Critical impacts such as malnutrition, lack of food supply, unemployment, lack of education, destruction of ecosystem, poverty, lack of housing & uncontrollable diseases indicate that there is overpopulation, regardless of the carrying capacity of ecosystem. The third way is population size and resource use to their environmental consequences (Addison,1994). The world is over populated if the environment is damaged by factors like pollution and habitat destruction on large scale.
"One cause that affect the amount of food produced is because the amount of land available for growing crops".(Persell, 1990). Due to overpopulation the supply for food is affected.

In the long run, overusing those areas may cause them to dry up and also become unfit for farming.
