Review your eating habits. In addition to trying to reduce meat consumption, also avoid wasting food. The loss and waste of food generates 8% to 10% of all greenhouse gas emissions produced by humans, according to a new report on climate change. The Food and Agriculture Organization of the United Nations (FAO) has warned for years about the magnitude of this problem: almost a third of all the food we produce (1.3 billion tonnes per year) is lost or wasted. Also according to the UN, about 38% of the energy resources consumed by the global food system are used to produce lost or wasted food. This is due not only to inefficiencies and limitations in food production and supply systems, but also during consumption. Preventing food loss can contribute to reducing emissions from the agricultural sector, reducing pressure on natural resources and avoiding the need to convert land and expand the agricultural frontier.
