“A Step for Ozone Protection”

There are several examples of human actions causing serious environmental damage. One of these is the ozone layer's depletion. The predicted increase in the amount of UV radiation received at the earth's surface, as well as the impact this would have on human health and the environment, is one of the main causes of public worry about ozone layer depletion.

Ozone layer depletion.

Ozone Layer makes a layer in the atmosphere which acts as a cover to the earth against ultraviolet radiation of the sun. Ozone has the potential to absorb around 97-99% of the harmful ultraviolet radiations coming from the sun that can damage life on earth.

Let’s see the Causes..

  • Chlorofluorocarbons
  • Unregulated Rocket Launches
  • Nitrogenous Compounds
  • Natural Causes

Ozone-Depleting Substances

Sources

Chlorofluorocarbons (CFCs)

Refrigerators, air-conditioners, solvents, dry-cleaning agents, etc.

Halons

Fire-extinguishers

Carbon tetrachloride

Fire extinguishers, solvents

Methyl chloroform

Adhesives, aerosols

Hydro fluorocarbons

fire extinguishers, air-conditioners, solvents

Solution

Looked at ozone levels recorded by the Ozone Monitoring Instrument (OMI) aboard NASA’s Aura satellite and compared them to what the models ‘predicted’ would have happened. What happened in the model was very close to what actually happened in the past, giving the scientists confidence that their model could accurately project what may happen in the future.

One such family of chemical compounds is chlorofluorocarbons (CFCs), whose contribution to depleting ozone in Earth’s upper atmosphere has led to large springtime decreases in ozone around Earth’s Polar Regions, especially over Antarctica, a phenomenon known as the ozone hole that was first reported in 1985. But, as NASA atmospheric scientist Nathaniel Livesey explains, today, thanks to the phase-out of CFCs, Earth’s ozone hole is in recovery. He says the turnaround provides a great example of what humans can do when they work together to solve a global atmospheric problem.

So….We…should…

Do…

  • Avoid Using Ozone Depleting Substances
  • Minimize the Use of Vehicles
  • Use Eco-friendly Cleaning Products
  • Use of Nitrous Oxide should be Prohibited
  • Grow more Trees

Climate changes So should we…

Emblems of earth wish ‘may all sentient beings be at peace, may no one suffer from illness, may all see what is auspicious about our planet’, we all need to step up together to Save our Earth.
