Answer:
1. Reduce global warming
Global warming poses one of the most serious threats to the global environment ever faced in human history. Yet by focusing entirely on carbon dioxide emissions, major environmental organizations have failed to account for published data showing that other gases are the main culprits behind the global warming we see today. As a result, they are overlooking the fact that the single most important step an individual can take to reduce global warming [faster than any other means] is to adopt a vegetarian diet.1
In its 2006 report, the United Nations said raising animals for food generates more greenhouse gases than all the cars and trucks in the world combined.2
2. Avoid excessive CO2 production
According to the UN Report, when emissions from land use and land use change are included, the livestock sector accounts for 9 per cent of CO2 deriving from human-related activities, but produces a much larger share of even more harmful greenhouse gases.3
3. Reduce methane/nitrous oxide production
Cows and sheep are responsible for 37% of the total methane (23 times as warming as CO2) generated by human activity.4 With methane emissions causing nearly half of the planet’s human-induced warming, methane reduction must be a priority
The livestock industry generates 64 per cent of ammonia, which contributes significantly to acid rain.5
The livestock industry also generates 65 per cent of human-related nitrous oxide, which has 300 times the Global Warming Potential (GWP) of CO2. Most of this comes from manure.6
In addition to having the advantage of immediately reducing global warming, shifting away from methane-emitting food sources is much easier than cutting carbon dioxide7:
First, greenhouse gas reductions through a vegetarian diet are limitless. In principle, even 100% reduction could be achieved with little negative impact. In contrast, similar cuts in carbon dioxide are impossible without devastating effects on the economy. Even the most ambitious carbon dioxide reduction strategies fall short of cutting emissions by half.
Second, a shift in diet can lower greenhouse gas emissions much more quickly than shifts away from the fossil fuel burning technologies that emit carbon dioxide. The turnover rate for most ruminant farm animals is one or two years, which means that decreases in meat consumption would result in an almost immediate drop in methane emissions. The turnover rate for cars and power plants, on the other hand, can be decades. Even if cheap, zero-emission fuel sources were available today, they would take many years to build and slowly replace the massive infrastructure our economy depends upon today.
Similarly, unlike carbon dioxide which can remain in the air for more than a century, methane cycles out of the atmosphere in just eight years. Therefore, lower methane emissions translate to cooling of the earth quickly.
4. Save large amounts of water
Estimates of the water required to produce a kilo of beef vary, from 13,000 liters8 up to 100,000 liters9 . Whichever figure you use, the damage is plain when you consider that the water required to produce a kilo of wheat is somewhere between 1,000-2,000 litres.
5. Avoid further pollution of our streams/rivers/oceans
Pollution of our waterways is caused by animal waste, antibiotics and hormones entering the water cycle alongside chemicals from tanneries, fertilizers, and the pesticides used to spray feed crops.
Manure, or waste water containing manure, severely harms river and stream ecosystems. Farmed animals produce about 130 times as much excrement as the entire human population of the United States. Since factory farms don't have sewage treatment systems as our cities and towns do, this concentrated slop ends up polluting our water, destroying our topsoil, and contaminating our air.10
Once factory farm pollutants—including nitrogen, phosphorus, antibiotics and pesticides—reach the waterways they cause a great deal of damage to aquatic and human life. Algal blooms are a particular problem, blocking waterways, using up oxygen as they decompose, and killing the natural populations of fish.11
• In large amounts, animal waste can present major problems to the waterways and their surrounding environment. More than 2 billion tons of animal manure was produced worldwide during the late 1990s. Assuming average nitrogen content of around 5%, this makes 100 million tons of nitrogen12 finding its way into our water system.
