What is the cause of overpopulation?
Overpopulation occurs when a species’ population exceeds the carrying capacity of its ecological niche. It can result from an increase in births (fertility rate), a decline in the mortality rate, an increase in immigration, or an unsustainable biome and depletion of resources.
Will the human population eventually outgrow the earth’s ability to sustain it?
Understanding Carrying Capacity Human population, now over 7 billion, cannot continue to grow indefinitely. There are limits to the life-sustaining resources earth can provide us. … Carrying capacity is the maximum number of a species an environment can support indefinitely.
What happens when Earth reaches carrying capacity?
Real population growth This anticipated leveling off signals a harsh biological reality: Human population is being curtailed by the Earth’s carrying capacity, the population at which premature death by starvation and disease balances the birth rate.

Can humans increase their carrying capacity?
The carrying capacity of the planet for humans has increased over time, especially with the development of agriculture and other technologies. The industrial revolution has only artificially increased our carrying capacity since it is based on the use of fossil resources, and thus is not indefinitely sustainable.
