16:00 Mr Philip Hollobone (in the Chair)

The BBC’s “Blue Planet II” and Sir David’s stark warnings about the threats posed to the world’s oceans from over-fishing, plastics and, of course, climate change will stand for a very long time as a beacon of all that is wrong in our oceans, but it is also a clarion call for “action this day”, as Churchill would have put it. It is a call to all of us in this House to do what we can to lead the world in a variety of environmental initiatives, including taking steps to protect the waters around Great Britain, Northern Ireland and our 14 overseas territories.

However, before dealing with that, it is worth noting that my right hon. Friend the Prime Minister recently reaffirmed our commitment to tackling climate change and my right hon. Friend the Secretary of State for Environment, Food and Rural Affairs committed us to taking action on plastics in the oceans. Both those initiatives are very much to be welcomed. The Wildlife Trusts, among others, have called for the Government to develop a national marine strategy to safeguard the cleanliness and biodiversity of our own territorial waters after we leave the EU.

As chairman of the all-party parliamentary group for the polar regions, I take a particular interest in South Georgia and the South Sandwich Islands, which sit on the cusp of the Southern ocean and Antarctica. There, the UK has a real responsibility. After all, it was largely our whalers and sealers who wrought so much of the appalling environmental damage there in the 18th and 19th centuries. They left behind something of an environmental catastrophe, particularly on South Georgia. We also have a huge responsibility because South Georgia and the South Sandwich Islands is an area of such outstanding scientific importance, both for the study of marine ecosystems and for monitoring the effects of climate change, sitting as it does on the cusp of two great oceans.
