Algae have sustained life on this planet since they were first modified the atmosphere with photosynthetic by-products over two and a half billion years ago. From the microscopic to giant seaweeds, over 30,000 different forms exist today. In this program researchers discover how algae can transform, from life supporting to life threatening. Learn how we've depended on algae in the past and see the new ways we are putting them to use in cancer research, sewage and wastewater treatment, agriculture and household products.
