Reduce the amount and toxicity of trash you throw away and reuse containers and products. Recycle as much as possible and buy products with recycled content. Practice composting by using microorganisms (mainly bacteria and fungi) to decompose organic waste, such as food scraps and yard trimmings. Buy more used clothes (at second-hand and thrift stores) rather than new. The processes used to make new clothes greatly impact the environment and contribute to climate change. Recycling one aluminum can saves enough energy to run a 100-watt bulb for 20 hours, a computer for 3 hours, or a TV for 2 hours. Buy products with less packaging. Bring a reusable bag to the grocery store to cut down on the use of plastic or paper bags. Make use of free services to get rid of your unwanted household items. For example, donating to Freecycle, consignment shops, thrift stores, churches and at special drop-off events.
Fast facts

The United States has 5 percent of the world's population and 30 percent of the waste. The average person consumes twice as much as 50 years ago. The average American creates 4.5 pounds of garbage every day. Recycling 1 ton of paper saves 17 trees, two barrels of oil (enough to run the average car for 1,260 miles), 4,100 kilowatts of energy (enough power for the average home for 6 months), 3.2 cubic yards of landfill space, and 60 pounds of air pollution.
