Why biofuels will lead to increased greenhouse gas emissions. It takes too much land to plant the proper pla?

"The government’s policy of promoting biofuels for transport will come under harsh attack this week from one of its senior science advisers. Roland Clift will tell a seminar of the Royal Academy of Engineering that the plan to promote bioethanol and biodiesel produced from plants is a 'scam.'" By the way, when you hear biofuel, think plants. That's what it means. "He will tell the seminar that promoting the use of biofuels is likely to increase greenhouse gas emissions. Clift’s comments will amount to a direct challenge to Miliband, who has published a strategy promoting biofuels. It coincides with a surge of anger among environmentalists over the weak pledges on climate change that emerged from last week’s G8 summit." And boy, you know, you can talk about Bush all you want, but he stuck it to Putin and stuck it to the G8 on the Kyoto protocol. It's effectively dead. He effectively just wiped it out; made them wipe it out. Now, here's why biofuels will lead to increased greenhouse gas emissions. It takes too much land to plant the proper plants for biofuels. In order to get the land you have to burn down forests. And when you burn forests, the carbon dioxide that these forests normally scrub from the air will remain. This, according to environmental lore, will contribute to global warming. That's all hocus-pocus as well. I mean, CO2, we exhale it. It's not a pollutant.
