The Global Youth Biodiversity Network (GYBN) is an international network of youth organizations and individuals from every global region who have united together with a common goal: preventing the loss of biodiversity and preserving Earth's natural resources.
GYBN is the official group for youth in the negotiations under the United Nation's Convention on Biological Diversity (CBD) and is recognized and supported by the CBD Secretariat. Presently, GYBN has 280 member organizations from 140 different countries.
GYBN USA works to mobilize youth to protect national biodiversity while expanding knowledge of the UN CBD global biodiversity targets. We do this by increasing knowledge of the CBD among youth activists in the USA, collaborating among youth groups around the country to magnify the impact of our collective voice, and attending CBD Conferences of the Parties alongside USA-based environmental organizations, state governments, and our federal government. GYBN USA is also working with states and the federal government to integrate ecological science into policy and independently commit to the UN CBD.
