Something to think about.. an editorial that was recently printed in the New York Times:
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.
This is very true.. I suppose the world needs an extreme situation to convince people to think differently about their actions and how it affects the bigger picture.. When we reach a point where competition for the earth's natural resources between humans and livestock become so fierce.. I'm sure humans won't have any other alternative but to naturally prevent the mass production of livestock for slaughter...
In the meantime.. be thankful for the abundance of steak.. you may find yourselves without such luxury in the future...
