Wildlife Defenders

Wildlife Defenders are part of a growing grassroots community speaking up for nature. This advocate network provides opportunities for individuals to utilize a range of advocacy tactics to support our imperiled wildlife, cherished landscapes, and the cornerstone conservation laws that protect our environment. 

In order to protect the planet, and our own future, we need to rise up and demand action on biodiversity loss, climate change, and all the environmental challenges we face.
