Keystone XL is part of the final phase of extreme exploitation by the corporate state. The corporations intend to squeeze the last vestiges of profit from an ecosystem careening toward collapse. Most of the oil that can be reached through drilling from traditional rigs is depleted. The fossil fuel industry has, in response, developed new technologies to go after dirtier, less efficient forms of energy. These technologies bring with them a dramatically heightened cost to ecosystems. They accelerate the warming of the planet. And they contaminate vital water sources. Deep-water Arctic drilling, tar sand extraction, hydraulic fracturing (or hydro-fracking) and drilling horizontally, given the cost of extraction and effects on the environment, are a form of ecological suicide.
Appealing to the corporate state, or trusting the leaders of either party to halt the assault after the election, is futile. We must immediately obstruct this pipeline or accept our surrender to forces that, in the name of profit, intend to cash in on the death throes of the planet.
