Meat pollute and emit CH4. Much better food veg

As can be seen in the fourth column, the flatulence of farm animals, produces an enormous amount of CH4 gas methane, a greenhouse gas 23 times more of the same harmful CO2 carbon dioxide (Ogino et al. 2007, cited).

Eating a vegetarian, as well as their health is good health for others and the environment. And yes, for cereals, pulses, oilseeds, vegetables and fruits, which are the vast majority of eating vegetarian, to be products require much less energy (and therefore cause much less expense) and pollution of the meat.
The production of 1 kilogram of meat causes major environmental pollution: more or less than that produced by a car that runs for 250 km or a light bulb for nearly 20 days . And 'one of the data found in a study by Akifumi Ogino of the National Institute of Livestock and Grassland Science in Tsukuba, Japan, the scientific journal Animal Science Journal (original article) .
The researcher, and colleagues, assessed the effects of beef production on global warming, increasing acidity and eutrophication of water (see also the laity through the proliferation of algae and plants) , and the consumption of energy.
Scholars have analyzed the calf production, focusing on animal management, the effects of production and means of transport used for the ditribution. Combining the information gleaned from these observations with those that emerged from previous studies on the impact of animal feeding systems, were able to calculate the "weight" that the environment is forced to pay for the production of each portion of beef.
The study showed that the production of 1 kg of meat the emission of gases that cause global warming, with a potenzionale global warming equivalent to 36.4 kilograms of carbon dioxide.
Meat production also requires the issuance of fertilizer equivalent to 340 grams of sulfur dioxide and 59 grams of phosphate, and consumes around 169 megajoules of energy. In summary, the equivalent of carbon dioxide CO2 emitted by average European car that travels 250 km, and with a consumption energy equal to that necessary to keep lit a 100 watt bulb for nearly 20 days.
But not even all. In fact, calculations based on standard industrial methods of meat production in Japan, did not take into account the ecological impact of the entire infrastructure of the farms, the cost of transporting it. This means that the "environmental cost" of the steak could be even higher than shown.
Finally, a curiosity. Most of the emissions of greenhouse gases are produced in the form of methane CH4 - a greenhouse gas many times more polluting than carbon dioxide CO2 - issued by the digestive systems of animals. A cow can emit every day in the form of flatulence up to 500 liters of CH4, as reported by one of the many sites that he was involved in this unusual theme. And the garlic added to the feed has reduced by about 50% of methane emissions, being a well-known regulation of intestinal bacteria. This can be useful to humans. In addition, there is pollution from manure, for which cattle are abundant.

Agriculture is Responsible for an estimated 14 percent of the world's greenhouse gases. A Significant Portion Of These Emissions from methane as, Which, in terms of the ITS contribution to global warming , is 23 times more powerful than carbon dioxide. The U.S. Food and Agriculture Organization says that agricultural methane output could increase by 60 percent by 2030 [Source: Times Online ].
The world's 1.5 billion cows and billions of other grazing animals emit dozens of polluting gases, including lots of methane. Two-thirds of all ammonia comes from cows. The large amounts of methane produced by cows are now a cause of concern and the subject of much scientific research. Cows emit a massive amount of methane through belching, with a lesser amount through
flatulence . Statistics vary regarding how much methane the average dairy cow expels. Some experts say 100 liters to 200 liters a day (or about 26 gallons to about 53 gallons), while others say it's up to 500 liters (about 132 gallons) a day. In Any case, that's a lot of methane, an amount comparable to the pollution produced by a car in a day.
.
Then there's the sad note of the various waste of cereals and grains as feed. More than two thirds of the energy used in the production and transport of food for animals.
To improve the situation, the researchers suggested improving waste management emrgono during the production cycle and reduce by one-month intervals mating of animals. Better management could lead to a decrease of almost 6 percent of the environmental cost.
What to do? The solution would be obvious, easy and economical to become vegetarians. Instead, a Swedish study in 2003 suggested the meat "organic." The animals bred in freedom rather than locked up in chains of production, caused 40 per cent less emissions of greenhouse gases and consumes 85 percent less energy. "Emissions of methane produced from the herd of cattle are declining, with the latest innovations in feeding," says Karen Batra of the National Cattlemen's Beef Association in Centennial (Colorado, USA).
"Everyone is trying to find ways of reducing the causes of pollution," said Su Taylor of the Vegetarian Society in England, "but the only truly effective solution is to stop eating meat."
