Consider these numbers. Global livestock grazing and feed production use “30 percent of the land surface of the planet.” Livestock — which consume more food than they yield — also compete directly with humans for water.
When you think about the growth of human population over the last century
or so, it is all too easy to imagine it merely as an increase in the number
of humans. But as we multiply, so do all the things associated with us,
including our livestock. At present, there are about 1.5 billion cattle and
domestic buffalo and about 1.7 billion sheep and goats. With pigs and
poultry, they form a critical part of our enormous biological footprint upon
this planet.
Just how enormous was not really apparent until the publication of a new
report, called “Livestock’s Long Shadow,” by the Food and Agriculture
Organization of the United Nations.
Consider these numbers. Global livestock grazing and feed production use “30
percent of the land surface of the planet.” Livestock — which consume more
food than they yield — also compete directly with humans for water. And the
drive to expand grazing land destroys more biologically sensitive terrain,
rain forests especially, than anything else.
But what is even more striking, and alarming, is that livestock are
responsible for about 18 percent of the global warming effect, more than
transportation’s contribution. The culprits are methane — the natural result
of bovine digestion — and the nitrogen emitted by manure. Deforestation of
grazing land adds to the effect.
There are no easy trade-offs when it comes to global warming — such as
cutting back on cattle to make room for cars. The human passion for meat is
certainly not about to end anytime soon. As “Livestock’s Long Shadow” makes
clear, our health and the health of the planet depend on pushing livestock
production in more sustainable directions.
