environmentalists hero image

These environmentalists have founded their own organizations, created movements, and authored some of the most important books on climate.  

Each one of these advocates has inspired me at different points in my own work and I hope you’ll find someone here on this list that will inspire you, too. 

In this post, I’ll be introducing you briefly to who each environmentalist is, where they’ve focused their efforts, and as well, how you can best start to sample, engage with, and support their work. 

It’s thanks to the leadership that many of these people exhibit as to why the environmental movement not just has hope, but continues to gain it despite seemingly overwhelming opposition. 

From leading protests, to authoring manifestos, to influencing public policy, here’s 19 environmentalists who inspire all of us to build a more sustainable and habitable future for all.

Third Act is an organization founded to mobilize people over the age of 60 for action on climate and racial justice. 

Bill is responsible for writing some of the earliest books on global warming for the general public, most notable perhaps, The End of Nature

Paul is in the business of proposing climate solutions. He believes that while a challenging task, the task to regenerate and repair our planet should be an inspiring one. 

Paul’s latest organization, Project Regeneration, is about providing the action plan for “all levels of society” to take part in ending the climate crisis and creating a future that prioritizes all life in any/all decisions and actions.

Greta Thunberg is an environmental activist I’m sure we all recognize by now. Even still, this list wouldn’t feel complete without her. 

Greta’s public climate activism began with her school strikes for climate back in 2018 when she was just 15 years old. At the time, she hadn’t yet rallied support of classmates or peers, but she continued along herself. 

But quickly enough (by late 2018), Greta’s demonstrations inspired others all over Europe. Apparently from that very first demonstration in August, by October of the same year, 20,000 students had likewise demonstrated in 270 towns and cities around the world (source).

Since then Greta has continued to advance the climate movement; she’s received dozens of awards, spoken at countless climate events and conferences, and continues to inspire people of all ages to join in the fight to save the planet.

They are on a mission to change incentives throughout the typical agricultural supply chain, putting ecological health and equity for those who most attentively care for it (like those farmers) at the forefront.

Environmentalists Who Inspire Us to ACT

Every single one of these environmentalists and advocates offers a unique reason to admire them. 

But surely, admiration, or inspiration isn’t the end goal. 

It’s courage. It’s boldness. It’s action. 

Every one of us needs to be active if we’re to avert catastrophe and create a habitable and equitable planet for all of us, now and for generations to come. 

It’s not about doing the one thing that addresses the climate crisis, it’s about doing something. 

And doing something that feels like the right thing for you. 

Yes, use the examples of climate leaders and environmental activists I shared here for inspiration. 

But, specifically for the inspiration to find what gets and keeps you moving in the direction towards a sustainable, equitable, and just future for all.
