ay attention to how you use water. The little things can make a big difference. Every time you turn off the water while you're brushing your teeth, you're doing something good. Got a leaky toilet? You might be wasting 200 gallons of water a day [Source: EPA]. Try drinking tap water instead of bottled water, so you aren't wasting all that packaging as well. Wash your clothes in cold water when you can.
2. Leave your car at home. If you can stay off the road just two days a week, you'll reduce greenhouse gas emissions by an average of 1,590 pounds per year [Source: EPA]. Combine your errands -- hit the post office, grocery store and shoe repair place in one trip. It will save you gas and time.
3. Walk or ride your bike to work, school and anywhere you can. You can reduce greenhouse gases while burning some calories and improving your health. If you can't walk or bike, use mass transit or carpool. Every car not on the road makes a difference.
