When we hear that the wars of the 20th century killed 110 million people, or that some 2,000 major disasters that hit the Earth between 2002 and 2006, causing 1.5 million deaths, these numbers do not cause us emotional commensurable with human tragedy depicting quantified. If someone informs us that in 2006 every hour free up 1 million tonnes of carbon into the atmosphere, or about 8 billion tonnes a year, these figures for most of us act like an anesthetic. Wonder, because it is difficult to realize such large sizes. Let's look at what effects can the carbon released in burning fossil fuels. The main effect is to anthropogenic climate change in a few years. On August 1, 2008, the journal «Science», wrote the following surprising: "Data from Greenland's ice show that large climatic changes can happen in just 1 to 3 years." Maybe our climate holds more unpleasant surprises than expected. Around 18% of greenhouse gas emissions due to the enormous scale farming, with key officers cows. These gases are released fertilizer and machinery for the cultivation of grazing, cutting forests to create grazing land, the division of waste and especially the emission of methane from the digestive tract of animals.
