World Oceans Day 2021

Selaine Saxby Excerpts

Tuesday 8th June 2021 Westminster Hall

[Selaine Saxby (North Devon) (Con)]

I beg to move,

That this House has considered World Oceans Day 2021.

It is a pleasure to serve under your chairmanship, Mr Hosie. The Earth is a blue marble. Over 70% of its surface is covered by water, and the algae that live on the surface account for more than 50% of the oxygen we breathe. So far, the ocean has absorbed one third of all human-created emissions, and regulates our climate. Our oceans are too big and too important just to be the domain of MPs such as me, who are blessed with a constituency with a sea shore. The oceans are home to over a quarter of a million known species and another 2 million as yet unknown, and they are the main source of protein for more than 1 billion people.

United Nations World Oceans Day is a celebration of the potential of our sea, and this year’s theme is life and livelihood. Globally, fishing supported some 39 million jobs in 2018, and the UK’s fishing industry alone is worth almost £1 billion to our economy. In my North Devon constituency, many local businesses and families rely on the maritime economy, and we need to revert to sustainable fishing practices to ensure that we use those precious resources in the best way possible. Additional jobs, fish and associated economic benefit could be derived if our fish stocks were restored to their maximum sustainable yield.

Conservative Governments have led the way for the UK to become a global ocean champion, with our extensive network of marine protected areas. However, we could make use of our post-Brexit freedoms to ban bottom trawling. Research suggests that emissions from bottom trawling alone could be as high as those from all UK agriculture.

Why does that matter? Our seabeds are significant carbon stores, or sinks. When they are disturbed by bottom trawling or dredging, or even by anchors being thrown overboard, the stored carbon becomes resuspended in the water, and potentially escapes back to the atmosphere as CO₂. Over 200 million tonnes of this blue carbon are stored on the UK’s ocean floor—a third more than is held in our stock of standing forests.

The role of coastal and marine habitats in drawing down carbon dioxide from the atmosphere and storing it in seabed, sediment, seaweeds, salt marshes and seagrass beds has been somewhat neglected. Increasing blue carbon habitats could result in a reduction of carbon in our atmosphere, while reducing the disturbance of the seabed ensures that it remains stored. As a Marine Conservation Society blue carbon champion, I believe that if we are to meet net zero by 2050, we must consider blue carbon part of the solution, not to mention integrating it in our carbon accounts. Along with other hon. Members, I recently wrote to Lord Deben, the chair of the Climate Change Committee, to ask him to look into the feasibility of making that happen.

My North Devon constituency is home to the first UNESCO biosphere, and today is the 50th anniversary of the Man and the Biosphere programme. Our world-leading biosphere conducts a wide range of ongoing projects, including those investing in seaweeds, seagrass and salt marshes. I am truly fortunate that I spend my weekends in and on the sea, surfing and gig rowing. I live and breathe the ocean. Sir David Attenborough’s legendary “Blue Planet” brought the ocean to all our living rooms, and we now need to link that passion to action to ensure that it is there for future generations.

No wonder 85% of people in England and Wales consider marine protection important to them. Take whales, for example: not only are they delightful to watch when we are lucky enough to see them, but they are brilliant tacklers of climate change. Each great whale sequesters around 33 tonnes of carbon dioxide on average in their lifetime, which is equivalent to the carbon sequestration of almost 1,400 trees.

We need to ensure that we are all aware of the value of our oceans and what lives within them, and be aware that, while the benefits of rain forests are so widely taught, our oceans and blue carbon are absent from far too many curriculums.

I am proud that the UK, through leading the Global Ocean Alliance and co-chairing the High Ambition Coalition for Nature and People, is pushing to protect at least 30% of the global ocean in marine protected areas and through other effective area-based conservation measures by 2030—the 30by30 target.

It is great news that this morning the Government have announced plans to pilot highly protected marine areas in English waters, creating sites where all activities that could have a damaging effect on wildlife or marine habitats would be banned. The independent Benyon review concluded that such HPMAs would have an important role to play in helping the marine ecosystem to recover. The Government have my full support in taking those steps.

Biodiversity is also crucial. With 90% of big fish populations depleted, and 50% of coral reefs destroyed, we are taking more from the ocean than can be replenished. As the UN states when referencing World Oceans Day:

“To protect and preserve the ocean and all it sustains, we must create a new balance, rooted in true understanding of the ocean and how humanity relates to it. We must build a connection to the ocean that is inclusive, innovative, and informed by lessons from the past”.

Connect to the ocean we must. I frequently collect litter on our beaches and am horrified by the volume of plastics, microplastics and nurdles on North Devon’s beautiful beaches. The tragic situation with the container ship in Sri Lanka last week—it caught fire and spilled its cargo into the ocean—has brought nurdles something of an unwanted fame, but it highlights the fact that we are indeed shipping those pellets around the world in containers that end up in our seas. Is that what we want? If not, what are we going to do to change it?

Plastic pollution is visible and tangible, and we feel we can do something about it by picking it up, but so much of what is going on in our oceans is not visible. Sewage pollution is another challenge along my constituency coastline. I was one of the MPs to support the Sewage (Inland Waters) Bill tabled by my right hon. Friend the Member for Ludlow (Philip Dunne), and I am delighted to see so much of it incorporated in our landmark Environment Bill, which yesterday received its Second Reading in the House of Lords.

I also hope that introducing the debate will reduce the pressure on my inbox, as I receive an abundance of emails from constituents linked to the Surfers Against Sewage campaign each time the water quality is reduced in North Devon. I very much hope further steps will rapidly be taken to reduce the discharge into our rivers, which ultimately reaches our oceans.

Blue carbon is part of the solution, not part of the problem, when it comes to achieving net zero. I hope that today’s debate offers a chance to focus not just on what we have achieved, but on how much more there is still to do to restore our oceans and to optimise their link to our lives and livelihoods.

[Stewart Hosie (in the Chair)]

Before I call Kerry McCarthy, I should say that colleagues will be aware that there are around 10 Back Benchers who want to speak. If Members take five minutes each, we will all get on great.

[Selaine Saxby]

I am glad to see that there is such wide support for protecting and restoring our oceans on this World Oceans Day, in what I hope will be a marine super-year. Colleagues are right that we can do more to reach 30by30, to recognise the contribution that blue carbon can make to achieving net zero, and to highlight the importance of our oceans to lives and livelihoods.

Question put and agreed to.

Resolved,

That this House has considered World Oceans Day 2021.
