Question

What are some factors that contribute more recycling and less littering?

Answer 1

There are recycling stations that will exchange cans and bottles for money.  They weigh all the aluminum cans or beer bottles (there is a different exchange rate for green and clear bottles) and based on how much you brought, they will give you a check that you can go and get cash for at a neighboring store.  

  This not only makes people  more likely to recycle and not throw away their bottles and cans, but probably makes some refrain from throwing them on the side of the road.
