We are a think tank dedicated to figuring out the best ways to make the world a better place.

Rethink Priorities is a research organization that conducts critical research to inform policymakers and major foundations about how to best help people and nonhuman animals in both the present and the long-term future.

Our research spans everything from animal welfare to the threat of nuclear war. We explore neglected but promising areas to improve the world and try to further build the community of researchers working on understanding how to do this most effectively.

If you'd like to support one of our fiscally sponsored projects (e.g. Epoch), you can give via Every.org, and let us know how to allocate your gift at info@rethinkpriorities.org.

We want to make life better for wild animals.

We are dedicated to finding evidence-backed ways to improve the lives of animals in the wild.

We depend on individual donors to help us make life better for wild animals. To a small nonprofit working hard on a big problem, your support is more crucial now than ever!

Wild Animal Initiative

We are New Harvest, the cellular agriculture nonprofit. We’re growing meat, milk & eggs from cells instead of animals.

New Harvest was founded in 2004 to support the development of cultured meat (AKA “lab-grown meat”) and other cell culture-based foods. 

Our mission is to ensure cellular agriculture delivers on its promises to create a more equitable & sustainable food system by ending our dependence on animal agriculture. 

We fund public research and industry-wide initiatives to accelerate scientific breakthroughs and steward this tech toward making the world a better place.

Developing the roadmap for a sustainable, secure, and just global protein supply 🧫🌱


Check out what your support makes possible at gfi.org/your-impact. 

The Good Food Institute (GFI) is a global network of nonprofit organizations developing the roadmap for a sustainable, secure, and just protein supply. Industry alone will not meet this challenge at the scale or speed we need. GFI is accelerating the transformation of the food system by identifying solutions and mobilizing resources to make alternative proteins the default way meat is made.

GFI is a network of nonprofits around the world strategically based in the most critical economies for alternative protein advancement. In Asia, Europe, Brazil, India, Israel, and the U.S., GFI’s teams are mobilizing the international community to use markets and technology to replace harmful practices with ones that are better for the climate and biodiversity, for food security, and for global health.

GFI’s Focus
As a nonprofit, GFI is uniquely positioned to accelerate the transition to alternative proteins by focusing on three programmatic priorities:

-Cultivating a strong scientific ecosystem | GFI’s science and technology teams map out the most neglected areas that will allow alternative proteins to compete on taste and price. GFI meets these challenges by developing open-access research and resources, educating and connecting the next generation of scientists and entrepreneurs, and funding research that benefits alternative protein development across the sector. 

-Influencing policy and securing government funding | GFI’s policy teams ensure that alternative proteins are a part of the policy discussion around climate change mitigation and global health. In every region where GFI has a presence, teams advocate for government funding and incentives to transition to alternative proteins and are paving the way for the approval of novel proteins such as cultivated meat.

-Ensuring industry prioritizes alternative proteins | GFI’s corporate teams are creating a transformation of our global meat supply. GFI works to replicate past market transformations by showing companies of all sizes, from startups to multinational corporations, how alternatives to animal products can be profitable while meeting environmental, social, and governance goals.

Reimagining meat
The very real threats of climate change, global food insecurity, antibiotic resistance, and pandemics require us to imagine a different future of food. Alternative proteins are the solution that will securely and sustainably feed the world.

GFI’s global community of scientists, policy experts, and corporate specialists are creating a world where alternative proteins are no longer alternative.

StrongMinds provides life-changing mental health services to women in Africa using innovative community-based group therapy.

According to the WHO, depression is the leading cause of disability worldwide, and is a major contributor to the global burden of disease. In Africa, an estimated 66M women have depression and 85% have no access to treatment. Since 2014, StrongMinds has treated over 200,000 individuals for depression symptoms, with 80% measuring as depression-free after therapy. When a woman recovers from depression, she is more engaged in the community and her economic activity increases. Her family eats more meals and her children go to school more often. When you invest in mental health, you invest in the future of an individual, their family, and their community.

One of GiveWell's top charities for the past several years, AMF provides anti-malarial bednets to people in need. 

From Givewell: 
What do they do? AMF (againstmalaria.com) provides funding for long-lasting insecticide-treated net (LLIN) distributions (for protection against malaria) in developing countries. (More)

Does it work? There is strong evidence that distributing LLINs reduces child mortality and malaria cases. AMF conducts post-distribution surveys of completed distributions to determine whether LLINs have reached their intended destinations and how long they remain in good condition. AMF's post-distribution surveys have generally found positive results but have some methodological limitations. (More)

What do you get for your dollar? We estimate that the cost to purchase and distribute an AMF-funded net is $4.95, or $4.65 excluding in-kind contributions from governments. The numbers of deaths averted and other benefits of distributing LLINs are a function of a number of difficult-to-estimate factors, which we discuss in detail below. (More)

Is there room for more funding? We believe that AMF is likely to be constrained by funding. We estimate that AMF could use up to an additional $37.8 million to support LLIN distributions that will occur between now and late 2023. 

AMF is recommended because of its:

Focus on a program with excellent evidence of effectiveness and cost-effectiveness.
Processes for ensuring that nets reach their intended recipients and monitoring whether they remain in homes and in good condition over the long-term.
Room for more funding – we believe AMF will be able to use additional funds to deliver additional nets.
Transparency – AMF shares significant information about its work with us and we are able to closely follow and understand its work.
