Millions of people travel by airplane every day. Planes can release half a million pounds of carbon dioxide in a single trip.
Scientists are developing an eco-friendly alternative. Lipidcane is an engineered form of sugarcane that produces lipids. Lipids are a key ingredient in biofuel, which can also power planes.
Biofuel still releases carbon dioxide when it is burned but the lipidcane crops absorb carbon as they grow. So it is ultimately a greener fuel option. Scientists believe lipidcane could replace 65% of national jet fuel consumption which would leave behind cleaner skies.
