Pollution in the fashion industry impact on the environment, the natural crop growing fibers also have been contributing to pollution through the form of agriculture. Cotton production requires a large amount of pesticides and water use. Cotton is considered the world's dirtiest crop because it uses 16% of the world's pesticides. Two of the main ingredients in pesticides are nitrates and phosphates. When the pesticides leak into stream systems surrounding the cropland the nitrates and phosphates contribute to water eutrophication. Water eutrophication is an environmental phenomenon that causes a depletion of oxygen when the nutrient overload from pesticides causes a boom in plant growth and
Marine pollution is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrates or phosphates, stimulate algae growth. Many potentially toxic chemicals adhere to tiny particles which are then taken up by plankton and benthic animals, most of which are either deposit feeders or filter feeders. In this way, the toxins are concentrated upward within ocean food chains. Many particles combine chemically in a manner highly depletive of oxygen, causing estuaries to become anoxic. When pesticides are incorporated into the marine ecosystem, they quickly become absorbed into marine food webs. Once in the food webs, these pesticides can
