Big Oil will stop at nothing to pump every last drop of oil out of the ground, from paying scientists to say that oil spills, fracking and other routine matters of oil development projects aren’t harmful to the environment or human health, to deliberately poisoning the debate about how best to rein in climate change and bribing politicians to weaken environmental standards and other regulatory hurdles.

Los Angeles may be one of the most populous urban centers on the planet, but there’s black gold in them thar hills, and the oil industry is going to get it, one way or another. Even if it has to drill under your property from several miles away.
