    70% of the world’s fresh water is used for agriculture, mainly for irrigation. The water systems have also been contaminated by fertilizers and pesticides used for growing crops. This leads to eutrophication (massive growth of algae bloom) due to phosphorus and death of aquatic animals. Moreover, agriculture contributes directly to 12-16 % of global greenhouse gases, which leads to rise in global temperatures. Enteric fermentation in livestock (methane)…

  • Birch Tree Research Paper

    gases, such as car emissions and chemicals from factories, affect the quality of the air (Daly, Zannetti 2). This causes damage to all species living in an affected area. Excess nitrogen, which can be created from air pollution, can then cause eutrophication and acidification effects on ecosystems, such as increase in bark pH and the change of ammonium and nitrate in precipitation (APIS). These adjustments mainly affect species that are customized to low nitrogen availability, like lichens…
