Naturalist Chris Packham presents a hard hitting personal take on what's going wrong - and sometimes right - with our marine wildlife and its conservation. Chris travels to Lundy to see how a no-take zone there has benefited undersea creatures and to Lyme Bay to see the impact of a scallop dredging ban. He finds conservationists and fishermen at loggerheads over proposed new marine conservation zones that may help to protect wildlife in the future.
