Did you know more than 12 million tons of furniture is thrown out every year, and almost all of it ends up in landfills? Among the biggest items are sofas; there are things you can do to make sure your own sofa lasts (almost) a lifetime. First, keep your sofa away from the sun's rays, which can fade fabrics (also known as "sun-bleaching"). Rotate cushions so they wear evenly -- this will prevent denting and help them maintain their shape. Spot-treat spills quickly, and vacuum often to keep dirt, dust and debris out of the fabric.

Washing your clothes in cold water does more than save energy and money on your utility bill: It also preserves your clothes. The fibers of your clothing last longer when they're washed in cold water; they actually deteriorate when washed in hot water. The only time you really need to wash in hot water is if you need to remove stubborn stains that are oil-based, or to disinfect items like hand towels and bedding. Otherwise, 9 out of 10 washes on average should be done in cold water.

If you're lucky enough to fly somewhere and have the option of a meal on the plane as part of your travel, you can take steps to reduce food waste. If you get an upgrade to a premium class and you plan on sleeping during the flight, go to the airline's website to opt for "no food" so no meal will be prepared for you. This will help reduce food waste, since none of the prepared food can be reused after the flight lands. And remember to bring your reusable water bottle with you when you travel to avoid plastic cups and other single-use plastics when drinks are served in-flight.
