Cow 'emissions' more damaging than cars

Cow 'emissions' more damaging to planet than CO2 from cars

A United Nations report has identified the world's rapidly growing herds of cattle as the greatest threat to the climate, forests and wildlife. And they are blamed for a host of other environmental crimes, from acid rain to the introduction of alien species, from producing deserts to creating dead zones in the oceans, from poisoning rivers and drinking water to destroying coral reefs.

The 400-page report by the Food and Agricultural Organisation, entitled Livestock's Long Shadow, also surveys the damage done by sheep, chickens, pigs and goats. But in almost every case, the world's 1.5 billion cattle are most to blame. Livestock are responsible for 18 per cent of the greenhouse gases that cause global warming, more than cars, planes and all other forms of transport put together.

Burning fuel to produce fertiliser to grow feed, to produce meat and to transport it - and clearing vegetation for grazing - produces 9 per cent of all emissions of carbon dioxide, the most common greenhouse gas. And their wind and manure emit more than one third of emissions of another, methane, which warms the world 20 times faster than carbon dioxide.

Livestock also produces more than 100 other polluting gases, including more than two-thirds of the world's emissions of ammonia, one of the main causes of acid rain.

Ranching, the report adds, is "the major driver of deforestation" worldwide, and overgrazing is turning a fifth of all pastures and ranges into desert.Cows also soak up vast amounts of water: it takes a staggering 990 litres of water to produce one litre of milk.

Wastes from feedlots and fertilisers used to grow their feed overnourish water, causing weeds to choke all other life. And the pesticides, antibiotics and hormones used to treat them get into drinking water and endanger human health.

The pollution washes down to the sea, killing coral reefs and creating "dead zones" devoid of life. One is up to 21,000sqkm, in the Gulf of Mexico, where much of the waste from US beef production is carried down the Mississippi.

The report concludes that, unless drastic changes are made, the massive damage done by livestock will more than double by 2050, as demand for meat increases.

I blame stupid hippies for not eating enough meat

the damn cows....


THE HEGELIAN PRINCIPLE:

Step one: CREATE A "PROBLEM": Create it or take one that does exist and build it up out of all proportion to its real importance;

Step Two: PUBLICISE THE "PROBLEM": Make sure a story about this problem appears in the news media each and every day, in newspapers, news magazines, radio, and television. Hit it again and again in a "steady drumbeat" that soon has people who don't pay real attention to politics (which is the majority of them) clamoring for a "solution" to the problem;

Step Three: OFFER A "SOLUTION": A solution that takes away one or more of our rights and further undermines the constitutional protections we all are supposed to enjoy. One that involves higher taxes (to pay for this "solution," of course), and one we would not have allowed them to do without this previous conditioning of the public.

AT LAST, evidence that global warming is a load of hot air. Cow flatulence has attracted the attention of ministers after emerging as an environmental menace to rival factory chimneys, Chelsea tractors and cheap air travel.

Bovine emissions account for around one million tonnes of methane a year in the UK and now the government wants farmers to change what they feed the animals to cut down greenhouse gases.

Scientists have already conducted experiments on different cattle feed to determine which one best cuts down gaseous after-effects, and ministers have not ruled out action to force farmers to change their cows' diet.

Officials have worked out that agriculture contributes 7% of all the UK's greenhouse gas emissions. The sector accounts for 36% of Britain's emissions of methane, and farm animals - chiefly cows - contribute the vast majority of it.

The problem is worse in Scotland, which has a higher concentration of agriculture, meaning farm animals produce 46% of methane emissions.

Methane has been described by the United Nations as 23 times more "warming" than carbon dioxide. A UN report reveals that: "Livestock are one of the most significant contributors to today's most serious environmental problems."

The answer, according to scientists at the Department for Environment, Food and Rural Affairs (Defra), is for farmers to alter what they are piling into their cows' front ends.

A Defra spokeswoman said:

"We do encourage farmers to look at this research and consider acting on it. There is no regulation [saying] they will have to change fodder, although that may be something we will have to look into in the future."

Britain's attempts to get to grips with the issue are in line with a growing trend in research into cows' digestive systems around the world. Scientists at the Rowett Research Institute in Aberdeen have recorded impressive reductions by introducing a mixture of organic sugars and a special bacterium into the animals' diet.

Belgian researchers have found that adding fish oil to fodder reduced methane emissions in cattle by up to 80%, while the Australians are even experimenting with a flatulence-reducing vaccine.

And the UK, too, is finally falling into line. In a parliamentary answer politely entitled "Bovine Emissions" last week, farming minister Ian Pearson said "recent research suggests that substantial methane reductions could be achieved by changes to feed regimes".

it doesn't exist. just another assumption by the scientific community. thirty years ago they said we were going into another ice age.

Cow farts don't exist?

the cows told me they prefer the term "flatulence"
