I thank my hon. and gallant Friend for his intervention. The treaty does not yet go far enough on plastic pollution, and I hope that the countries of the world will bring their best endeavours to achieving an international agreement in that regard. So far, sadly, those negotiations have not succeeded. I also want to recognise the serious, constructive work of our Liberal Democrat peers. They chose not to delay ratification, but they worked hard to strengthen the Bill. Lord Teverson pressed Ministers on enforcement gaps, flags of convenience, illegal fishing and human rights at sea, reminding us that the high seas cannot be a legal vacuum for either nature or people, and Baroness Miller of Chilthorne Domer pushed strongly on plastic pollution, especially the plastic pellets that now turn up throughout the marine food chain. Those issues have not gone away, and they now form the implementation agenda. As Lord Teverson observed during the debates in the other place, this may be one of the last major environmental agreements that we see from the United Nations for some time, given this era in which respect for international law appears to be under strain in a way that we have not seen for many decades. That makes the treaty not just important but precious. We are under a moral and existential obligation to make it work. This ratification must be the start, not the finish. If the UK wants to lead, the Government should aim to arrive at the first Conference of the Parties with a clear plan for implementation, and I suggest that the plan should include the publication of a proper implementation road map including timelines, responsibilities and funding, so that delivery does not drift. We should back our world-leading scientific institutions, such as the National Oceanography Centre, the British Antarctic Survey and the Centre for Environment, Fisheries and Aquaculture Science. They should be fully supported to provide the evidence, training and technology transfers on which this treaty depends. We should strengthen enforcement using our satellite-monitoring capability and our experience in monitoring vast protected areas in the overseas territories. As a priority, we should get our own maritime house in order. We cannot in good conscience call for protection overseas while allowing destructive practices like bottom-trawling in our own MPAs. Credibility must start at home. At a time when multilateral co-operation often feels fragile, this treaty shows what is still possible when countries work together to protect the global commons. The Liberal Democrats will support this Bill, but future generations will not judge us on whether we ratified the treaty; they will judge us on whether the oceans are healthier because we did something. Let us match warm words with hard action, and show that Britain still leads when it matters, not just by signing agreements but by protecting the blue parts of our planet, which give us food to eat and oxygen to breathe. To quote Sir David Attenborough, who turns 100 this coming May: “If we save the sea, we save our world.”
