New Zealand recently released a proposal to put a price on gases released from agricultural activity.The move is part of an effort to deal with the country's biggest sources of greenhouse gases: sheep and cattle.Greenhouse gases, including carbon dioxide and methane, are believed to cause warming temperatures in the Earth's atmosphere.The measure would make New Zealand the first country to have farmers pay for emissions from farm animals, the Ministry for Environment said.New Zealand, home to 5 million people, has about 10 million cattle and 26 million sheep.These animals release gases such as methane.Nearly half of New Zealand's total greenhouse gas emissions come from agriculture.But agricultural emissions have previously not been part of the country's emissions trading plan.This has lead some to criticize the government's willingness to stop the greenhouse effect, known as global warming.Under an early version of the plan, which was put together by government and farm community representatives, farmers will have to pay for their gas emissions starting in 2025.
