New German research has found that insect numbers have plunged by 75% over 25 years, in nature reserves. It’s assumed the decline outside the reserves is greater. The Guardian reports on the issue here.
Germany is generally considered significantly better at conservation and environmental protection than Britain.
The cause isn’t determined but the chief suspects are the overuse of pesticides (specifically neonicotinoids) and lack of forage in surrounding farmland.
Watch for the usual pattern of denial, obfuscation and denigrating the research from the usual suspects.
