According to Oxford University's Wildlife Conservation Research Unit, there are tourist traps around the world that exploit wild animals in the hopes you'll visit and participate. If you want to avoid supporting animal cruelty, be on the lookout when you travel abroad, and avoid these exhibitions at all cost. They include riding with elephants, taking selfies with any animal, performing and swimming with dolphins, holding wild animals like sea turtles and dancing monkeys. If it doesn't feel natural or right, it probably isn't.

Storing leftovers in the refrigerator used to mean covering bowls with non-recyclable plastic cling wrap or using plastic storage containers that can stain and take on odors very easily. Silicone food storage lids are a good investment that can turn any bowl or container into an airtight storage container. The lids simply wrap around the top and create an instant seal. They're also freezer- and microwave-safe, they don't take on odor or stains, and they can be washed and used over and over. And while silicone itself is not recyclable, the lids don't leak any chemicals into the environment when thrown away.

You might wonder if frozen vegetables are more wasteful for the environment, since they have be kept frozen from the factory, in the store and at home in your own freezer. The answer is, it depends. Researchers say frozen food can have a lower carbon footprint in comparison to fresh food, since it leads to less food waste at home; most people completely use up frozen food when cooking. But if you don't waste any food when you buy fresh, then go that route. Because when you add the extra packaging, processing and, yes, the electricity to keep things frozen, fresh wins -- IF you use it all up.
