"...pollution, biodiversity loss, waste, resource use, and habitat protection used to be the focus for enviros, but they're less visible of late. Some argue that these challenges can all be addressed under the umbrella of climate change, as it's a huge topic that touches just about everything else."

Commenting on the above, I think most of us understand we are in a web where, indeed, everything is connected. However, connecting climate change to over-population (both crucial environmental issues) probably doesn't begin to get us moving on funds for internal and international health and family planning funding. Connecting mountain top removal for coal to global climate change may not get us to write Congress to stop that practice.

In spite of that, I believe everyone working on environmental issues should be aware of the whole picture, even while focusing on his/her own particular cause.

Global climate change has gotten the attention of the country and the world as no other environmental issue has.  I doubt the insurance companies have been so aware in their entire history! So, let's continue on all fronts and keep the dots connected.
