Answer:
Carrying Capacity is very important for today as well as for the future.
Explanation:
Carrying Capacity refers to the maximum population of a particular organism that a specific environment can hold. In each and every environment, there are different population of organisms present due to the availability of resources such as food, water and space for living. If these resources are present in large amount then the population of organism will be higher but if these resources are limited, then the population will be lower. Carrying Capacity is also important for the future because with the passage of time, population of human increases which destroy the forests because human requires area for living. So for cutting of forests, the animals migrated to other areas and sometimes die due to no space available for them.
