George Monbiot has a very good article on Neonicatinoid poisoning being the nu DDT, our environment, government support support for such poisoning using discredited, flawed studies, etc. Strange that I missed it first time.
It’s the new DDT: a class of poisons licensed for widespread use before they had been properly tested, which are now ripping the natural world apart. And it’s another demonstration of the old truth that those who do not learn from history are destined to repeat it.
It is only now, when neonicotinoids are already the world’s most widely deployed insecticides, that we are beginning to understand how extensive their impacts are. Just as the manufacturers did for DDT, the corporations which make these toxins claimed that they were harmless to species other than the pests they targeted. Just as they did for DDT, they have threatened people who have raised concerns, published misleading claims and done all they can to bamboozle the public. And, as if to ensure that the story sticks to the old script, some governments have collaborated in this effort. Among the most culpable is the government of the United Kingdom.
As Professor Dave Goulson shows in his review of the impacts of these pesticides, we still know almost nothing about how most lifeforms are affected. But as the evidence has begun to accumulate, scientists have started discovering impacts across a vast range of wildlife.
Slightly later edit: The article is well worth reading and I should have quoted this section. (and it should be Neonicotinoid in the title.)
Most people who read this newspaper will be aware by now of the evidence fingering neonicotinoids as a major cause of the decline of bees and other pollinators. These pesticides can be applied to the seeds of crops, and they remain in the plant as it grows, killing the insects which eat it. The quantities required to destroy insect life are astonishingly small: by volume these poisons are 10,000 times as powerful as DDT. When honeybees are exposed to just 5 nanogrammes of neonicotinoids, half of them will die. As bees, hoverflies, butterflies, moths, beetles and other pollinators feed from the flowers of treated crops, they are, it seems, able to absorb enough of the pesticide to compromise their survival.
