David Attenborough just joined Instagram. Here are 4 other climate warriors to follow too.

British naturalist, Sir David Attenborough joined Instagram this week, quickly breaking Jennifer Aniston's record for the fastest account to reach one million followers, and we couldn't think of a more worthy contender.

At 94 years old, Attenborough explained his decision to join the platform was due to the urgent climate crisis.

"I am making this move and exploring this new way of communication to me because, as we all know, the world is in trouble," he said in a IGTV piece-to-camera.

"Continents are on fire. Glaciers are melting. Coral reefs are dying … The list goes on and on. Saving our planet is now a communications challenge.

"Over the next few weeks, I'll be recording messages to explain what the problems are and how we can deal with them."

The Instagram was launched in the lead-up to Attenborough's newest documentary A Life On Our Planet, which will be dropping on Netflix on October 4.

Watch David Attenborough's warning about the climate, earlier this year. Post continues below.

So, while you're out having a stalk of David Attenborough's environmentalist content, we thought we would compile a few other eco-warriors that are worthy of checking out and adding to your feed, too.

Leah Thomas

Leah Thomas is the founder of Intersectional Environmentalist, an organisation that combines intersectionality with environmentalism.

“When striving to become better environmentalists, it’s also important to consider what communities are more likely to be exposed to the ramifications of climate change the fastest," she wrote in an article for The Good Trade.

"It’s important to take into account which communities are already struggling to be protected equally by environmental laws so they can have equal access to a safe environment. Our votes and advocacy can help change this."

@intersectionalenvironmentalist scrap shirts from the pre-sale fundraiser are finally shipping this week 🦋🌞 Thank you @east.west.shop for sustainably repurposing these scrap Tees from Milton, who has a Black owned scrap house in Compton, Ca with shirts and fabrics that would otherwise have gone to landfills. Through this sale we’re giving these shirts a new life and I can’t wait to see all the photos of people in their shirts. I’m shipping these out from my house, so it’s taken a little while and thanks everyone for your patience but I’m so excited for everyone who ordered. Just looked at all the shirts and they’re SOOO cute. We’ll be doing another scrap t drop soon. 🌱 thank you everyone who made this a reality. #intersectionalenvironmentalism #sustainablefashion #lowwasteliving

It’s 🌍 World Clean up day (which should be everyday!) Just a friendly reminder to reduce your waste, pick up the crap you see, dispose of it properly and get educated and curious about our natural world. When you understand you become more connected and when you are more connected you give more 💩! Yes that’s me lying on a beach filled with rubbish on Curaçao 🇨🇼 ☹️ #plasticpollution @oceanconservancy @garnierau
