Almeria, The impact of global warming will be more so if people do not immediately limit air pollution, mainly from industry and transport. For to eat alone, each man has contributed pollution as much as 2 tons of carbon dioxide (CO2) per year.
That figure already includes the various stages of preparation of food, ranging from cultivation, processing, packaging to distribution and sales. Of the total emissions produced by humans each year, the stages that pollution contributes about 20 percent.
Experts from the Universidad de Almeria (UAL) that conclusion after examining the influence of food consumption patterns in Spain with the level of environmental pollution. These conclusions were published in international journals Life Cycle Assessment.
“Within a year, each person produces 2 tons of carbon dioxide pollution from food and energy spent about 20 gigajoule to process it,” said Ivan Munoz, one of the researchers as quoted by Science Daily, Wednesday (11/03/2010).
Emissions of carbon dioxide is the most widely produced from the farm, such as meat and milk processing. Agriculture, fisheries and food processing industry also includes the major sources of environmental pollution.
In addition to polluting the air, also contaminate food processing waste waters, especially with nitrogen and phosphorus. Even the natural waste of human waste is also a source of water pollution.
In the water, the organic matter in human excreta into a source of nutrients for the algae. The result is a boom or the explosive growth of algae that make depleted dissolved oxygen levels and smells.
Fortunately, human waste into fertilizer for plants are also others that reproduce the occurrence of photosynthesis. One of the products of photosynthesis is oxygen more or less able to neutralize carbon dioxide emissions from food.
