The dorper, however, has been purpose bred to grow and fatten on grass, no large inputs of energy, and by eating grass on land where no other food will grow, stimulates carbon uptake, preventing grass from becoming tall and rank,so it grows and takes up more CO2.
So few, realise that all living things rely on the simple equation of life
ie CO2 + Sunlight = plant matter ( fossilised as coal and oil)
plant matter + fire = CO2 + heat (original sun's energy)
plant matter + animal = energy for growth & movement + CO2
