Plant a tree; pick up litter around your neighborhood, local park or nearest waterway; take the time to learn more about current environmental issues in your state and it impacts the world, or contribute to an Earth Day event near you by volunteering your time or attending with family and friends.
Leave your car at home for a day (or a week or a month) and try walking or biking. If work is too far away to walk, take public transit or carpool. One city bus eliminates the emissions of 40 cars.
Turn off the lights, the computer and the television when they are not in use. Using only highly efficient and money-saving appliances can reduce the electricity consumption of an average household to one-10th of the national average.
Try eating meat-free at least one day a week. A meat-based diet requires seven times more land than a plant-based diet. Livestock production is responsible for more climate change gasses than all the motor vehicles in the world.
Choose foods produced organically, locally and in season. Support your regional farmers and farming industry: buying locally and in season is better for the environment than buying foods that have been shipped hundreds of kilometers to your local market.
Put a composter in your backyard or use your green bin to reduce household waste. Composting organics has two key benefits: it reduces the amount of waste going to landfills and when added to your garden, helps nourish soil and plants.
Turn off your car's engine if stopped for more than 10 seconds. If every driver of a light-duty vehicle avoided idling by five minutes a day, collectively, we would save 1.8 million liters of fuel per day, almost 4500 tons of GHG emissions.
Set your thermostat above room temperature in the summer and below room temperature in the winter. For each degree you adjust, you can save 5% on your utility bill and 1% on your energy use.
Replace incandescent light bulbs with compact fluorescent bulbs (CFLs). A CFL uses only 25% as much energy as an incandescent bulb and lasts 10 times longer.
The simple act of recycling has more impact on the environment than you think. The amount of wood and paper North Americans throw away each year is enough to heat five million homes for 200 years.
