Sustainable ecosystems are at a balance between the rates of resource removal and replacement.Amazon Book Order Palumbi

Ecosystems remain productive when used sustainably. Sustainable ecosystems are able to continually create resources without eroding the health of the ecosystem. Taking resources faster than they are made, or when their destruction exceeds regrowth, decays ecosystem health and makes it less productive. Several elements interact to determine ecosystem sustainablity.

Why preserve sustainability?
Ecosystems are sustainable when we balance the rates of removal and replacement. Sustainable ecosystems provide resources and services people rely on, such as:
-food and other income
-maintaining ecosystem health
-cultural needs
