Environmentalists insist that deforestation is a major factor in global warming because it is contributing as much as 20 percent of the “greenhouse effect” – the process whereby the atmosphere is less able to cool itself, thanks to excessive amounts of gases like carbon dioxide (CO2). But CO2’s villainy puts environmentalists in an unexpected corner. To contain global warming, government pressures private businesses to reduce their carbon dioxide emissions. But that pressure also encourages private companies like the utilities that generate electricity to find substitutes for the coal they currently depend on. So, guess what many utilities here and in Europe are starting to burn?

Wood.
