I'm just not sure how much effect humans have in the eqution. The finger lake I sail on was formed by a glacier, long before man could have had an effect on melting the glacier away. I do think we should respect the environment, not be wasteful, and recycle as much as practicle.
Personally, I've got things covered. If it ends up being global cooling, than I have more time in my iceboat. If it's global warming, then thats a longer wet water sailing
season. If the ocean levels rise due to the icepacks melting, then hopefully I'm looking at my home in central NY becoming beachfront property!
