I'll throw my $0.02 in and then gently back away from the conversation. I'm am a proponent of clean-air regulations and some of the other environmental initiatives different groups have undertaken. I agree that there is no reason people need to drive gas-guzzling SUVs or sports cars.
However my support for the left-wing environmentalists stops when it comes to agricultural issues. They are so backwards it really is laughable. For the most part, these are the same people that support "organic" food in the belief that it's healthier for humans (despite having no credible scientific backing) and it will save the environment. What these people don't realise is that "organic" farming is not sustainable. When so much of the world is under-nurioused/starving, we should be doing as much as humanly (or humanely) possible to increase food production in the world. However, supporting organic means of farming means reducing crop yields by at least 50%! Not to mention the disease problems that would run rampant. To make up for the drop in production from world-wide organic farming, we'd have to tear up every last inch of arable land in the world. That would destroy thousands of species of wildlife and vegetation, and would in fact destroy the world. Starvation would be worse than it is now because foodstuffs would become too expensive for all but the richest countries. It is just so ironic that the one thing that the environmentalist agendas push (organic farming) is the one thing that could ultimately lead the world into ruin.
And don't even get me started on the GMO/nonGMO debate....
