Lichens are bio indicators of air pollution. They are highly sensitive to sulphur dioxide (SO2) pollution in air from automobiles and other factories. Delhi has maximum air pollution due to a large number of vehicles compared to Manali and Darjeeling. Therefore, the growth of lichens does not occur in Delhi or any place, where air pollution is high.

But the first approach by the government was traced to National Forest Policy, 1894, which was revised in 1952. The policy focuses on the extension of forest and start a green movement in the country.
This policy states that 33% of the geographical area should be covered by forest/tree.
The 2019 survey has found an increase of 5,188 sq km in total forest and tree cover in the country.
Tree and forest cover together made up 24.56% (8,07,276 sq km) of India’s area. In the last assessment it was 24.39%.

(B) Automobiles
(C) Refrigeration and Air Condition
(D) Fertilizers
Answer: C
Explanation:
Chlorofluorocarbons (CFC’s) are chemical compounds made up of chlorine, fluorine and carbon. They are harmful when released into the atmosphere because of their destructive reaction with ozone. Sources of CFC’s are spray can propellants (aerosols) , cleaning solvents, refrigerants, air conditioning (“freon” gas), etc.
Most chlorofluorocarbons are released into the atmosphere through leakages from refrigerants and the use of aerosols.
