What is the common cause of reduction of ozone layer?
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons).
How can we reduce ozone layer damage?
How can we protect the ozone layer?
- Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process.
- Minimize the use of cars.
- Do not use cleaning products that are harmful to the environment and to us.
- Buy local products.
What happens if the ozone layer is decreased?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. UV rays also affect plant growth, reducing agricultural productivity.
Why is the reduction of the ozone layer a problem?
Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.
How ozone hole is formed?
The ozone hole has developed because people have polluted the atmosphere with chemicals containing chlorine and bromine. The primary chemicals involved are chlorofluorocarbons (CFCs for short), halons, and carbon tetrachloride.
Who discovered ozone hole?
In 1985 Jonathan Shanklin was a junior researcher at BAS when he discovered a hole in the invisible shield that protects us from solar radiation. We catch up with him to learn about his work and how it has made a difference. It’s 36 years since scientists first discovered the hole in the ozone layer.
Why is ozone Day on 16th September?
In 1994, the General Assembly proclaimed 16 September as the International Day for the Preservation of the Ozone Layer, commemorating the date in 1987 on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed.
How can we protect and preserve the atmosphere?
Ten Simple Things You Can Do to Help Protect the Earth
- Reduce, reuse, and recycle. Cut down on what you throw away.
- Volunteer. Volunteer for cleanups in your community.
- Educate.
- Conserve water.
- Choose sustainable.
- Shop wisely.
- Use long-lasting light bulbs.
- Plant a tree.
What happens if the ozone hole gets bigger?
as well as famine in humans and wildlife due to lower crop yield and destruction of marine life. So if the hole in the ozone layer gets much bigger — or if the ozone layer depletes entirely — it could cause increased life-threatening problems to human, animal, and plant life.
Where is the so called hole in the ozone layer?
Antarctica
The ozone hole is the region over Antarctica with total ozone of 220 Dobson Units or lower.
Which countries have ozone hole?
The ozone hole over Antarctica is usually more pronounced on the South American side of the frozen continent. Countries that are affected by it the most are Argentina, Chile, South Africa, New Zealand and Australia. The largest ozone hole ever observed in the Antarctic was reported by NASA in September 2000.
