Clean Air Act and acid rain improvement
Acid rain is currently one of the most concerning environmental problems
today, due to both its ecological effects and impacts on human health.
Although measures have been taken to reduce nitrogen oxide and sulfur
dioxide emissions, years of power plants releasing these chemicals have
left permanent damage to our forests and aquatic environments. However,
improvements
have been measured in the US since the enactment of the 1990 Clean Air
Act. With the transient nature of acid precipitation, lets hope that
this improvement will spread to other parts of the world.

Acid rain can cause not only a lower pH in aquatic environments, but also higher aluminum concentrations. If the pH is less than 5, most fish eggs won't hatch; this problem is compounded when we consider the amount of insect, fish, and countless other organismal biodiversity lost in the process. I'm so glad the Clean Air Act was put into affect!! I cannot imagine life without the countless and unique animal species that inhabit this planet!
