We understand from the passage that cattle that feed on grass ----.
By 2020, total meat consumption in developing
countries is predicted to have more than doubled.
Yet livestock, especially in wealthy countries, already
munches its way through 36 per cent of the world's
grain harvest. All that grain exacts a heavy
environmental cost, because the increased demand
pulls farmers towards growing maize and soybean
and away from pasture and fodder crops such as
alfalfa that do so much for soil health. And grain-fed
animals tend to be housed in huge feedlots, where
crowding causes disease and veterinary surgeons
use more antibiotics, and where vast mountains of
manure pollute the surroundings. Consumers could
reverse many of these problems by demanding meat
from grass-fed livestock, or simply by eating less
meat. And as an added bonus for overfed
Westerners, the meat from grass-fed cattle is leaner
than that from grain-fed animals.
