Heard Jim and Lisa on the morning show talking about whether or not you celebrate Earth Day. The verdict is still out on this one, some do, some don't, from the responses gathered on facebook.

Here’s how to set some positive waves in motion:

• Recycle bottles, cans, plastic, and newspapers. This helps conserve our natural resources for future generations. It also reduces the need for landfills and supports the U.S. workers who make recycled goods.

• Go green for lawn and garden care. If you use pesticides, spot-treat problem areas instead of putting chemicals on the whole yard.

• Save the world with your wallet. Cut down on waste by buying reusable products instead of disposable ones; for example, cloth napkins instead of paper. Purchase recycled or recyclable items when available

Check out these videos that NASA put together for Earth Day that I thought was pretty cool showing off our big blue planet from space.

Here's a special greeting from the International Space Station.

Finally, some comedy relief about Earth Day.
