Take a Bike Ride
According to the U.S. Department of Energy, highway vehicles release about 1.5 billion metric tons of greenhouse gases into the atmosphere each year. Take a family bike ride to one of the day's destinations, and ask your children if they can think of any other environmentally-friendly modes of transportation. You can get the conversation started by mentioning skateboards, rollerblades, or even your own two feet!
Open Your Windows
According to the EPA, air pollutants in the home can be 2-5 times higher than outdoor air pollutants. Throw open your windows and let the fresh spring air in! While you're at it, encourage your kids to listen for nature sounds and write down what they hear.
Get Outside
Picking up trash in your neighborhood, going on a scavenger hunt, or planting some flowers are all great ways to enjoy the outdoors and celebrate Earth Day.
