What are some advantages and disadvantages to the acid rain management techniques?

Answers

Disadvantages of acid rain:
• Acid rain affects the fresh water ponds and lakes and destroys the aquatic life as some species of fishes are rare and may be extinct
• it can affect the trees particularly those that are high altitude
• It can damage historical monuments and buildings
•soil can be affected and can lead to deaths of good microbes

Advantages of acid rain:
• it makes holes in limestone below ground, which creates caves and places to store groundwater, as well as providing habitat for some species
• But the new study shows that sulfuric in acid may have benefits, limiting global warming by counteracting the natural production of methane gases by microbes in wetland areas.

Of course you should do more studying on acid rain but these are the simple ones

Acid rain management techniques include protect plants from acid rain on falling on them.

What is acid rain?

Rain formed when sulfur dioxide and nitrogen oxide react with chemicals in the atmosphere like water,oxygen and carbon dioxide to form sulfuric acid and nitric acid and then falling to ground containing these acids is called acid rain.

Acid rain alters the environment the environment tremendously by damaging plants and aquatic ecosystems.Plants require a specific pH of soil for their optimum growth and nutrition.

Due to acid rain, the acidity of soil increases rendering it unfit for plant growth.Similarly, pH of water also increases which affects the survival of aquatic ecosystems.

It also damages the the monuments made of metals, marbles .Taj Mahal made up of white marble has turned yellowish due to acid rain.
