Question

What are the effects of increase in population on the ecosystem?

Answer 1

an increase in population will skew the distribution of carbon in favor of the more populous species.  Unless they are effectively crowding each other, they will be more efficient in reproducing (if sexual).

A larger population will also have a more robust genetic pool, being less susceptible to inbreeding.

Answer 2

Effects of increasing population  on environment:

1).For growing needs they spoil the ecological blance,by exploiting the too much resources.

2).Increased number of humans, increase the environmental pollution by cutting trees for their survival and accommodation.

3)They make the survival difficult for lower grade organisms.

4).for the above exploitation,bad or harsh environmental changes occur which shows its effect on increased population only.
