Liberal Foundations and the Environmental Movement have depended upon each other for decades, especially since the first Earth Day in 1970 which is often recognized as the birth of the modern environmental movement. Scores of foundations provide hundreds of millions of dollars a year to non-profit tax-exempt environmental organizations. The philanthropists and staffmembers of these foundations have formed a myriad of inter-locked "key funder groups" that include the following:
- Health and Environmental Funders Network, 
- The Consultative Group on Biological Diversity, HEFN's parent organization 
- The Environmental Grantmakers Association, 
- The Funders Network on Smart Growth and Livable Communities, 
- The Sustainable Agriculture and Food Systems Funders, 
- Grantmakers In Health, 
- Funders Network on Trade and Globalization, 
- The Funders Workgroup for Sustainable Production and Consumption,
