Compost. This is an easy method to save space in the landfills, as well as return valuable nutrients to your soil.
Reuse items. Glass jars and empty shoe boxes can be reused as storage containers.
Resell or donate used items instead of throwing them away.
Avoid using disposable items (e.g. paper plates, plastic utensils, etc…).
Drink tap water or use a water filter instead of buying bottled water.
Cook at home instead of eating pre-packaged foods.
Buy things in bulk; this saves on packaging.
Borrow items that are rarely used (e.g. ladders, rakes, etc…)
Reduce the size of your items before you recycle or throw them away. Some items can be cut into smaller pieces, or taken apart, so they take up less space in the landfills.
