One of the more "enlightening" articles I found was on a website called "americablog" (yeah, right), with an article by a enviro-nutjob followed by comments by other enviro-nutjobs, all wailing about all the pipelines being built. One commenter in particular though was quite informative, as he's apparently a lib lawyer, and does know the pertinent laws, regulations, cases, etc., in and out.

Never mind that pipelines are the safest, lowest impact way to move oil or gas. Of course the biggest argument with this group opposing pipelines is that of global warming and and that we'll all cook. One commenter near the end despairs at the inevitability of the tar sands resources being used (assuming all the Canadians don't go totally insane), which is reason for me to brighten up!
Don't get me wrong, I enjoy a day fishing or hiking at some wonderful spot as much as any of the posters at that site. But I was SO tempted to register and ask a simple question: If human activities have such a big effect, what happens if you people get everything you want? Hint: Study the climate records for the last few million years.
