Question

The Ozone Day is observed every year on September 16 as on this day in 1987 the ____ was signed for launching efforts to arrest the depletion of the fragile ozone layer in the stratosphere the prevents the harmful UV rays of the sun from reaching earth. Fill in the blank
A. Montreal Protocol
B. Geneva Protocol
C. Kyoto Protocol
D. Nagoya Protocol

Answer 1

Hint: A protective barrier of gas, the ozone layer, protects the Earth from the harmful portion of the sun's rays, thereby helping to sustain life on the planet. The main aim of the day is to raise awareness of the loss of the ozone layer and to look for ways to protect it.

Step by step answer:An international treaty intended to protect the ozone layer by phasing out the development of various substances responsible for ozone depletion is the Montreal Protocol on substances that deplete the ozone layer often referred to simply as the Montreal Protocol. The Montreal Protocol, signed on 26 August 1987, came into effect on 26 August 1989.
-The Convention prohibiting the use of asphyxiating, toxic or other gases and bacteriological methods of warfare in warfare, generally referred to as the Geneva Protocol, is a treaty restricting the use of chemical and biological weapons in foreign armed conflicts.
-The Kyoto Protocol incorporates the United Nations Framework Convention on Climate Change by committing to restricting and reducing greenhouse gas ( GHG ) emissions by developed countries and economies in transition, in line with negotiated individual goals.
-The purpose of the Nagoya Protocol, adopted in Nagoya on 29 October 2010, is to achieve one of the three objectives of the Convention on Biological Diversity: the equal and equitable distribution of benefits resulting from the use of genetic resources, thus contributing to the protection and sustainable use of biodiversity.
Hence option A is correct.

Note: Ozone depletion is a significant environmental issue because it increases the amount of UV radiation reaching the surface of the Earth, increasing the rate of damage to skin cancer, eye cataracts, and the genetic and immune system. Produced chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), are the main cause of ozone depletion and the ozone hole.
