Summary Introduction
Introduction:
A community involves many species that depend on the special type of species, termed as a keystone species. Some ecologists use the strategy of removing each species artificially to identify the keystone species. For example, sea stars that is a keystone species act as predators in tide pools.

- At any point in time, a number of environmental objectives must be met with a limited amount of economic resources. This means that once an environmental problem is identified, they have to be prioritized.
