We venture out into the big blue to check out the latest developments in Marine Protected Areas - or MPAs - those areas of the ocean set aside to let wildlife recover and thrive. Hot off the press, a new report launched in Nagoya tells us how many MPAs there are globally, where they are, and how much of the ocean they cover. Have we reached the 10% target yet? Plus we find out about a new generation of MPAs soon to appear around the UK coast and track down bottlenose dolphins and a gaggle of sea birds in a marine reserve off the Welsh coast.
