The United Nations observes 16 September every year as International Day for the Preservation of the Ozone Layer. The ozone layer is a fragile shield of gas which protects the Earth from the harmful portion of the rays of the sun and thus help in preserving life on the planet. Theme of the day for 2019: 32 Years and Healing. The theme for this year celebrates over three decades of remarkable international cooperation to protect the ozone layer and the climate under the Montreal Protocol. The Montreal Protocol has led to the phase-out of 99 per cent of ozone-depleting chemicals in refrigerators, air-conditioners and many other products.
