what the waste equates to, especially in terms of methane production from rotting food gas emissions as well as the amount of resources that go into production.
And the emissions that go into carting it away on the rubbish truck. And don't go thinking "Oh, but the truck comes anyway" If it comes, and is only half as full, it has to do fewer trips. A lighter load means lower fuel consumption too.

Waste is bad, mmmmkay?
