Looking deeply at the way we eat from a global perspective, we can see that meat production is a huge drain on the planet. The United Nations' report Livestock’s Long Shadow, an in-depth assessment of the damaging impact of livestock on our environment, concluded that livestock’s negative effect on our environment is massive and that we need to address it with urgency. The report estimates that raising livestock uses 8 percent of our planet’s water and contributes strongly to water depletion and pollution. Some scientists have estimated that it takes one hundred times as much water to produce a kilogram of beef as it does to produce a kilogram of protein from grain. Part of the reason that so much water is needed to produce livestock is that cattle are fattened on vast amounts of grain, which requires water to grow. In the United States, cattle consume seven times as much grain as the U.S. population as a whole. An Environmental Protection Agency report on U.S. agricultural crop production in 2000 states that, according to the National Corn Growers Association, about 80 percent of all corn grown in the United States is consumed by domestic and overseas livestock, poultry, and fish production. Yet, ironically, more than nine thousand children die each day from causes related to hunger and undernutrition. It is a painful realization that the grain and resources we use to raise livestock could be used more directly instead to feed the starving and malnourished children in the world.
Furthermore, a 2008 report by the Pew Charitable Trust and the Johns Hopkins Bloomberg School of Public Health found that factory farming in the United States is taking a heavy toll on human health and the health of the environment—and that keeping livestock in these “concentrated animal feeding operations” constitutes inhumane treatment. Animal waste pollutes the water and air around the farms, causing illness among farmworkers and farm neighbors, as well as land degradation. Heavy use of antibiotics in factory farming leads to new strains of viruses and bacteria resistant to antibiotics, creating “superbugs” that may pose a public health threat to us all. In the report, the experts recommended phasing out and banning the use of antibiotics in farm animals except for the treatment of disease, instituting tighter regulation of factory farm waste, and phasing out intensive confinement systems.
The devastating environmental and societal impact of raising livestock goes beyond the use of water and land to grow food. Our society’s hunger for meat contributes mightily to the production of climate-changing greenhouse gases. The livestock industry is responsible for 18 percent of the world’s greenhouse gas emissions, a higher share than the entire transportation sector. Seventy percent of forests in the Amazon have been cut to provide grazing land for cattle, and when such forests are destroyed, enormous amounts of carbon dioxide stored in trees are released into the atmosphere. The meat, dairy, and egg industries are also responsible for two-thirds of human-induced emissions of ammonia, which in turn plays a role in acid rain and the acidification of our ecosystem.
The data suggest that one of the best ways to alleviate the stress on our environment is to consume less meat and eat more plant based food, which results in reduction in greenhouse gas emissions. We do not need cattle to process the food for us. It is much better and more efficient for us to eat more plant-based food and process it ourselves. It may seem like a huge change for many people, but reducing the amount of meat and dairy in your diet is a great way to keep your weight in check, improve your overall health, and take steps toward improving the health of our planet. When we learn to eat more vegetables, grains, and beans mindfully, we will enjoy their taste, and we can be happy knowing that we are supporting a new kind of society in which there is enough food for everyone and no one will have to suffer from hunger.
We must take urgent action at the individual and collective levels. For individuals, going towards vegetarianism can have great weight and health benefits. Vegans and vegetarians tend to weigh less than people who consume animal products; they also tend to have lower risk of heart disease, diabetes, and some cancers.
Although this practice is primarily based on the wish to nourish compassion toward animals, it also offers many health benefits. Now we also know that when we eat vegetarian, we protect the earth and help reduce the greenhouse effect that is causing her serious and irreversible damage. Even if you cannot be 100 percent vegetarian, being a part-time vegetarian and consuming a more plant-based diet is already better for your own health as well as the health of our shared planet. You may want to start by eating vegetarian for a few days a month, or you can eat vegetarian only for breakfast and lunch every day. This way, you are already more than half vegetarian. If you feel that you cannot eliminate animal products from your diet for even one meal, simply reducing the portion of meat and eliminating processed meats like bacon, sausages, and ham can lower your risk of colon cancer and your risk of dying an early death from heart disease, cancer, or other causes. This is a good first step to adopting a more plant-based, healthful, environmentally friendly diet.
Using mindfulness to look deeply at what you eat can make it much easier to make such changes, because you realize the benefits they can bring to the planet and yourself—lower weight, lower risk of colon cancer and heart disease, and more energy for doing the things you enjoy. We are “interbeings”: we and our environment are interdependent. And even small changes on our part can have a large impact when combined with others. Our market economy is driven primarily by consumer demand. As a population, if a large number of people make even small moves to eat less meat and more plant-based foods, the livestock industry will shrink. Over time, farmers will find other crops to support their livelihoods. Through such collective awakening we can make a difference in our world.
