"What we need is a less exploitative model of agriculture. Vast areas of the developing world are being turned over to cattle grazing, or soy for cattle or biofuels so the rich world can eat more meat and drive around in ecological cars when the priority should be ensuring there is enough affordable food for everyone.

Taking up valuable land and growing edible crops for biofuels poses a dilemma: Is it ethical to produce inefficient renewable energies at the expense of an already malnourished population? David Pimentel and his colleagues from Cornell University in New York highlight the problems linked to converting a variety of crops into biofuels. Not only are these renewable energies inefficient, they are also economically and environmentally costly and nowhere near as productive as projected. [...more]
Biofuels, nuclear energy and coal are the worst choices for energy alternatives to petroleum products and wind, solar, geothermal, tides and waves are the best, according to results from the first quantitative, scientific evaluation of the proposed, major, energy-related solutions that assesses not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability.

Food prices have soared over the past year. One might think that this would provide a welcome boost to the incomes of the world’s poorest people, most of whom are farmers and farm workers. But it doesn’t work that way, as Raj Patel explains [...more]
It was one of the dumbest "green" ideas ever proposed: Convert millions of acres of cropland into fields for growing ethanol from corn, then burn fossil fuels to harvest the ethanol, expending more energy to extract the fuel than you get from the fuel itself! Meanwhile, sit back and proclaim you've achieved a monumental green victory (President Bush, anyone?) all while unleashing a dangerous spike in global food prices that's causing a ripple effect of food shortages and rationing around the world.

Findings have major implications for climate change policy Turning native ecosystems into "farms" for biofuel crops causes major carbon emissions that worsen the global warming that biofuels are meant to mitigate, according to a new study by the University of Minnesota and the Nature Conservancy.

Heightened concern about oil dependence is generating growing support for alternative transportation fuels, but some would emit significantly more global warming pollution than gasoline or diesel, according to a report issued by the Union of Concerned Scientists (UCS). [...more]
