What is a fish without a river? What is a bird without a tree to nest in? What is an Endangered Species Act without any enforcement mechanism to ensure their habitat is protected? It is nothing.
I must stress, basically, the very fact that we do have orangutan rehabilitation means that we have failed to do what is really important, and that is rescue the wild orangutan in its habitat.
Habitat for wildlife is continually shrinking - I can at least provide a way station.
I married a woman from New Orleans, so I had family here. Post-Katrina, I had a number of friends call me up and say they wanted to do something to help the community - not just Habitat for Humanity or Red Cross, we've done that, but what can we do for the community.
The limits of sensory evolution in fish are defined very largely by their habitat. Water is physically supportive, carries some kinds of odour well, and is kind to sound - letting it travel several times faster than air will allow, but it inhibits other more personal kinds of communication.
