How can photography help address the climate crisis? Can we document and raise awareness now? In the future will we travel mostly in virtual reality? Is photography actually adding to the crisis by luring us away to exotic places? We know photogrpahy can drive social change - so how do we use it for good? Picks of the week: Edward Burtynsky TED talk and gallery, 2019 Environmental POTY winners, J Henry Fair and our very own TFOP Instagram.
