How I learned to start worrying and hate the tar sands pipeline
Bill McKibben sure is making a big deal over a commodity piece of oil infrastructure. He and more than 200 climate activists think it’s worth getting arrested to stop TransCanada from building the Keystone XL Pipeline. Sure, tar sands are uber-dirty. But with such a low energy return, won’t high costs just make them go away on their own? That’s what I always assumed. But now I’m starting to think this thing could be bad. Really bad.
