Is Meat Sustainable?

M E A T

Now, It’s Not Personal!
But like it or not, meat-eating is becoming a problem for everyone on the planet.

...as environmental science has advanced, it has become apparent that the human appetite for animal flesh is a driving force behind virtually every major category of environmental damage now threatening the human future—deforestation, erosion, fresh water scarcity, air and water pollution, climate change, biodiversity loss, social injustice, the destabilization of communities, and the spread of disease.

How did such a seemingly small matter of individual consumption move so rapidly from the margins of discussion about sustainability to the center? To begin with, per-capita meat consumption has more than doubled in the past half-century, even as global population has continued to increase. As a result, the overall demand for meat has increased five-fold. That, in turn, has put escalating pressure on the availability of water, land, feed, fertilizer, fuel, waste disposal capacity, and most of the other limited resources of the planet.

To provide an overview of just how central a challenge this once marginal issue has become, we decided to survey the relevance of meat-eating to each of the major categories of environmental impact that have conventionally been regarded as critical to the sustainability of civilization. A brief summary observation for each category is accompanied by quotes from a range of prominent observers, some of whom offer suggestions about how this difficult subject—not everyone who likes pork chops or ribs is going to switch to tofu without a fight—can be addressed.

Albert Einstein, who was better known for his physics and math than for his interest in the living world, once said:
“Nothing will benefit human health and increase chances of survival of life on Earth as much as the evolution to a vegetarian diet.” We don’t think he was just talking about nutrition. Notice that in this article we haven’t said much at all about the role of meat in nutrition, even though there’s a lot more to talk about than heart disease. Nor have we gone into the ethics of vegetarianism, or of animal rights. The purpose of those omissions is not to brush off those concerns, but to point out that on ecological and economic grounds alone, meat-eating is now a looming problem for humankind. You don’t have to have any conscience at all to know that the age of heavy meat-eating will soon be over as surely as will the age of oil...
