I have to side with the skeptics here. There always seems to be a collective anxiety over issues that concern our mortality and future. The media, and poor unsubstantiated science only egg on the frenzy.
125gjoe posted an interesting link about our environmental hysteria a few months ago. I'll see if I can find it to post here. Hopefully Joe will see this and post it first.
While I do appreciate our environment, I don't find it necessary to go out of my way practicing "green living."
I won't litter. I'll use a cheaper, more efficient fuel source if available. I'll toss my can in the recycling bin if one is available, but at the same time, I'll happily drill for oil in my backyard in spite of the pretty landscape around me.
