Wildscreen’s mission is to convene the best filmmakers and photographers with the most committed conservationists to create compelling stories about the natural world; that inspire the wider public to experience it, feel part of it and protect it.
It says that one of the ways it does this is by helping other conservation charities to make films about their work as films and photographs have the ability to speak to everyone and are one of the most effective tools we have to spread conservation messages to as many people as possible.
