Easy Ways to Take Back the Planet
Reader Tip: Tread Lightly
Start with yourself, and lead by your life's example. If you are concerned with the affects of pollution, over-consumption, encroachment, and extinction, you must start by "walking lightly" on the earth and being aware of how your choices impact the world.
Make transportation choices that consume less energy (e.g. walk, ride, public transit, carpool). Stop being driven to compete with your neighbors for status goods. Learn to distinguish what you need from what you desire, and then make intelligent choices based upon how much utility you gain.
Then you can take some of the money you've saved and use it to support groups that are making a difference. Volunteer some of your time as well as your money. And then stop, and notice how meaningful your life.
