The International Day of the Preservation of the ozone layer commemorates the day the Montreal Protocol on Substances that deplete the ozone layer was signed and adopted by the United Nations.
Dated back to 1987, this is a vital historic day when a global collective decision was made to protect the ozone layer. Every September 16th, we are reminded of our fundamental duty to protect the ozone layer not just for us, but for future generations to come.
This year's focus is to call our attention to the overriding importance of the ozone layer, and how we can work together to heal the ozone layer from the damage it has suffered in its current state.
The depletion of the ozone layer and climate change are interrelated in several ways. Hence, we need to examine these in detail.
Let's dive right in!
What is the Ozone Layer?
The Ozone Layer is an atmospheric shield that blocks harmful Ultraviolet (UV) rays from the sun, preventing them from reaching the earth's surface.
This protection is vital because Ultraviolet Radiation has critical damaging effects when it penetrates. It affects both wildlife and humans and even hinders the normal growth of green plants.
The Ozone Layer is the protective shield against these effects. Unfortunately, the ozone layer has been depleted due to the increased concentrations of ozone-depleting chemicals. (Stated in the Montreal Protocol)
What has caused Increased concentrations of Ozone Depleting Substances (ODS)?
The increased concentrations of ozone-dreaded chemicals have been detected to be from human activity. Some ODS that cause atmospheric pollution include:
- Chlorofluorocarbons (CFCs) are reported to be the major cause of ozone depletion. This ODS is usually found in dry cleaning agents, foam products and sterilisers.
- Hydrofluorocarbon (HCFCs) are released from products in which they are used as cooling agents or insulation materials. Although not in high concentration like CFCs, HCFCs effects are found to cause skin irritations, and adversely affect fertility.
- Halons - Halons-1211 and 1301 are mostly emitted from selected fire extinguishers.
- Methyl Chloroform - widely used in industries for cold cleaning, chemical processing and adhesives
The impact of ozone depletion induced by human activities has posed a serious threat to stable climate conditions. Climate changes are affecting Human health, food, water security and the effective functioning of ecosystems.
These effects have been greatly mitigated by the Montreal Protocol through the limits and restrictions placed on the production and release of ozone-dreaded chemicals. However, we all have a part to play.
Now, here comes your part in this Ozone Layer Protection Duty of ours.
1. Use only Ozone-friendly products. For example, using cleaning products that are made of natural substances.
2. Active ODS chemicals are produced in most cars. Healthy ways to reduce the production of ODS include: walking/biking to short distances, carpooling, or using public transport.
3. Maintain your air-conditioner and refrigerator regularly to avoid the release of CFCs into the atmosphere.
4. Check for active ODS ingredients in every product.
5. Be an Advocate
The environment is not just ours to use, it is a gift that must be preserved for future generations to come.
Let's all play our part.
Happy World Ozone Day!
