Question: how could you make all plastics biodegradable?

This is a really tough question, and if I had the answer I think I’d be very rich!

I think that the best way to try is to take plastics that are made from nature (you can find them in wood, from plants and even from the shells of crabs) and to try to change them to make them better. This could mean using new chemicals to make them less likely to break or better at storing drinks in without being dissolved by the drinks.
