What is Ozone Layer?
The ozone layer is a region of Earth’s stratosphere that contains a high concentration of ozone (O3) molecules. It is located about 10 to 30 kilometers above the Earth’s surface. The ozone layer plays a crucial role in protecting life on Earth by absorbing the majority of the sun’s harmful ultraviolet (UV) radiation. UV radiation can cause various adverse effects, including skin cancer, cataracts, and harm to ecosystems.
Montreal Protocol
Montreal Protocol: As you know the ozone layer is part of Earth’s stratosphere and it protects us from the sun’s harmful rays. In the 1970s, scientists made a startling discovery that chemical substances used in air conditioners, refrigerators, and aerosol cans were harming the ozone layer.
In 1985, a huge hole was discovered in the ozone layer over the Antarctica continent. Because of this hole in the ozone layer, alarming levels of ultraviolet (UV) radiation were able to reach the Earth’s surface and cause harm to the Earth’s inhabitants. The UN and its member countries realized that this ozone layer hole had to be dealt with and concrete measures needed to be taken before it was too late.
In this article, we will read about the Montreal Protocol, its achievements, provisions, and impact.
