5 But what are the causes of the increase in emissions? ü The burning of carbon, oil and gas produces carbon dioxide and nitrogen oxide. ü Deforestation. Forests are known to be the lungs of the world and help regulate the climate by absorbing CO2 from the atmosphere. By cutting down trees, this action is lost and the CO2 stored in the trees is released into the atmosphere, thus fuelling the greenhouse effect. ü Intensive livestock farming is among the factors affecting global warming (there are more than 1 billion cattle raised worldwide). Thirty-two percent of emissions of this potent greenhouse gas from human activities are related to livestock farming, and come mainly from cattle digestion (as well as excrement, from pigs and cattle). ü Nitrogen fertilizers in fact, produce nitrogen oxide emissions as well as lead to 'soil acidification and loss of biodiversity. ü Fluorinated gases are emitted by equipment and products that use such gases. These emissions cause a powerful greenhouse effect, up to 23,000 times stronger than that caused by CO2.
