Pros and cons of saving endangered species

The conservation of endangered species is important for humans as well. A well-balanced ecosystem purifies the environment, giving us clean air to breathe, a healthy water system to support diverse marine life, and arable land for agricultural production.

Explanation:

The health of an ecosystem is maintained by its plants and animals. When species become endangered, it is a sign of an ecosystem's imbalance. This balance is difficult to maintain: the loss of one species often triggers the loss of others ... By saving endangered species, we are ultimately saving ourselves.
