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 to plant communication via mycorrhizal networks have also initiated nutrient transfer by causing the movement of carbon from the roots of the stressed plant to the roots of a conspecific plant over a mycorrhizal network. Thus, nutrients transferred through mychorrhizal networks act as signals and cues to change the behavior of the connected plants. It is hypothesized that fitness is improved by the transfer of infochemicals through common mycorrhizal networks, as these signals and cues can induce responses which can help the receiver survive in its environment. Plants and fungus have evolved heritable genetic traits which influence their interactions with each other, and experiments, such as
