Could you imagine a world where no one used gasoline? I have recently been interested in the applications of algae in our society. Did you know, you can use algae to treat sewage, increase food supplies, and even generate energy? Wow what a package. Scientists are implementing algae ponds in countries like India and Africa to clean waste and feed starving individuals.
I think this should be pushed to be implemented into more countries. It is just what we need.
