Overall, this shows approval from the U.S government for FGD as an immediate effective solution for dealing with the causes of acid rain. FGD is by no means the only solution for dealing with the causes of acid rain. Many other procedures have shown themselves to be very promising. Because this procedure is still in its experimental stages, it is unlikely to appear in industry until more testing is done. Also, the financial consideration is left to be studied.
Acid rain is caused by natural forces as well as by man and industry.
Although nature's role in creating acid rain has always been present, recent technological advances have added to the process. Luckily, scientists have been able to come up with several solutions to deal with the sources of the acidic compounds in acid rain. FGD, flue-gas desulfurization, has become the leading hope in dealing with emissions release. It is continuously becoming more efficient. Solutions for this serious environmental crisis must be found and introduced as quickly as possible in order to ensure that our environment is relieved of the burden of our waste.
