Light-emitting diode (LED) lightbulbs are all the rage when it comes to lighting. But shopping for LED bulbs can lead to unexpected surprises when you turn on the bulb for the first time; the light emitted can feel cold, clinical and not warm at all. When shopping for LED bulbs, the key words to search for on the packaging are "warm white" or "soft white." But more importantly, look for kelvin ratings -- a metric to measure color temperature. LED bulbs that are 3,000 kelvins or fewer cast a yellow light; any higher, and it'll likely be a cooler, bright white light.

What should you do with all the packaging that comes with online orders? Both plastic bubble wrap and plastic air pillows can easily be recycled. Find a plastic shopping bag recycling bin (most supermarkets have them), and deposit them there. Bubble wrap and air pillows are made from the same kind of plastic as the shopping bags and will be recycled into new plastic products. Just do one thing before putting them in: Pop the bubbles so they don't take up all the room in the bin.

Little bottles of nail polish can dry out or go bad, but think twice before you toss the jars into the trash. Almost all nail polishes (with the exception of a few eco-friendly brands) have volatile chemicals in them, like toluene and dibutyl phthalate. These chemicals aren't just flammable -- they are considered household hazardous waste. Because of this, they should be disposed of with other household hazardous waste when you have special collection days in your community. In some cities, it's outright illegal to throw old nail polish in the trash.
