New study quantifies differences in biofuel crops, impact on environment
"While some biofuels may be an improvement over traditional fuels, we believe we should focus much more on the biofuels of the future that can be developed in small spaces, rather than extensively on crop lands," according to lead author Martha Groom. "We also must shun biofuels that are grown by clearing biologically-rich habitats, such as tropical rainforests, as has occurred with oil palm and some other biofuels," she adds. The study also recommends that a special look be taken at crops which sequester carbon as they grow.
We may add that another benefit to both algae and fast-growing trees is that nobody is growing them already for food.
