b)Reduction of ozone-depleting substances
c)biodiversity conservation
d)control of water pollution

Answer 1

Hint: Montreal protocol was signed in the year 1987 and it was enforced in the year 1989. There were 46 signatories present when the protocol was made. The Montreal Protocol has been ratified by 196 nations including the European Union.

Complete answer:
The Montreal Protocol is also known as the Montreal protocol on a substance that depletes the ozone layer. It is an international protocol that was signed by many countries in order to reduce the ozone layer depletion. This protocol was developed to spread awareness regarding the fast depletion of the ozone layer and the substance used that caused its depletion. In this protocol, the various nations joined together and discussed the various successful ways through which depletion of the ozone layer could be stopped. The use of CFCs was banned due to this protocol as they lead to faster depletion of the ozone layer. Along with CFC, HCFC was also made to reduce in amount. Ozone layer protection has helped in saving the environment and has helped in slowing down global warming.

Additional Information: The biodiversity conservation act of 2002, was enforced by the Indian government. This act was enforced to ensure the safety and conservation of the biodiversity in India. This act was passed to ensure sustainable living and conserving the endangered species of plants and animals. Water act was also passed by the government of India to control the water pollution in the rivers of India. This act was also enforced to restore the dead river bodies and restore the nature of water. It was passed in 1974.
So, the answer is ‘reduction of ozone-depleting substances.

Note: We as individuals can contribute to reducing the depletion of the ozone layer by avoiding CFC and HFC products. We should create awareness among our peers regarding the effects that would be there if the ozone layer depleted.
