My Lords, I congratulate the noble Lord, Lord Trees—he is my noble friend; I hope that I am allowed to use that term—on securing today’s important debate. I welcome those Members who are here to take part in it. Frankly, I wish that we had more debates of this kind in the Chamber. I will do my best to bear in mind what was said earlier about the time limit. The introduction from the noble Lord, Lord Trees, was masterly and comprehensive. I wish the Minister well in his maiden speech at the Dispatch Box.
I know that noble Lords have received useful briefings from organisations with an interest in this broad subject. I thank them all. I pay tribute to the valuable briefing from our own House of Lords Library and the briefing produced by POST in April last year. I recommend that today’s readers of Hansard should consult them all.
I want to use my time to convey some of the points raised with me by the Royal Society of Biology, in particular its science policy team. The House will know that the Royal Society of Biology is the major scientific society covering the biological sciences; I should draw the attention of the House to my entry in the register of interests as a fellow. The RSB submitted evidence to the UK Biological Security Strategy in 2022 and to the Emerging Diseases and Learnings from Covid-19 inquiry in 2023.
It is the view of the society that, in responding to threats to UK biosecurity, government policy-making should take into account all available evidence from all available sources, whether environmental or concerning human or animal health. Frankly, we cannot take a piecemeal approach to biosecurity because, if you do not consider the issue in the round, the risk is that you displace one problem with another. Action on one specific front is not going to be enough. The Government should optimise the use of evidence synthesis so that our society and its ecosystems, its health systems and the food, feed and fuel—even the construction material production systems—that we rely on are able to avert and be resilient to disease, biological attacks and other biological risks.
By construction materials I mean, for example, wood. The health of trees is of huge importance, especially when considering the threats from overseas; mention has already been made, quite rightly, of ash dieback. I think this is one of the reasons why Members have taken quite an interest in the recent Bill to facilitate the CPTPP: because of the biosecurity risks
that arise from trade in that part of the world. For example, a bacterium called Xylella fastidiosa—I hope I pronounced it right—has not yet been detected in the UK but is known to have been responsible for major outbreaks in Europe. It causes disease and plant death in more than 650 plant species, including crops such as plums, cherries, almonds, blueberries and rosemary. Other hosts include tree species such as oak, elm, ash and plane—all of which, as we know, we have here in the UK. Stricter measures are necessary, especially at our borders, to prevent the import of biosecurity risks.
Another risk that we should take extremely seriously concerns the indiscriminate use of antibiotics in animals, which is all too prevalent in parts of south and south-east Asia. I shall return to this in a moment.
It is fundamental that the evidence base used by the Government to decide their policy incorporates the One Health principles and that these are incorporated into future policy-making decisions. This is an important point that I would like to emphasise. The One Health principles are an integrated, unifying approach that aims to sustainably balance and optimise the health of people, animals and ecosystems. It recognises that the health of humans, domestic and wild animals, plants and the wider environment—including ecosystems—are closely linked and interdependent. The Government must co-ordinate their efforts with funders and other stakeholders to enhance and incentivise One Health research and education. They must also integrate One Health into their evidence base and take it into account alongside their long-term strategy to tackle current and future threats. One Health policy must not be solely human and animal focused but should encompass as broad a range of aspects as possible, including plants and other organisms, environmental factors and the interactions between these.
There are different types of threats to UK biosecurity. It is vital that the funding for and prioritisation of zoonotic diseases do not detract from resources focused on the continuing threat of other pandemics. Emerging infectious diseases in plant populations can seriously jeopardise food security, biodiversity and the natural environment, with serious health and economic consequences. Insufficient biosecurity measures have increased the risk of pandemics across species, including what you might call the silent pandemic of antimicrobial resistance, as well as hampering the treatment of current and emerging infectious diseases. I hardly need to tell your Lordships that AMR remains a major threat that faces us all. If we cannot keep one step ahead of nature’s ability to adapt and develop resistance to antibiotics, we will go straight back 200 years to the early 19th century, when a cut on your knee could lead to infection and death; to be more up to date, treatments that we now have for HIV, as well as hip and knee operations, would be too risky to attempt and deaths would soar as a result.
My time is coming to an end so I will finish by saying this: this biosecurity debate is one side of a coin that has climate change on the other. It will benefit us all if we understand how important that is because we have lots of threats facing us in this country, and biodiversity loss and climate change are two of the most important.
