Caring about the planet often starts small: bringing your own bag, skipping single-use plastic, biking instead of driving. But sometimes, you want to go a little further – to support the bigger movements and organizations that are protecting ecosystems, pushing for policy changes, and defending communities impacted by climate change.
And the great thing is, you don’t have to give hundreds of dollars to make a difference. Even a small monthly donation helps keep these organizations running. And if money is tight, there are so many other ways to help, like following them on social media, sharing their work, or signing petitions all help keep the momentum going.
Here are 10 amazing organizations worth checking out:
1. Greenpeace
One of the most well-known environmental groups, Greenpeace campaigns for issues ranging from ocean conservation to renewable energy. They’ve been at the forefront of global climate action for decades, and their direct action campaigns are often what gets people talking.
💚 How to support: You can become a monthly supporter starting at around $5/month. While monthly donations help, so does signing petitions, volunteering, or even just amplifying their campaigns online.
This global network works on everything from protecting pollinators to fighting for climate justice. They focus on grassroots action and policy change, making them a strong voice for communities often left out of environmental conversations.
💚 How to support: Donations, joining local chapters, or following their campaigns on social media. Membership starts at about $25/year, or you can give monthly from around $5.
Best known for its work protecting endangered species, WWF also tackles climate change, deforestation, and sustainable farming. You’ve probably seen their iconic panda logo, which is recognizable worldwide.
💚 How to support: Symbolic “Adopt-an-Animal” programs, monthly donations, or simply choosing WWF-certified products. “Adopt an Animal” programs start at $25, memberships around $60/year, or monthly gifts as low as $5.

5. 350.org
This grassroots climate movement was founded by writer Bill McKibben and has grown into a global force. They organize climate strikes, campaigns against fossil fuel projects, and community action around renewable energy.
💚 How to support: Join their online campaigns, sign petitions, share events, or sign up as a volunteer. Recommended recurring donations start at $5/month.
Their little green frog logo might look familiar from coffee or chocolate packaging. The Rainforest Alliance works with farmers, foresters, and businesses to make supply chains more sustainable, while protecting rainforests and the communities that live in them.
💚 How to support: Look for their certified products or raise awareness by sharing their educational resources. You can give one-time or monthly donations; monthly giving starts around $5/month.
If the ocean has your heart, this one’s for you. Ocean Conservancy organizes cleanup efforts worldwide and advocates for policy to reduce plastic pollution, protect coral reefs, and combat climate change’s effects on marine ecosystems.
💚 How to support: Join or organize a local cleanup or become an “ocean advocate” by amplifying their work. For donations, memberships start at $25/year, or you can give monthly from $5.
8. Earthjustice
Their motto says it all: “Because the Earth needs a good lawyer.” Earthjustice is a nonprofit law organization that uses legal action to fight for clean air, clean water, and healthy communities.
💚 How to support: Donations are their main need, but following their cases and spreading awareness makes a big difference too. For donations, you can give one-time or recurring gifts, with monthly support starting around $10.
9. Sierra Club
One of the oldest grassroots environmental organizations in the U.S., Sierra Club promotes outdoor access and conservation while pushing hard for renewable energy and climate policy reform.

And last but not least…
10. Local & Community Organizations
While global groups are important, don’t forget the small, local nonprofits in your area. From land trusts to zero-waste shops to neighborhood advocacy groups, these often-overlooked organizations are doing incredible work right where you live.
💚 How to support: A small monthly gift (often as low as $5), volunteering, or simply showing up to community events makes a huge impact.
Supporting these organizations is about more than money. It’s about amplifying their work, joining their community, and standing up for the planet in ways that feel manageable for you. Whether that’s $5 a month, a Saturday spent at a cleanup, or a quick repost on Instagram, it all adds up.
