getting fuel from plants seems like a great proposition originally. It reduces dependence on foreign oil, and it doesn't produce the greenhouse gases that cause global warming â€" at least that's what advocates claim. But biofuels are not without their critics.
Some recent research suggests bio fuels could have a greater environmental impact â€" biodiversity loss, destruction of farmland, and the energy necessary to produce them, for example than burning fossil fuels, reports The Guardian, a British daily.
