The correct answer is A. Increased use of pesticide.
The name 'green revolution' is very misleading, because it makes you believe that is something positive about the nature. In fact, it is something that made a lot of harm to the environment with pollution and increased erosion caused by the usage of chemical fertilizers and pesticides and herbicides, caused problems in the societies because a lot of crops needed for people to feed themselves where destroyed so that other plants can be produced.
Answer:
The ozone layer is usually referred to as a blanket that protects the earth from the harmful incoming solar radiation. It is located in the Stratosphere layer but also there is another ozone layer in the troposphere, commonly known as the troposphere ozone.
The stratospheric ozone is considered to be good ozone because it is located at a high altitude and it directly acts as a shield protecting the earth from the solar radiation, which can cause various types of skin diseases and also can increase the surface temperature of the earth.
On the other hand, the troposphere ozone is considered to be bad as it is located near to the ground surface and is mainly comprised of the greenhouse gases, that are harmful to the atmosphere and also increases the surface temperature of the earth.
CFC is one of the greenhouse gases that are harmful to the atmosphere because CFC molecules are continuously hit by the solar radiations that breaks the bond between the carbon and chlorine, resulting in the production of a single Chlorine atom, which eventually breaks down down the ozone layer by reacting with it. This is how the CFCs depletes the stratospheric ozone.
The depletion of the ozone layer leads to the global climatic changing, affecting all the biotic and abiotic components of the earth. This is a long term effect. This global warming is a threat to destroy the earth, so preventive measures must be taken in order to reduce the causes and use of those substances that can lead to catastrophic changes.
