One of the easiest ways to help ecological conservation and wildlife conservation is to cut down on the amount of plastic bottles we use every day. Single-use plastic bottles are bad because a majority of them do not get recycled, and end up in the ocean instead.

Worldwide, almost 1 million plastic bottles are bought every minute. That means in 2 days, there are enough plastic bottles to rebuild the Eiffel Tower. And plastic bottles aren’t just bad for the planet, they're also bad for your body and your budget. A recent study found microplastics in 93% of water from single-use bottles, which means you could be chugging something even scarier than frat party punch. (Ugh.) Then there’s the cost of single-serve water, about $2—$4 down the actual drain.

The easy way to keep yourself and the earth cleaner: Keep a reusable bottle in your work bag, your gym bag, your car, and your carry-on tote. You can potentially save over $500 a year and save the 800+ species (including humans, BTW) harmed by plastic pollution. Environmental sustainability the easy way, right?
