Several new studies show the biofuel boom is doing exactly the opposite of what its proponents intended: it's dramatically accelerating global warming, imperiling the planet in the name of saving it.
it does makes sense...
look at this picture
The tiny rain forest is surrounded by (whooping! 200,000) hectares of soybean fields in the Mato Grosso state, Brazil.
An explosion in demand for farm-grown fuels has raised global crop prices to record highs.
Advocates are always careful to point out that biofuels are only part of the solution to global warming, that the world also needs more energy-efficient lightbulbs and homes and factories and lifestyles. And the world does need all those things. But the world is still going to be fighting an uphill battle until it realizes that right now, biofuels aren't part of the solution at all. They're part of the problem.
Anyway, the full topic can be read here -

in summary - its saying biofuel is doing exactly the opposite of what it was intended for.
What cha think? Our government are also encourahing biofuels - more deforrestation here. A lot of countries are also doing the same.
