From now on, every time parents in UK fill up at a petrol pump, they’ll be putting fuel made from plants into the car. Under new rules, all petrol and diesel must contain a tiny bit of biofuel, which is made from crops like corn and wheat. The UK government wants more people to cut pollution levels. But some scientists and eco-groups say biofuels could do more harm to the environment than good. Biofuels are made from crops like corn. Campaigners say people have been forced from their land and rainforests destroyed, to make space for crops to grow. They say it takes a lot of energy to make the crops into fuel, and warn using biofuels will lead to rise in food prices. Minister for Transport Jim Fitzpatrick, said using biofuels would help cut release of carbon dioxide.
