Peter Chadwick is a conservationist with a vast wealth of knowledge in both the marine and terrestrial worlds, ranging from law enforcement and reserve management, to conservation photography, wildlife ranger training and development, and even the intersection of conservation and human rights strategy and training. We chat to Peter about the world of marine rangers, the crucial role they play in protecting ecosystems, the challenges they face on a day-to-day basis, and what is being done to support these courageous men and women on the frontlines of conservation.
