Ozone layer depletion consequences :

Hi friends today we are going to discuss about depletion of the ozone layer.

The key is that the ozone molecule is nothing more than an oxygen molecule that has received an extra oxygen atom through an electrically high voltage. The ozone layer is the most commonly known example, in which ozone is produced by ultraviolet rays (UV) received from the sun. …
Ozone depletion, the release of chemical compounds from gaseous chlorine or bromine-containing industries, or other human activities, gradually depletes the Earth’s ozone layer in the upper atmosphere. Thinning is most common in the polar regions, especially in Antarctica.

What is ozone?

  • O3
  • A gas composed of three atoms of oxygen.
  • Bluish gas that is harmful to breathe.
  • About 90% of the Earth’s ozone is in the stratosphere and is referred to as the ozone layer.
  • Ozone absorb a band of ultraviolet radiation called UVB.

Formation of Ozone Layer

O2+ sunlight =O+O
O+O2=O3

Ozone (O3)
Oxygen molecules are formed when UV collides with the stratosphere. Oxygen molecules merge with oxygen.
O2 = O + O
Atomic oxygen quickly combine with other oxygen molecule to form ozone
O+O2=O3

Ozone depletion

Ozone layer depletion consequences
  • Ozone depletion is the depletion of the ozone layer in the stratosphere.
  • Unlike pollution, which has many types and causes, ozone depletion has been a major human activity.
  • Uses insulating items such as chlorofluorocarbons (CFCs) such as insulating foam, solvents, soaps, air conditioners, refrigerators and take-away containers.
  • Depletion being when CFC’s get into the stratosphere .
  • Ulta violet radiation from the sun breaks up these CFC’s.

The breaking up action releases chlorine atoms.

Atoms of chlorine is react with ozone and start a chemical cycle that destroys the good ozone in that area.
One Cholrine atom can break apart more than 100.000 ozone molecules.

Causes of ozone depletion

Man made causes

  1. Chlorofluorocarbons (CFC’s)
  2. Halons
  3. Methyl Chloroform
  4. Hydrofluorocarbons (HCFCS )
  5. Natural causes

Impacts of Ozone depletion
Harm to human health

  • More skin cancer, sunburns and premature aging of the skin.
  • More characters, blindness and other eye diseases.
  • Adverse impact on Agriculture.
  • UV radiation damages plant growth, especially in plants.
  • Major crop species are primarily vulnerable to increase, UV resulting in reduced growth, photosynthesis and flowring.

Effects on plant

Ozone layer depletion consequences

Physiological and development processes of plans are affected by UVB radiation, even by the amount of UVB in present day sunlight.

Effects on animal

In domestic animals, UV overexposure many cause eye and skin cancers. Marine species (e.g., young fish, prawns, and larvae) have been threatened in recent years by increased UV radiation under the Antarctic ozone.

Effects on material

Wood, plastic, rubber, fabrics and many conversations materials are degrated by UV radiation.
The economic impact of replacing and /or protecting.
material could be significant.

What is the state of the ozone layer?

  • Since the inception of the Montreal Protocol, European consumption (EEA-28 in 1986) has dropped to zero ozone-depleting potential (ODP) in 2002, where it still stands.
  • The depletion of the ozone layer is a profound crisis caused by UV-B radiation reaching the earth’s surface, affecting humans and all living things.
  • This basic chain of ozone depletion has anthropogenic action, and global climate change has occurred in this century.

Importance of ozone layer

  • Ozone is concentrated in the lower stratosphere between 15 and 30 km above the earth surface -the so called Ozen layer.
  • Ozone can be produce by numerous chemical reaction, but the main mechanism in the atmosphere for it’s production and removal in absorption of ultra violet radiat energy from the sun.
  • The maintenance of enough stratosphere Ozen the absorb harmful Ulta violet sunlight is therefore vitally important to all life forms on earth.

Measures to prevent the ozone depletion

Ozone layer depletion consequences
  • Limit private vehicle driving
  • Use eco-friendly household cleaning products
  • Avoid using pesticides
  • Developing stringent regulations for roket lunches
  • Banning the use of dangerous nitrous oxide.

Conclusion and suggestions of ozone layer depletion:

Conclusion:

  • The depletion of the ozone layer is a profound crisis caused by UV-B radiation reaching the earth’s surface, affecting humans and all living things.
  • This basic chain of ozone depletion has anthropogenic action, and global climate change has occurred in this century.
  • This leads to numerous health problems such as heat related problems, skin cancer and other environmental disturbances affecting biological life.
  • Therefore, everyone should be well aware of the harmful effects of ozone depleting agents such as CFCs, plastics, fossil fuels, etc. and reduce and avoid using them.
  • We must all pledge to save nature and keep everyone alive.

Suggestions:

  1. Avoid using refrigerators or air conditioners that run using CFC refrigerants.
  2. Maintain devices using CFCs to prevent leakages.
  3. Avoid aerosol products with CFC.
  4. Avoid fossil fuels and use renewable fuel.
  5. Use solar energy.
