With more than 700 million users, Instagram is one of the most popular social networking sites ranking number three behind YouTube and Facebook. With Instagram playing such a significant role in the lives of many, particularly Millennials and Generation Z, it has all of the potential and reach to inspire today's youth to be more eco-conscious.

From organic eating to national parks and sustainable living, there are a myriad of eco-friendly Instagram accounts out there to follow. But how do you find them? One of the easiest ways is to search for hashtags using Instagram's search field. For instance, when we searched Instagram for the hashtag #ecofriendly, our search resulted in more than 1.8 million posts which included that hashtag. Other popular tags include #eco which generated close to 1.9 million posts, #ecofriendlyfashion with more than 80,000 posts, and #ecofriendlyproducts with almost 47,000 posts.

In doing similar searches, we discovered five eco-friendly Instagram accounts that we highly recommend following if you don't already.

EMMA WATSON

Best known for her role as Hermoine in Harry Potter, Emma Watson is also the UN WOMEN Global Goodwill Ambassador and a leader in eco-fashion. She has a personal Instagram account @EmmaWatson, but if you're interested in learning more about sustainable fashion, head over to @the_press_tour where you can follow Watson and her eco-friendly fashion choices as she tours the world to promote her latest films.

NATIONAL GEOGRAPHIC

National Geographic has been educating and inspiring people to care about the planet since 1888. Follow @natgeo and see the world through the lenses of some of the world's best photographers. If this ever-growing photo collection of rescue animals and melting glaciers doesn't inspire you to take action, we don't know what will.

NATURAL RESOURCES DEFENSE COUNCIL (NRDC)

Ready to take action but not sure where to begin? @nrdc_org is a great place to start! This not-for-profit organization is on a mission to "safeguard the earth – its people, its plants, and animals – and the natural systems on which all life depends." Not only will you gain insight into a broad range of environmental issues but you'll also have the opportunity to let your voice be heard and make decisions that can directly impact communities around the globe.

MindBodyGreen

Let @mindbodygreen be your go-to guide for inspirational quotes and advice for revitalizing the way you live, eat, and move. How can we be expected to take care of the planet if we can't take care of ourselves first? MindBodyGreen will teach you all you need to know about green beauty, wellness, healing elixirs, and how to become one with the earth.

OCEANA

Like @oceana, we're also about celebrating the ocean and protecting marine life. Oceana does a superb job at reminding us about the things that pose the greatest threats to our oceans such as offshore drilling, pollution, and destructive fishing – and then counteracts those cons by educating followers with positive images of turtles, sharks, and clean energy. To date, the foundation has protected over 1.2 million square miles of ocean and countless sea life.
