ALGAE AND SUSTAINABILITY

Abstract

Algae (phytoplankton and seaweeds) and their plant descendants shaped the Earth’s environment over millions of years to make human existence possible. Food ultimately provided by phytoplankton supports nearly all aquatic animal life, and algae influence key phenomena underpinning the sustainability of life. The natural contributions of algae to a sustainable existence can be augmented through human effort to counter some of the adverse impacts of human activity on climate and the biosphere. As discussed in this article, algae have the potential to sustainable supply food, feed, fuels, other renewable chemicals and materials. They can be used to renewably clean up the environment.
