10 Reasons Why the Meat and Dairy Industry Is Unsustainable

Editor’s note: This Care2 favorite was originally posted on December 31, 2013.

Like it or not, you can’t hide from the fact that eating animal products creates a massive problem for everyone on the planet.

Here are 10 reasons why the meat and dairy industry is unsustainable:

1. Deforestation

Farm animals require considerably more land than crops to produce a given amount of food energy. In Central America alone, 40 percent of all rainforests have been cleared in the last 40 years for cattle pasture to feed the export market — often for U.S. beef burgers. The World Hunger Program calculated that recent world harvests — if distributed equitably and fed directly to humans, as opposed to livestock — could provide a vegan diet to 6 billion people.

2. Freshwater

Without a doubt, animal agriculture has one of the largest water footprints on the planet. It may be hard to believe, but the standard American diet requires a whopping 4,200 gallons of water per day – including animals’ drinking water, irrigation of crops, processing, washing, etc. — whereas a vegan diet only requires 300. The easiest way to reduce demand for water is to eliminate the consumption of animal products.

3. Waste disposal

Today’s factory farms house hundreds of thousands of cows, pigs and chickens — and, in turn, produce astronomical amounts of waste. In the U.S., these giant livestock farms generate more than 130 times the amount of waste that humans do. Agricultural waste has polluted thousand of miles of rivers and contaminated groundwater, killing aquatic life and creating huge dead zones.

4. Energy consumption

For that steak to end up on your plate, the cow has to consume massive amounts of energy along the way. Growing grain — often with a heavy use of agricultural chemicals — to feed cattle, transporting cattle thousands of miles to slaughter and market and refrigerating and cooking the meat all amounts to an absurd use of resources. On average, it takes 28 calories of fossil fuel to produce 1 calorie of protein from meat, whereas it takes only 3.3 calories of fossil fuel to produce 1 calorie of protein from grain.

5. Food productivity

The food productivity of farmland is quickly falling behind population growth, and the only option available to us — short of stabilizing the population — is to cut back on meat consumption and convert grazing land to food crops. In the U.S., an estimated 56 million acres of land are dedicated to hay production for livestock. Only 4 million acres are used to grow vegetables for human consumption.

6. Global warming

Global warming is driven by energy consumption, and as noted above, livestock are energy-guzzling. But that’s not all. Livestock also emit potent global warming gases into the environment. Cattle, in particular, produce a significant amount of methane. For example, a single dairy cow produces an average of 75 kilos of methane annually.

7. Loss of biodiversity

Poaching and the black market sale of bushmeat is becoming a growing problem as our planet becomes increasingly overcrowded. Poorer populations often venture into wildlife reserves to kill everything from elephants and chimpanzees to bonobos and birds. Hunters rely on logging roads maintained by big multinational companies for easy access to the forest — and the animals that inhabit it.

8. Grassland destruction

As the herds of domesticated animals expanded, bison and antelope habitat was replaced by monoculture grasslands for large scale cattle grazing. Grasslands have suffered a massive loss of biodiversity as a result. What was once a rich ecosystem is now is a single species monoculture.

9. Soil erosion

With 60 percent of the United States’ pastureland overgrazed, the acceleration of soil erosion and degradation is an increasing concern. It takes approximately 500 years to replace just 1 inch of precious topsoil. While fertilizers may be able to replace a small amount of lost nutrients, the large inputs of fossil energy required is completely unrealistic and unsustainable.

10. Lifestyle disease

The excessive consumption of meat and dairy in developed countries combined with environmental pollution and lack of exercise is causing an abundance of preventable health problems, such as heart disease. While Western nations struggle with strokes, cancer, diabetes and heart attacks, other countries are impacted from disease brought on by a lack of access to agricultural land.

When taking into consideration all of the points made above, it’s clear that a meat and dairy dependent diet is unsustainable in the long term. Couple that with the threat of rapid population growth — the current U.S. population is an estimated 285 million and is projected to double in the next 70 years — and even greater stress will be placed an our already limited resources.

Regardless of the role of meat and dairy in nutrition or the ethics of animal rights, on the grounds of economic and ecological sustainability alone, the consumption of animal products is a looming problem for humankind.

If you want to live a low impact lifestyle and reduce your use of the world’s precious resources, try opting for animal-free food choices instead.

Also, I'm sick of racist meat eaters always criticizing Asian dining choices while they themselves chow down on animals they consider "appropriate" for eating. It's no more horrifying or despicable to eat a dog or cat than it is to eat a cow, pig, lamb or chicken. EATING MEAT IS EITHER CRUEL OR IT IS NOT

@ Chrissie R Grazing land is productive to the animals who would naturally graze there. Unfortunately, in the united states, these natural grazers are seen as nuisances to the cattle industry and the bureau of land management who leases PUBLIC land to the cattle industry for pennies sides with that industry when it comes to who gets to graze the land. This does not bode well for the natural grazers and it is a death sentence to biodiversity. Cattle ranchers should only be allowed to graze their cattle on their land. They should only be able to feed the cattle plants grown on their land. The cattle industry along with the other "feed animal" (your grotesque words) industries are heavily subsidized by the government. That should stop. Along with industry employees such as yourself who troll articles such as this trying desperately to keep the proverbial wool pulled over the eyes of unsuspecting consumers. US citizens should have to pay the true price of meat, dairy and eggs if they choose to consume them. Only then will the playing field be leveled. Fruits and vegetables would be on the dollar menu. There would be more diversity of crops grown. Soil would become healthy again. The standard american diet would no longer be SAD. Humans would become healthy again. Animals would not be needlessly slaughtered. Methane would not be released into the atmosphere by all those extra animals warming an already dangerously warm planet. You are trying desperately to prop up a dy

Idealistic. Yet, we must continue to aim for our highest actions. Btw, the food industry also is destroying vegetation with toxic substances, so, we can't depend upon plant life to save us. We have many issues to resolve, and many problems to overcome. This is not simple. However, it is simply necessary. For survival of all life. Earth will abide even is all of its creation becomes extinct. It will rebirth new species. Until Earth too falls away. Nothing is permanent. Love is the force of life, and continues, beyond all our dilemmas.
