What is ozone hole write in 200 words​

Answer 1

Answer:

The ozone story is a remarkable episode in the human history. From the first warnings in 1974 that something might be amiss in the stratosphere because of a particularly inert and useful industrial chemical, through the developments of Montreal Protocol the final steps of CFCs phase out that are still being undertaken, the world has shown that it can respond collectively to a clearly perceived global threat. The scientific community has played a crucial role in this episode, first alerting the world and then plunging into intense research programmes to ascertain the validity of the threat and its remedial actions.

Stopping the rapid decline in ozone layer is as much the responsibility of the civil society as it is of governments and scientists. We can see to it that we limit private vehicle travelling, use eco-friendly cleaning products and avoid chemical pesticides and weedicides.

Ozone layer is the protective shield of the Earth. We have to ensure that the hole in this ‘shield’ doesn’t get bigger, otherwise all life on Earth would perish owing to the wrath of the sun, in the form of UV rays.

Answer 2

Explanation:

Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.[1] The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.
