ReWorld enables donors to make a permanent, measurable impact on the planet. With a one time donation, you can select and protect part of the Amazon rainforest forever. Your investment goes directly to acquiring and preserving threatened areas, and you receive annual, accurate metrics of the impact you're making: think number of trees planted, tons of carbon removed, and endangered species protected. Our first project is with Proyecto Titi, a highly regarded Colombian Conservation NPO with a 20+ year track record of success. 100% of your contribution will help Proyecto Titi create the world's first community-built tropical forest and biodiversity park in San Juan, Colombia. Home to the endangered critically endangered cotton-top tamarin, Proyecto Titi is working to reforest and protect this uniquely biodiverse region.
