In addition to being an unhealthy oil that's high in saturated, artery-clogging fat, palm oil should be avoided in foods to help protect endangered orangutans. These intelligent animals, found in tropical rain forests in Sumatra and Borneo, are being eradicated as their homeland is cleared to make room for palm tree oil farms. As the rainforest land is cut, orangutans are displaced and killed, and baby orangutans are often left orphaned. To avoid palm oil, look for pure oils like sunflower, olive, corn or coconut oil. Avoid anything labeled "vegetable" oil -- there is a strong likelihood that a high percentage of that vegetable is actually palm.

Wild animals are attracted to any sources of food and will come back time and time again looking if they find it. While we can help wildlife by using tight-fitting garbage cans and not intentionally feeding them, there are items that may be inadvertently attracting them. In addition to easy-access bird feeders and unturned compost bins, well-used barbecue grills can be tempting, too. The smell of charred meat and vegetables can entice bears and other animals. To prevent your grill from being torn apart, give it a good scrubbing and wash. When it's dry, fill it with wadded-up newspaper to help absorb odors -- just remember to remove it before you start the grill!

Over 300 million scrap tires are generated every single year in the United States, according to the Environmental Protection Agency. When your tires need to be replaced, do it with a reputable dealer that will recycle your old ones. Many tires today are being shredded and used in roadways and also being made into other products. But to limit the number of tires you replace in the lifetime of your car, try these tips to prolong their life. First, look for new tires that have longer tread life; they may cost a little more, but in the long run, you save money. Also, be sure to rotate your tires every 4,000 miles to even out wear, and balance the tires with each rotation.
