Bees: Neonicotinoids

Kerry McCarthy Excerpts

Wednesday 2nd February 2022 Westminster Hall

[Kerry McCarthy (Bristol East) (Lab)]

I congratulate my hon. Friend the Member for Plymouth, Sutton and Devonport (Luke Pollard) on securing the debate.

The note that the hon. Member for Sleaford and North Hykeham (Dr Johnson) ended on was interesting because the whole point of this debate is that the Government are not following the science. The expert committee on pesticides and the Health and Safety Executive have told the Government that the conditions for the use of these pesticides have not been met, and the Government have chosen to exploit a loophole and ignore the experts.

Those of us who were involved in the seemingly endless discussions on the Environment Act 2021, in pre-legislative scrutiny and Committees—at one point there seemed to be a Second Reading every other day—and on the Agriculture Act 2020, were always worried that the Government did not want to support the precautionary principle and did not want to see it embedded in law. That is why Labour Members tried to amend the Environment Act to give Parliament the power to scrutinise these decisions. The case has been made for that parliamentary scrutiny by several hon. Members today, but it was voted down by the Government.

We know how dangerous pesticides are to bees. I do not want to reiterate all the arguments, but we have heard that when exposed to neonicotinoids in low doses the bees’ immune systems are harmed, making them susceptible to disease. Neonicotinoids disrupt bees’ ability to navigate, forage and reproduce, and in high doses they cause paralysis and death. There is also research showing that pesticides become more dangerous when combined, including pesticides that are specifically marketed as safe for bees.

We have also heard why pollinators—as has been said, they include not only bees but flies, wasps, beetles, butterflies, moths and bats—are so important. Some 75% of our crop species require pollination. Pollinators are crucial in fertilising plants and sustaining our food systems. In China they have had to resort to pollinating fruit trees by hand because pollinators have been nearly wiped out by pesticide use. That should serve as a warning to us. As we have heard, there has been a drastic decline in pollinators here, too, falling by over 50% between 1985 and 2005.

The hon. Member for Brighton, Pavilion (Caroline Lucas) mentioned agroecology’s approach to farming. Organisations such as the Soil Association, which is based in Bristol, have been highlighting the dangers of pesticides and promoting alternatives for years. They argue that if nature is properly harnessed to pollinate crops organically and to deal with pests, rather than relying on destructive pesticides that harm biodiversity, crop yields would be higher. Evidence has shown that margins with wildflowers for pollinators increase crop yield.

The sugar beet sector has said that there will no longer be a need for neonics by 2023 if integrated pest management approaches can be adopted instead. As the hon. Member for Brighton, Pavilion said, what are the Government doing to support that as an alternative to a reliance on pesticides?

It is not just pollinators that are at risk from the use of pesticides. Otters were nearly wiped out in the 1970s due to pesticide use. Thankfully, otter populations have recovered since those pesticides were banned, but they are still under threat from other so-called “forever chemicals”, such as per- and polyfluoroalkyl substances.

[Sir George Howarth (Knowsley) (Lab)]

My hon. Friend is making a very well-informed speech, as always. There seems to be some doubt between Members as to where the balance of science lies. My hon. Friends the Members for Plymouth, Sutton and Devonport (Luke Pollard) and for Putney (Fleur Anderson) have both said that the science does not back the Government’s position. Does my hon. Friend agree?

[Kerry McCarthy]

I agree. We have heard from the experts and they have said that the case has not been made. I know that the Government have been quite dismissive of experts in the past, but that is the case. What is the point of asking for expert opinion if the Government do not abide by it? I suspect that in her response, the Minister will tell us that the Environment Act 2021 commits us to reversing biodiversity decline by 2030. Perhaps she could tell us how allowing the use of neonicotinoids in pesticides will help that? The Minister may also point out how the Agriculture Act 2020 rewards farmers who try to increase biodiversity on their farms. However, we heard in yesterday’s debate in this Chamber that the Government are making a mess of introducing ELMS.

Later this year, the convention on biological diversity will meet in China; it is very unclear what the Government hope to achieve from the UK’s participation. Perhaps it would be an idea to go along, promote the precautionary principle, and pledge to ditch the pesticides, protect our pollinators and genuinely promote biodiversity.
