Colcom Foundation was created in 1996 to provide a forum for the examination and discussion of the major causes and consequences of overpopulation and its impact on environmental sustainability. "Over 70 organizations demand Colcom Foundation stop funding anti-immigrant groups: The Colcom Foundation is a private philanthropic foundation based in Pittsburgh and started by Mellon bank heiress Cordelia Scaife May. Colcom markets itself as an environmental organization and gives millions to local environmental causes, but the majority of its funding goes to immigration-restriction groups, including some that have been deemed hate groups by the Southern Poverty Law Center. A Drop Colcom Campaign press release points out how the Colcom Foundation was originally founded by Dr. John Tanton, an environmentalist and “avowed eugenicist who advocated for a majority white population in the U.S. and a sealing off of the U.S.-Mexico border to protect against what he called a ‘Latin onslaught.’” In 2017, the foundation gave more than $34 million to anti-immigrant groups, which was more than 80% of their total giving that year. Since 2005, Colcom has given more than $150 million to anti-immigrant groups, as well as a much smaller figure donated to Pittsburgh-area environmental nonprofits and other groups."
