"Dr Rajendra Pachauri, chair of the United Nations Intergovernmental Panel on Climate Change, which last year earned a joint share of the Nobel Peace Prize, has asked consumers to cut their consumption of meat. 'In terms of immediacy of action and the feasibility of bringing about reductions in a short period of time, it clearly is the most attractive opportunity,' said Pachauri. 'Give up meat for one day [a week] initially, and decrease it from there,' said the Indian economist, who is a vegetarian." The Observer, Sunday September 7 2008

Why should we reduce our meat consumption, especially beef? What does eating meat have to do with global warming!?
In 2006, the UN News Center issued a press release as follows:
Rearing cattle produces more greenhouse gases than driving cars, UN report warns
29 November 2006 – Cattle-rearing generates more global warming greenhouse gases, as measured in CO2 equivalent, than transportation, and smarter production methods, including improved animal diets to reduce enteric fermentation and consequent methane emissions, are urgently needed, according to a new United Nations report released today.
“Livestock are one of the most significant contributors to today’s most serious environmental problems,” senior UN Food and Agriculture Organization (FAO) official Henning Steinfeld said. “Urgent action is required to remedy the situation.” . . .
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. It generates 65 per cent of human-related nitrous oxide, which has 296 times the Global Warming Potential (GWP) of CO2. Most of this comes from manure. And it accounts for respectively 37 per cent of all human-induced methane (23 times as warming as CO2), which is largely produced by the digestive system of ruminants, and 64 per cent of ammonia, which contributes significantly to acid rain.
With increased prosperity, people are consuming more meat and dairy products every year, the report notes. Global meat production is projected to more than double from 229 million tonnes in 1999/2001 to 465 million tonnes in 2050, while milk output is set to climb from 580 to 1043 million tonnes.
The global livestock sector is growing faster than any other agricultural sub-sector. It provides livelihoods to about 1.3 billion people and contributes about 40 per cent to global agricultural output. For many poor farmers in developing countries livestock are also a source of renewable energy for draft and an essential source of organic fertilizer for their crops.
Livestock now use 30 per cent of the earth’s entire land surface, mostly permanent pasture but also including 33 per cent of the global arable land used to producing feed for livestock, the report notes. As forests are cleared to create new pastures, it is a major driver of deforestation, especially in Latin America where, for example, some 70 per cent of former forests in the Amazon have been turned over to grazing. . . .
Beyond improving animal diets, proposed remedies to the multiple problems include soil conservation methods together with controlled livestock exclusion from sensitive areas; setting up biogas plant initiatives to recycle manure; improving efficiency of irrigation systems; and introducing full-cost pricing for water together with taxes to discourage large-scale livestock concentration close to cities.
