Lords ChamberMy Lords, when genetic technology is mentioned, many of us still get alarmed because we associate it with GMOs and remember our press in an unedifying moral panic using dramatic headlines such as “Frankenstein foods”. However, with precision breeding, we need to look deeper than the headlines and the shroud-waving, shrill screams of the “anti” campaigners, which are more often semantic than scientific. I believe many are playing on popular misconceptions and a general lack of knowledge about the science of genetic improvement or breeding.
What is breeding? My noble friend Lord Roborough called it “imprecise”. At its most basic, it is the random recombination of literally hundreds of thousands of genes of living organisms. There is nothing new to us in that; us humans have been doing it for 10,000 years. Almost every morsel of our food is genetically modified now. Thus, there is nothing particularly natural about farming. For example, wheat is not a natural food. It is a wheat grain that has been genetically modified from grass. Equally, my noble friend Lord Holmes of Richmond’s guide dog is a genetically modified wolf. There is nothing new in it.
As it involves such a random recombination of genes, I have heard breeding described as like playing a fruit machine—not with three or four reels, but with several hundred. Over time, as our understanding of plant genetics has increased, the process of breeding has become more sophisticated, with each new advance improving the plant breeder’s chances of hitting the jackpot. Much of the success of plant breeding, for example, is based on invasive laboratory-based techniques such as protoplast fusion, doubled haploidy or somaclonal variation, to name but three. All of them, it could be argued, are as difficult to understand as “precision breeding”, if not more so. All the questions the noble Lord, Lord Winston, raised about precision breeding could equally be asked about what is happening now.
Despite these advances, plant breeding remains a lengthy, research-intensive process. It can take up to 15 years to develop each new crop variety. Precision breeding techniques such as gene editing allow scientists a tool to control adjustments to a living organism’s existing DNA, when these changes could occur in nature or in traditional breeding. That is worth stressing. The Bill is absolutely clear and precise that the changes could occur in nature or traditional breeding. As my noble friend Lord Jopling reminded us, it does not permit the introduction of a new gene from another species. That is why the result is not a GMO. Its great advantage is that it speeds up the process considerably by many years in the same way that keyhole or minimally invasive surgery has transformed the ordeal of a full-blown surgery.
By taking products which would equally have been bred conventionally out of the scope of the GMO rules we inherited from the EU, the Bill will realign our regulations with the mainstream approach taken elsewhere in the world. Countries such as Australia, Japan, Canada, Brazil, Argentina and the United States do not treat the products of these techniques as GMOs but rather as conventionally bred products. The noble Baroness, Lady Jones of Whitchurch, was right that there are now strong indications that the EU will revise its position and follow the example of this Bill.
Some argue that precision breeding is unnatural. Many of us enjoy a glass of craft brewed ale. It is often made from golden promise barely, as was most Scotch whisky in the 1970s and 1980s. This excellent barley was created by bombarding seeds with gamma rays from cobalt-60 isotopes in a nuclear reactor to introduce random mutations, then picking out the seeds with a desirable character. What is natural about that? I have not found a beer drinker or a Scot who likes a 40 year-old malt who has changed their mind at all when I mention the origin of their beer or whisky.
Exempting gene-edited products from GMO provisions does not mean that they are no longer subject to regulation. I welcome that the UK has well proven and robust regulations to improve new plant varieties, underpinned by the general requirements of food safety, novel food and environmental protection laws. However, we will need to look closely at Part 3 of the Bill, as the current performance of the Food Standards Agency in regulating GM feed import dossiers does not inspire confidence that implementation of these provisions will be either light touch, low cost or proportionate.
The first tranche of GM feed import applications approved by the FSA lagged behind the EU by more than 12 months. What action is my noble friend the Minister taking to ensure that the FSA is not allowed to stifle the good intentions of the Bill through bureaucracy and drive up costs so high that it is uneconomical for the smaller seed merchants producing less popular crops such as vegetables or for farmers to grow new varieties competitively? We do not want to be in the hands of only the international firms and to have to import seeds when we could produce our own.
I agree with the noble Earl, Lord Devon, that precision breeding will benefit our environment hugely, as it will help minimise our environmental footprint by enabling increased and better production of food. It was very useful for the House to hear the wise words of the noble Lord, Lord Cameron of Dillington, about Africa. Everybody and every country in the world stand to benefit from properly regulated precision gene editing, but will my noble friend the Minister confirm that in Defra precision breeding will not be regarded as a single, silver-bullet solution? It needs to be adopted as part of a broad toolbox of technologies and management approaches incorporated into farming systems to encourage sustainability, increase food production under climate change challenges and protect unproductive areas for the benefit of conservation. It should not allow farmers to farm more productively yet shirk their responsibility to farm sustainability or dedicate more land to nature and to maintain the high animal welfare we already have.
The noble Lord, Lord Trees, was right to say that this Bill is a game changer. It deserves our support.
