He even gets bonus payments for reducing greenhouse gas emissions.

As the world struggles to reduce pollution causing climate change, attention has focused on the burning of fossil fuels in factories, power stations, and vehicles. scientists says farming and forestry account for more than 30 percent of the greenhouse gases that are gradually heating the earth. Much of that pollution comes from cattle, sheep and pigs that belch or excrete methane, a heattrapping gas more than 20 times as potent as carbon dioxide, the most common global warming gas.

Negotiators from 190 countries have been working to reach a new climate change agreement in December on ways to reduce emissions and help countries adapt to changes in climate. They will reconvene June 1 in Bonn, Germany, for another twoweek session.

Yet it is uncertain whether cutting agricultural emissions will be part of the agreement expected to emerge at the final meetings in Copenhagen, Denmark. The subject is complex, emissions are difficult to measure, and the whole question is politically sensitive, touching on the distrust between the worlds rich and poo online purses r countries.

Scientists say it is too important to be left out.

It would be absolutely nuts to ignore agriculture and forestry in any future climate deal, said Pete Smith, professor of soils and global change at the University of Aberdeen in Scotland. studies say agriculture is the main source of income for one of every three working people. It also is a growing source of pollution, as the global population increases and living standards rise in developing countries where more people are eating meat.

When the FAO report came out in 2006, people in the livestock sector were shocked because they thought they did a good job, says Akke van der Zijpp, a professor of animal husbandry at Wageningen University, a premier Dutch technical facility. Now they are becoming slowly aware that this problem has to be solved.

One way to deal with it is to reduce the methane animals produce by changing their diet or through breeding.

Another is to make use of it and burn it.

Horrevorts says Wageningen Universitys Praktijkcentrum, or Sterksel Research Center, creates 5,000 megawatts a year, enough to power 1,500 homes. The farm uses the electricity it needs and feeds the rest into the national grid, for which the government pays up to euro177 $238 per megawatt as a green energy subsidy.

Pigs can be remarkably housebroken animals. Here, they drop their wa online purses ste through slats on the floor in the middle of the barn while spending most of their time in open stalls to the side. The slurry is channeled into three 4,000 cubic meter 141,250 cubic feet tanks, then mixed into a thick goo with other organic waste like lowquality grain and carrot juice to increase the methane potential. Bacteria break down the material in a digester tank and the gas is siphoned off into a generator to produce electricity.

Horrevorts says a group including his operation and four other commercial farms avoids methane emissions equivalent to 40,000 tons of carbon a year. Dozens of private or nonprofit companies known as offset providers will buy those tons as a way of supporting renewable energy or other projects that reduce carbon emissions, then resell the credits to individuals or companies who want to shrink their carbon footprint.

Last year, Horrevorts said, a British offset provider paid euro5 $6.70 per ton for people wanting to neutralize plane travel or rock concert tickets. This year, the farm was negotiating with a Dutch company seeking to become carbon neutral to promote a green image.

Man finds yet another way to industrialize and reduce the standard of living for one of Gods creatures the pig Isnt it bad enough that these poor creatures are kept in stalls instead of outdoors, allowing them to root and play in the dirt, until their dte of slaughter? While it is commendable that the pig slurry would be converted to gree energy, there is nothing green in the way we keep our farm animals.

Isnt it becoming obvious by the recent swine fl online purses u outbreak that we are setting ourselves up for disease when we keep large quantities of animals in close proximity to humans and each other??? online purses
