2020VISION: Britain's most ambitious nature photography project 2O2OVISION is the most ambitious nature photography initiative ever staged in Britain. It aims to establish in the public mind the crucial link between people's wellbeing and a wilder UK - to show that healthy ecosystems are not optional, but are something fundamental to us all. As such 20 of Britain's top nature and wildlife photographers have come together to document some of our country's ecosystems.

Photographer Alex Mustard comments: "Once in the water seals transform from blubbery blobs into bullet-like acrobats. This particularly curious ageing male with hardly any teeth remaining fancied my camera as a tasty snack. Up this close you realise seals don't have the sweetest breath. Britain's coastline holds 40% of the global grey seal population. Picture: Alex Mustard/2020VISION / Rex Features
