What do you think will happen if the human population reaches its carrying capacity?
When we will reach our carrying capacity (I hope we will not see anytime), water, food, shelter and resources will be very limited (per capita). People will be unhappy due to hunger (or maybe due to other reasons). The Earth will be fine but will have no trees and a lot of polluted water in the ocean.
Will humans go extinct due to overpopulation?
(PhysOrg.com) — Eminent Australian scientist Professor Frank Fenner, who helped to wipe out smallpox, predicts humans will probably be extinct within 100 years, because of overpopulation, environmental destruction and climate change.
Why is it difficult to predict the growth of Earth’s human population?
exponential population growth and development leads to faster depletion of resources, population grows exponentially, why population prediction is difficult, population is not evenly distributed throughout the world.
Why is population growth bad for the environment?
As we harness more of the planet’s resources to support our increasing numbers, we continue to see major environmental changes. An increasing population challenges our ability both to live sustainably as a species and mitigate human-driven climate change.
Can Earth sustain a population of 100 trillion humans?
If you include 100 trillion humans worth of human technology (roughly 200–200,000,000 times as much technological progress as has occurred so far, depending on what kind of “trillion” you mean), Earth can probably be made to sustain a population of a few hundred of the larger kind of trillion.
Can humanity live from the returns of the Earth’s natural capital?
Notwithstanding the huge losses of human lives during the wars in the twentieth century the world population has increased that very century from 1.6 to 6 billion. The limits of the sustainable regeneration power of the earth have been surpassed for the first time. Untill then humanity could live from the returns of the earth’s natural capital.
When will the world’s population fall back to its present size?
The study also found that implementing contentious population control measures such as a worldwide one-child policy, results in a population that wouldn’t fall back to present-day size until the end of the century.
