can you suggest a good investigatory project with the theme,"environment friendly"...tc,thanks?

like having a product made of another product

Answer 1

Well if you are in school, you can investigate how "environmentally friendly" your school is. Do they recycle or reuse things they can? Do they throw out tons of paper?

If you're not in school, look at a local company or industry and see how they are or are not environmentally friendly.
