Carbon dioxide (CO2) gives soda its fizz and champagne its sparkle. But increased levels of CO2 in the atmosphere due to human activities can cause the Earth to warm and oceans to acidify at alarming rates. Scientists have long sought to find clean, green alternatives to fossil fuels like gasoline, which exacerbate the CO2 problem, and biofuels—fuels derived from biological resources such as plants or plant biomass—are considered a renewable solution.
A team of scientists is working to create sustainable algae-based biofuels that could reduce CO2 and other harmful emissions in the atmosphere.Image credit: Kathy F. Atkinson
