SDG #15 - Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss.

The Center for Biological Diversity believes that the welfare of human beings is deeply linked to nature - to the existence in our world of a vast diversity of wild animals and plants. Because diversity has intrinsic value, and because its loss impoverishes society, we work to secure a future for all species, great and small, hovering on the brink of extinction. We do so through science, law, and creative media, with a focus on protecting the lands, waters, and climate that species need to survive. The Center has six program areas: Biodiversity, Climate, International, Oceans, Wildlands, and Urban Wildlands. The Center looks forward to a future of continued expansion, creativity, and no-holds-barred action on behalf of the world's most critically endangered animals and plants.

The American Forest Foundation works on-the-ground with families, teachers, and elected officials to promote stewardship and protect our nation's forest heritage. AFF is committed to creating a future where North American forests are sustained by the public that understands and values the social, economic, and environmental benefits they provide to our communities, our nation, and the world.

Founded in 1999, the Amazon Conservation Association (ACA) works to conserve the biological diversity of the Amazon. We work to protect biodiversity by studying ecosystems and developing innovative conservation tools to protect land in the region while supporting the livelihoods of local communities. We work by forging ties with governments, nonprofits and people who depend on the rainforests for their livelihood, with the goal of saving rare species and habitats and learning from the land. Scientific research guides our approach, which strives for concrete, measurable achievements.

WildAid's mission is to end the illegal wildlife trade in our lifetimes. WildAid works to reduce the demand for illegal wildlife products, and to promote energy conservation, via global public awareness campaigns. WildAid also strives to create model field conservation programs and to strengthen marine protected areas around the world.
