Nature provides us with the a variety of natural resources to spur innovation, and all right at our doorstep: sugar cane remnants are saved from the trash heap and turned into eco-friendly plastic, bamboo becomes an ideal building material because it re-grows faster than any tree, and coconut is a multi-purpose star, used for everything from medicine to green fuel. All it takes is a little imagination and inspiration. Across the world, people are protecting the environment by using resources in a smart and eco-friendly way.
