to 6 degrees Celsius (4 to 11 degrees Fahrenheit) above average in nearly every region.”

    ” Systems ecologists such as Paul Erlich, David Pimentel and others estimate the U.S. can support about 100 million people without fossil fuels.”

    I think that number is high. It will likely be half of that or less. Less than 5% of Americans are actually farmers today. And they are old. You do not learn farming in a few months or even years. Especially real farming without oil. Otherwise, it is a long, but worthwhile read.

    Great Barrier Reef bleaching worse than first thought

    “An aerial survey of the northern Great Barrier Reef has shown that 95 per cent of the reefs are now severely bleached – far worse than previously thought.

    Professor Terry Hughes, a coral reef expert based at James Cook University in Townsville who led the survey team, said the situation is now critical.

    “This will change for Great Barrier Reef forever,” Professor Hughes told the ABC’s 7.30.”

    The worlds poorest people are having the most children. They have not figured out the connection between their poverty and family size. Endless population growth is not sustainable.
    If you can not provide for yourself you can not provide for a child.

    Too many people……….create too much pollution and demand too many resources….

    China made great progress in moving its people out of poverty…….one reason was slowing population growth…..

    If you can not provide for yourself you can not provide for a child.

    CLIMATE CHANGE, declining fish stocks, droughts, floods, air water and land pollution, poverty, water and food shortages all stem from the worlds worst environmental problem……. OVER POPULATION.

    Yet the world adds 80 million more mouths to feed, clothe, house and provide energy and water for every year… this is unsustainable… and is a big part of the Climate Change problem
