Most people are familiar with the “Three R’s” — reduce, reuse, and recycle. But many of us don’t know the everyday steps we can take to make those R’s impactful — and we don’t realize how big that impact can be when our individual efforts add up.

It’s tough to know how much your minor changes can affect the planet on a larger scale. It can feel like your contribution is small and insignificant, when in fact it’s not. Throughout Earth Week, NBCUniversal will share both habits that anyone can do to make a difference, as well as the impact those habits have on the planet.

This story is part of NBCUniversal’s 10th Annual Earth Week where we’re inviting our viewers and readers to “Green Up” by sharing steps you can take to help the planet. Follow Facebook, Twitter and Instagram for more. #GreenUp
