They would be a great starting point as they campaign against species extinction and habitat loss worldwide so you can find out lots of info about the issues, as well as the contacts of the projects if yu want to take it further.
Over the last 5 years they have worked with 30 projects on all seven continents. They also attended COP26, the major climate change conference hosted in Glasgow in 2021, one of only 15 organisations out of 6,000 applications invited to both display and attend as delegates.
