It is called a limiting factor. It limits the population.
Logistic Model
the number of hamburgers available from McDonalds greatly limits the population.
Population growth rate is a measure that helps determine how quickly a population increases within an ecosystem. It is influenced by factors like birth rate, death rate, immigration, and emigration. Understanding the population growth rate is crucial for studying ecosystem dynamics and implementing conservation strategies.
The short answer is that population growth restricts the forest in at least two ways: more people need more land to live on, and they need more lumber to build with.

Food chain, habitat resources and limited food availability restricts the growth of animals which do not implement in case of humans.
When exotic species are introduced into a new ecosystem, they often don't encounter the same factors that controlled the exotic species population or growth that was in the original ecosystem.
Rapid human population growth.
We dwindle it away at a faster rate than it can reproduce, but with such an abundance, the masses do not care.
For the next hundreds years: wars, pollution, population growth, AIDS, resource depletion, hunger, etc.
