Got a dead houseplant? There's no need to toss it into the trash, where it won't have a chance to biodegrade in the landfill. In fact, even though it's dead, it can help create healthy soil in your yard or garden. Remove the dead plant and shake off the excess potting soil. Use a lawnmower to pulverize it into smaller pieces. The organic matter can be added to a compost bin or sprinkled on the yard, where it will naturally decompose in no time.

Here's a reason to use biodegradable, plant-based soaps in your bathing routine: Plants love it! The next time you take a bubble bath and use eco-friendly soap, save some of the used water for your outdoor plants. The natural phosphates that make the bubbles are natural fertilizers for plants. Fill a watering can or bucket with bathwater and water the roots of the plants.

The next time you get in your car, open all the windows. When your car is parked in the sun with all the windows closed, it creates a mini greenhouse that raises the interior temperature of your car considerably. On hot days, you'll want to turn on the air conditioning right away, but letting the hot air escape through the windows makes the air conditioner more efficient when you turn it on a few minutes later. There are some studies that suggest that the heated plastics inside the car can release various toxins on particularly hot days, so this also helps ventilate the air, too.
