The policies are key to changing things:

By dropping the subsidies on framers which farm livestock, but keeping subsidies on arable farmers.

This will encourage farmers to move to more sustainable products. We have large number of alternatives which available all over Europe.

This will make all the alternatives more competitive. 

All industries that are high polluters should not be subsidies by the public.

This solves climate, animal cruelty, public health issues.

Our climate is very important at the moment and we need policy makers to act now to make a difference. But needs us to direct them.
