How Does Air Pollution Effect the Environment?
Pollutants in the air, deposited on soils or surface waters, can have a variety of environmental impacts. Like humans, animals and plants can experience health problems if they are exposed to sufficient concentrations of air pollution over time. Effects on Vegetation Acid rain does not usually kill trees directly. Instead, it is more likely to weaken trees by damaging their leaves, thereby limiting the nutrients available to them. This loss of nutrients in their foliage makes trees more susceptible to damage by other environmental factors, particularly cold winter weather. Acid rain can harm other plants in the same way it harms trees. Farmers frequently add fertilizers to the soil to replace nutrients to lessen the effects of acid rain. The experiments in this lesson will visually demonstrate a significant change in pH levels. This is done purposely to demonstrate the possibilities of pH level change caused by acid rain. It would be beneficial to explain to students that there are nat
