From the BBC report:
"In 2011, environmental campaigners, the IUCN, established an international scientific taskforce on systemic pesticides to look into the impacts of these chemicals. The members have reviewed over 800 peer reviewed papers that have been published in the past 20 years. Their assessment of the global impact says the threat posed goes far beyond bees."
It is an agro-chemical industry lie there is no science behind the bans and concerns. They think that if they repeat this often enough, and scare us enough about food security they will be believed.
We have to accept that we cannot keep every last grain of food for ourselves. The end result will be a sterile land and no food. Nature is telling us we are finding our limits.
