Happy Earth Day!

In honor of Earth Day, here are 3 simple things you can do to help the planet:

• Eat less meat. Raising livestock is one of the most significant contributors to a long list of environmental problems from climate change to deforestation to water pollution. No one is suggesting you go vegan, but anything you can do to cut back on meat will make a big difference. Start by trimming down your portion size to about three ounces (the size of a deck of playing cards), suggests Aaron Huertas at The Union of Concerned Scientists.
• Take good care of your car. Tuning up your engine, replacing your air filters and motor oil regularly, and keeping your tires properly inflated will improve your car's fuel economy by 8% to 20%, according to Jenny Powers at the Natural Resources Defense Council.
• Make changes in how you do your laundry. Wash your clothes in cold water. Up to 90 percent of the energy used for washing clothing goes to heating water, according to the Department of Energy. Rack up even more savings by air-drying some of your clothing.
