Have you seen An Inconvenient Truth? It was pretty clear Al Gore doesn't expect people to do anything so radical, and people who suggest that that's the only way to get results, will scare people away from doing anything at all. More practical, widely excepted solutions (buying hybrids or other more efficient vehicles, and offsetting your emissions), are going to have better results because people will actually do them. Don't make living green sound miserable. The same goes for businesses, instead of saying, "well what about the poor oil companies," think of all the new jobs that will be created, all the money there is to be made, in search of green solutions.
