Tired of getting preapproved credit card offers in the mail that just end up in the trash? It's easy to unsubscribe from these offers with just the click of a mouse. Under the Fair Credit Reporting Act, credit reporting companies are allowed to use your name on lists to creditors to make you offers for preapproved cards, but you can opt out from being on the list -- which eliminates the junk mail offers -- by visiting optoutprescreen.com. You can choose to opt out for five years or forever, and you can even opt back in if you ever want to be back on the list.

If you've boiled or flash-cooked a large pot of vegetables, don't toss the leftover water down the drain. Instead, let the water cool and give your houseplants or garden a nutritionally packed treat to help them thrive. The residual vitamins that come from the vegetables are incredibly beneficial for plants. Just make sure the water is completely cooled and free of any salt, which is dehydrating and damaging to plants. If there are bits of cooked vegetables in the water, strain them out before using the water for your plants.

Here's an easy way to reuse plastic bubble wrap to help save energy at home: Use it in your freezer. Since bubble wrap has pockets of air that help insulate, wrapping items that need to stay frozen helps them stay ice-cold easier, especially if you open the freezer door regularly. Consider wrapping containers of ice cream and frozen meats in bubble wrap, and even laying sheets of it on the freezer shelves. Every time you open the freezer door, the bubble wrap helps keep the food frozen longer, so your freezer doesn't have to work as hard to keep temperatures low. You can also use it in the refrigerator to line shelves that hold beverages to help them keep their chill.
