Light and dark of new energy development

The biodiesel fuel and the bioethanol get into the news as energy that takes the place of oil. However, the problem is caused, too. Brazil's production of sugarcane is active. Sugarcane is used as the bioethanol. The cane field is extending to Amazon now. Tropical forests might be destroyed. The government seems to think about measures against it. The new energy development is wonderful, but I want it to stop destroying the forest.
