City dwellers who rarely use their car may want to think twice about keeping it. On average, the cost of gas, registration, insurance and payments (if the car isn't owned outright) can add up to around $10,000 a year. A car that isn't a daily necessity can be sold to save money; experts agree that when you do need a car, renting is the most economical and ecological way to go, since you only use it when you really, truly need it. Of course, you can always donate a car you own outright to charity and reap the tax deduction savings, too.

This holiday season, instead of choosing between a live or an artificial Christmas tree, consider renting one instead. Live balled trees can be rented from local landscaping stores, and they will often deliver the tree and take it back after the Christmas holiday. If your local store doesn't have such a program, why not propose it and see if they'll go for it? It's a win-win for them: They get revenue for a tree they can't plant now and they also get it back. If you prefer an artificial tree, local prop houses (typically used by set designers) will often rent trees to the public at a tiny fraction of the cost. The benefit? When the holiday season is over, you can return it and not deal with storing it.

Did you know over 1 billion plastic toothbrushes are used every year in the United States, and almost all of them end up in landfills? One way to help avoid this waste is to look for more environmentally friendly alternatives, like brushes with renewable bamboo in lieu of plastic for the handles, which are biodegradable and a much greener choice than conventional brushes. If you do have plastic brushes, consider using them around the house when they are too worn for your teeth. Save them for scrubbing hard-to-clean areas on tile grout and keyboards; you can even use them to give your jewelry and shoes a good cleaning.
