They're not deniers, they're not optimists, and they're not fatalists. Only the most stupid people are actually unaware of the dangers of global warming, which we see daily. What they are is freakin' lazy. They know what they need to do, but they are unwilling to change their habits or give up their conveniences. It's not easy trying to do the right thing, and few of us get it right 100 percent of the time. However, we accept the truth and are willing to go out of our way, not only for ourselves, but also for those on the planet who are suffering because of our selfishness. Remember what they say about lighting just one candle.
