That link 404s. Also, it's pretty suspicious that the website has no information about the nonprofit entity or its officers. Is it a 501(c)3? I can't tell. So I can't look it up on Charity Navigator or anything. It's very sketchy.
Came up on Charity Navigator for me, searching by name. No rating, but it says they are a 501(c)(3).
This non-profit is not a scam. They have done some well documented work to protect the Las Piedras Region, they are running a ranger program covering 55,000+ acres of rainforest working with the local communities and have partner with established philanthropies. See for instance the involvement of Age Of Union: https://www.ageofunion.com/feature/film-the-heart-of-a-missi... or some of the features about the work on ABC: https://youtu.be/8FAbqkaI9HY
Criticism is useful, but perhaps researching thoroughly before make wild claims like these can help. I invite people to do their own research.
