Algae are aquatic plants that can be a single cell, or a 20-foot long seaweed. Algae extracts are ingredients in an enormous number of products we use: foods, pharmaceuticals, biofuels, even surfboards. We'll talk about what algae are, visit research laboratories where new algae discoveries are made, see the huge desert farm that grow algae, and head to Mexico to see how algae surfboards are made.
