Bees and other pollinators are harmed by certain pesticides.
An article in Nov 2017 from the Department for Environment said: 'Tougher restrictions on neonicotinoid pesticides are justified by the growing weight of scientific evidence they are harmful to bees and other pollinators.

Although scientific evidence has not changed, the government has now allowed restrictions to be eased.
