I've never read such drivel in my life.

Grey Squirrels are a recognised pest regardless of their effect on Red 
Squirrel populations.

They cause untold damage to trees and nesting woodland bird 
populations as well as damage to gardens which are close to woodland 
areas.

Total eradication is unlikely but if people realise the problem 
numbers can be controlled by correctly carried out trapping - believe 
me.
