I'm thinking whether in addition to the bike, we can help. There are also many different ways, such as reducing the use of plastic bags, inside the store, cafeteria and a change in fabric bags instead.
I think apart from cycling, we can help global warming. There are other ways, such as reducing the use of plastic bags in the store cafeteria on campus. And switch to cloth bags, paper bags instead.
I think we can save the earth than the bike, there are many many ways such as reduction in use of plastic bags. Within shops, canteen. In the University, and change to use cloth bags, paper bags instead.
