Transport - Walk, bike, carpool, or bus to work every day, and save your car for special occasions.

Turn Off - It's as simple as using less electricity. Make sure anything that uses energy is cut off when you are not using it.

Trash - Pay attention to packaging, refill water bottles, reuse grocery bags, and see how long you can go without creating any trash. And if you do, make sure it is recyclable.

Trees - Plant a tree and name it after yourself.
