I agree with my hon. Friend that the treaty can help to provide clarity about previously unregulated areas. Many countries have already ratified it, which shows that ocean conservation really can unite us where, in the past, there has been disunity. While I welcome the speed with which the Government have introduced the Bill following the Climate and Nature Bill, thus giving us a seat at the table at the first ever ocean COP next year, it is a little disappointing that the UK was not one of the first 60 nations to ratify the agreement. We hope to be a country that leads on climate diplomacy, so we should not arrive late at the crucial environmental treaty of the decade. While many of our colleagues are in Belém, and with the world preparing for that first ocean COP, the UK must demonstrate not only that it supports global ocean governance in theory, but that it is prepared to deliver it in practice. It is also vital to recognise that the health of our oceans depends on the health of our land-based environment; one cannot heal without the help of the other. We need to decrease our carbon emissions on land if we are to slow ocean acidification, which threatens plankton, ecosystem health, and the millions of people whose lives and livelihoods depend on the ocean. This responsibility starts at home. That is why the Liberal Democrats have long been pushing for the strongest possible marine environmental targets, both domestically and internationally. If we want credibility internationally, we need coherence domestically. Our own marine protected areas must live up to their name, which means ending destructive practices such as bottom trawling and implementing a clear, science-driven ocean strategy that rises above and goes beyond departmental silos and party-political lines. A strong stance on the high seas will ring hollow if our waters remain vulnerable. The public understand that, the environmental community understand it, and I know that many Members on both sides of the House understand it too. I join my Liberal Democrat colleagues in calling for a coherent oceans policy that joins up our commitment to international waters with stronger protections at home. As I draw to a close—[Hon. Members: “Hear, hear!”] I am getting there! Let me just say this. If we choose to pursue a strategy of high ambition, the UK can once again be a leader in global ocean protection, championing the first generation of high-seas sanctuaries, pushing for robust monitoring and enforcement, supporting small island states, and ensuring that the benefits of marine science are shared fairly. So yes, the Liberal Democrats welcome the Bill. It enables the UK to participate fully in the new regime for marine scientific resources, for marine protected areas, and for stronger environmental impact assessments. It is necessary, but it is not sufficient. The work that follows will determine its true legacy, and I trust that the Government will continue to draw on the support and perspectives of Members on both sides of the House to secure the wellbeing of the oceans for generations to come.
