The simple solutions to environmental degradation are less consumption or fewer people.
The past twenty years have definitely taught us that less consumption is out.
I wonder how long it will be before we see the first examples of bio-terrorism based upon environmental concerns (whether individual, group or sponsored by a state).
History has taught us that despite the monstrous, unethical and vile nature of murderous acts such as genocide and eugenics, a madman's reasoning has often been used to justify these same acts in terms of some "higher purpose".
I have little doubt that there are madmen in our society today.
On a positive note, I'm very encouraged by Barack Obama's promise of $150 billion for clean energy research. I'm a little less impressed that this is over ten years. Still, it's a step in the right direction.
