We have all heard that reducing our meat intake can have a profound impact on greenhouse gas emissions. In fact, according to Conservation International, our global food system contributes nearly 1/4 of those emissions. While a vegetarian diet is the greenest, it's not the only choice. To reduce global warming, keep these numbers in mind: A 6-oz serving of beef equates to 330 grams of CO2. Compare that to chicken (50 grams), fish (40 grams) and vegetables, which come in at just 14 grams. Switching from beef to chicken or fish is one easy way to help reduce emissions.

With the holiday season around the corner, many of us will be out looking for the perfect gift or shopping online to save time. The good news is that online shopping does have a smaller carbon footprint than driving to a store. But shipping can negate those environmental savings. First, avoid the fastest shipping option; overnight shipping results in much higher greenhouse gas emissions than ground shipping. And don't buy things with an "if I don't like it, I'll just return it" mindset. Buying carefully and responsibly, making sure that what you order is what you really need, can have a big impact.

According to the Humane Society of the United States, a large number of pets have died as a result of toxins from flea treatments, so finding safe and natural ways to prevent and kill fleas is important for the furry members of your family. Prevention and common sense can go a long way. Vacuuming carpets, rugs and furniture where your pet lives along with washing his bedding in hot water regularly can capture and kill fleas. And real lavender essential oil can also help for dogs: Add some to a natural flea soap and let the mixture sit on the coat for 10 minutes during bath time. Rinse and repeat.
