Of course they should but placing restrictions on them that put them out of business would absolutely destroy our economy. Yes, responsibility to the environment is important but it means jack shit if it leads to another depression.
Global warming isn't much of an issue when you're burning stacks of benjamins to stay warm and wondering if your dog has enough meat to feed your family for the week.
The key it to have reasonable moves toward cleaner technology. Technological innovations come from industry, not government. We didn't get to the moon by giving NASA billions of dollars and having them build everything in-house. They relied on the private sector to develop, engineer and build just about every aspect of the program.
Allow capitalism to take its course with reasonable direction by the people and we'll enjoy cleaner technologies a hell of a lot sooner than we will by tightening the noose on oil companies and forcing third world nations to adopt overly expensive technologies.
I agree. However part of that lack of future sight includes ignoring the economic effects of placing a stranglehold on the very companies that are most likely and most capable of creating these new, cleaner technologies. Shell, BP and all the others are quite literally the best hope for alleviating both our reliance on foreign oil and our polluting ways.
Oh, let's not forget that the biggest polluter in the world is the US federal government itself.
If they don't have to follow their own rules, what's the fucking point?
