Oxford Biofuels- Operating since the 11th century, the University of Oxford is the oldest university in the English-speaking world.

It's part of a trial of alternative fuels for the University's vehicles. Red Algae- Vizhinjam is an idyllic fishing village on the western coast of India. For centuries the families in this village have derived their livelihood from fishing. But climate change and overfishing have affected stocks and families now struggle to make ends meet. There is hope however, and it comes in the form of a red algae or kelp, a type of seaweed. Thai Fish Leather- A few years ago, Thai fish skins were either tossed away or sold as cheap fried food. Now, they're used around the world as a stylish fashion material. The skin is from the tropical Tilapia fish, commonly farmed and sold in Thailand. At this seafood factory south of Bangkok, 30,000 pieces of Tilapia fish are cleaned, sliced and skinned every day.
