2.1 What is Acid Rain?
CASE STUDY – THE TAJ MAHAL
The Taj Mahal in Agra, India’s most popular tourist attraction, has been a source of concern for the past two decades. Pollutants such as sulphur dioxide and nitrogen dioxide have been produced by factories in and around Agra, such as rubber manufacturing, cars, chemicals, and, in particular, the Mathura oil refinery. Sulphuric acid and nitric acid are formed when these gases react with water vapour in the atmosphere. Rain brings the acids down with it, rendering the rain acidic. This is referred to as acid rain. The monument’s marble is eroded by acid rain. The condition is also known as “Marble cancer.” The marble has yellowed due to suspended particulate matter, such as soot particles released by the Mathura oil refinery. The Supreme Court has taken several steps to save the Taj.

Water shortages may be caused by climate change, such as altered weather patterns, including droughts or floods, increased pollution, and increased human demand and water overuse.
Due to overpopulation, many countries in the world face the severe problem of water shortage. Several large cities of India have experienced water shortages in recent years.
Let’s look at some essential pictures which show how badly water shortages hit India
Water scarcity is driven by two converging phenomena: growing freshwater use and depletion of usable freshwater resources.
The problem of water scarcity is rapidly rising in the current scenario, and it becomes the most significant challenge because the ratio of safe drinking water is reducing.
Wasteful use of water for Agriculture and Industries
Have you ever paid attention to the water getting wasted at the house? Let us list out few such activities.
Using a hose to wash the car can use up gallons of water. If you leave the hose running, you can end up wasting almost 150 gallons of water.
Did you know that taking long showers wastes five to 10 gallons of water? Use buckets and a pail for bathing wisely.
The kitchen uses a lot of water, and there are plenty of ways in which one may unknowingly waste it. Washing fruits and vegetables in running water will not get them any cleaner than washing them in a pan filled with water.
Cleaning the house is a whole task, and much water is wasted if not done wisely.
