"If we all wait for the great, glorious revolution there won't be anything left," author and environmental activist Derrick Jensen told me when I interviewed him in a phone call to his home in California. "If all we do is reform work, this culture will grind away. This work is necessary, but not sufficient. We need to use whatever means are necessary to stop this culture from killing the planet. We need to target and take down the industrial infrastructure that is systematically dismembering the planet. Industrial civilization is functionally incompatible with life on the planet, and is murdering the planet. We need to do whatever is necessary to stop this."

The oil and natural gas industry, the coal industry, arms and weapons manufacturers, industrial farms, deforestation industries, the automotive industry and chemical plants will not willingly accept their own extinction. They are indifferent to the looming human catastrophe. We will not significantly reduce carbon emissions by drying our laundry in the backyard and naively trusting the power elite. The corporations will continue to cannibalize the planet for the sake of money. They must be halted by organized and militant forms of resistance. The crisis of global heating is a social problem. It requires a social response.

The United States, after rejecting the Kyoto Protocol, went on to increase its carbon emissions by 20 percent from 1990 levels. The European Union countries during the same period reduced their emissions by 2 percent. But the recent climate negotiations in Bangkok, designed to lead to a deal in Copenhagen in December, have scuttled even the tepid response of Kyoto. Kyoto is dead. The EU, like the United States, will no longer abide by binding targets for emission reductions. Countries will unilaterally decide how much to cut. They will submit their plans to international monitoring. And while Kyoto put the burden of responsibility on the industrialized nations that created the climate crisis, the new plan treats all countries the same. It is a huge step backward.

"All of the so-called solutions to global warming take industrial capitalism as a given," said Jensen, who wrote "Endgame: The Problem of Civilization" and "The Culture of Make Believe." "The natural world is supposed to conform to industrial capitalism. This is insane. It is out of touch with physical reality. What's real is real. Any social system it does not matter if we are talking about industrial capitalism or an indigenous Tolowa people-their way of life is dependent upon a real, physical world. Without a real, physical world you don't have anything. When you separate yourself from the real world you start to hallucinate. You believe the machines are more real than real life. How many machines are within 10 feet of you and how many wild animals are within a hundred yards? How many machines do you have a daily relationship with? We have forgotten what is real."

The latest studies show polar ice caps are melting at a record rate and that within a decade the Arctic will be an open sea during summers. This does not give us much time. White ice and snow reflect 80 percent of sunlight back to space, while dark water reflects only 20 percent, absorbing a much larger heat load. Scientists warn that the loss of the ice will dramatically change winds and sea currents around the world. And the rapidly melting permafrost is unleashing methane chimneys from the ocean floor along the Russian coastline. Methane is a greenhouse gas 25 times more toxic than carbon dioxide, and some scientists have speculated that the release of huge quantities of methane into the atmosphere could asphyxiate the human species. The rising sea levels, which will swallow countries such as Bangladesh and the Marshall Islands and turn cities like New Orleans into a new Atlantis, will combine with severe droughts, horrific storms and flooding to eventually dislocate over a billion people. The effects will be suffering, disease and death on a scale unseen in human history.

We can save groves of trees, protect endangered species and clean up rivers, all of which is good, but to leave the corporations unchallenged would mean our efforts would be wasted. These personal adjustments and environmental crusades can too easily become a badge of moral purity, an excuse for inaction. They can absolve us from the harder task of confronting the power of corporations.

The damage to the environment by human households is minuscule next to the damage done by corporations. Municipalities and individuals use 10 percent of the nation's water while the other 90 percent is consumed by agriculture and industry. Individual consumption of energy accounts for about a quarter of all energy consumption; the other 75 percent is consumed by corporations. Municipal waste accounts for only 3 percent of total waste production in the United States. We can, and should, live more simply, but it will not be enough if we do not radically transform the economic structure of the industrial world.
