In the developed world, citizens take advantage of the enormous bounty of meat while shopping at markets and dining in restaurants. For some, a meal can only be classified as real if it contains some kind of meat in it. According to the UN, the attitude towards meat consumption has to change, and people must cut back. This is a necessary step in reducing one of the most potent greenhouse gases, nitrous oxide (N2O). A recent study by the UN Intergovernmental Panel on Climate Change (IPCC) suggests that the developed world needs to cut its meat consumption by 50 percent per person by the year 2050.
