We the undersign acknowledge the fact that grey squirrels came to the U.K. after the red squirrels, but does that still means it is right to kill off the grey squirrels? We believe that both squirrels can survive. If you are worried about lack of food for the red squirrels, consider given them more food instead of trying to wipe out the greys. Humans should not interfere with the lives of the squirrels. Or, if it seems necessary, we should try to find a more humane way of decreasing the grey squirrel population.
