Animal Aid

Grey squirrels are killed using a variety of barbaric but legal methods, including being clubbed to death and poisoned with warfarin, which causes the animals to bleed to death over several days.

Red squirrel numbers can be boosted in a number of ways without harming the grey squirrel, including establishing them on islands, changing tree planting patterns and offering supplementary feeding.

But, as habitats and the climate continue to change, we may soon be faced with a bigger question: is it justifiable, or even practical, to try to force certain species to live in a landscape that can no longer support them? And, as new species move in and thrive, should they be eradicated, simply because they did not originate there?
