What is the largest environmental group in America?



  1. 0 Votes

    The Sierra Club is known as the nation’s “oldest, largest, and most influential grassroots environmental organization.” There are plenty of other environmental groups and many of them are not limited to just the United States. Greenpeace, for example, is an international group and it is also one of the largest, most well-known organizations. If you want to see a list of the top 20 largest environmental groups in the nation based on membership, you can find it here. The list is alphabetized but I don’t think it tells you how many members are in each group.

    Hope this helps!
