Why has acid rain become an international problem?

a) increasingly taller chimneys

b)reduced efforts to clean emissions

c) thinner ozone layer

d) pollutants can be trace back to the country of origin

Acid rain become an international problem because it reduced efforts to clean emissions

Further Explanation:

Acid rain includes all types of precipitation with acidic content with a pH value of less than 7. These types of precipitation are harmful to aquatic animals and their infrastructure. Acid rain is the result of the reaction of Sulfur dioxide and Nitrogen oxide with water molecules present in the atmosphere.

Acid deposition is referred to all kinds of precipitation, smog, fog, and mist that have acidic content in it. Deposition can be dry or wet, but in all states, it is hazardous for the environment. The deposition generally has a pH value of less than four and can have pH value as a minimum of 1.5. Sulphuric acid and Nitric acid are two components generally found in the deposition. Pollutants can easily be travel to other countries through the air. Acid pollutants produce in one country deposited as acid rain in other different countries. Acid rain is referred to as an international problem because the emission of pollutants does not equally deposit in that country. Many countries emit a very small amount of pollutants and deposition can be greater. On the other hand, manys countries produce more pollution than is deposit in that country because of general wind directions.
