For the last 30 years or so, 75% of the insects have disappeared from Europe. Entomologist Lundgren is grieving that it is 'the worst mass extinction the Earth has ever experienced.'

Neonicotinoid is an endocrine disrupting chemical that kills insects and plants, which will then destroy biodiversity and eventually become a threat to humanity. It is frightening to see that the continuing testimonies and accusations made by researchers, journalists, environmental organizations and farmers dissipate in front of the huge capital of a multinational pesticide manufacturer.
