Human activities like population growth, industrialization, and burning fossil fuels increase carbon dioxide levels and pollution which damage the environment. Acid rain forms from sulphates and nitrates released by burning fossil fuels, acidifying lakes and killing wildlife. Deforestation reduces habitats and biodiversity while pesticides and herbicides have unintended harmful consequences, accumulating in ecosystems. Ozone depletion was directly caused by CFCs from aerosols destroying the ozone layer. Water pollution from oil and gasoline spills contaminates drinking water. The Exxon Valdez spill demonstrated these dangers as global warming increases due to rising greenhouse gases.
