What are some examples of carrying capacity?

With respect to Carrying Capacity, an instance of dieback transpired in Ireland following the destruction of the potato crop in 1845 due to a fungal infection. During this potato famine, approximately 1 million individuals perished and 3 million migrated abroad.

People tend to commit suicide more frequently in populated areas (my personal opinion). In Africa (across many different regions), where the population growth rate is high, people tend to migrate abroad because the continent does not provide them with enough food, shelter, or suitable living conditions.

Here are a few carrying capacity examples.

Some examples of carrying capacity include the number of fish that a lake can support, the maximum population of deer that a forest can sustain, and the maximum number of people that an island can accommodate without depleting its resources.
