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
Plant tolerance to herbivory Using simulated herbivory allows for the control of environmental variables, but replicating natural herbivory is difficult, causing plants to respond differently from imposed and natural herbivory (Tiffin and Inouye 2000). Growing plants in the control environment of the greenhouse may also affect their response as it is still a novel environment to the plants. Even if the plots are grown in natural settings, the methods of excluding or including herbivores, such as using cages or pesticides, may also affect plant tolerance (Tiffin and Inouye 2000). Lastly, models have predicted that manipulated herbivory may actually result in less precise estimates of
