An ecosystem is a geographically specified system of organisms,
including humans, their environment, and the processes
that control their dynamics. The ecosystem approach
is a tool which provides a framework that can be used
to implement the objectives of the Convention on Biological
Diversity, including the work on, inter alia, protected
areas and ecological networks.

on a scale of A to G, where an A-rated boiler is 90%
efficient and a G rated boiler is below 70% efficient.
