Earths climate has only gone up one degree or something like that. I just don't think there is any globol warming. And to correct you on the dam situation with the enviorment. dam companies now do something to make salmon or any fish get through the dam and back up stream. They transport the salmon through special compartments in the dam and that lets the fish through.
And even lumber companies nowadays are renewing the enviorment. Every time they cut down a forest they replant new trees to renew the landscape. A lot of companies have come a long way since their beginnings. I mean you would think that since we cut forest down to make paper and other things that we would have no more forest. Well half of Americas forest are comming back. So that tells you that we must be learning from our mistakes in the past.
