Has global warming wilted your sense of humor? Is your patience worn thinner than the ozone layer? If you're overwhelmed by the mess we call our environment, then stretch out under a tree (remember them?) with these cartoons and see if a good laugh won't sweep the cobwebs (and asbestos) from your troubled mind and help renew your commitment to making our earth a better place. Aside from being just plain hilarious, Sidney Harris is a whiz at defusing panic-button issues and debunking both the politically conservative and politically correct. So, let the bottom-liners, P. R. flaks, and slash-and-burn developers square off against the doomsayers, granolaheads, and tree-huggers. Sidney Harris will help them stay focused on the issues while he gives the rest of us, who ask only for an occasional breath of fresh air and glass of clean water, something to laugh about - and hope for.
