🛡️What is the Ozone Layer?
The ozone layer is a thin shield of gas in the Earth’s stratosphere that absorbs most of the Sun’s harmful ultraviolet (UV) radiation. Without it, life on Earth would be exposed to dangerous levels of UV rays, leading to health and environmental risks.
⚠️Reasons for Ozone Layer Pollution
The main cause of ozone depletion is the release of chemicals such as chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances. These are commonly found in old refrigerators, air conditioners, aerosol sprays, and industrial solvents. When these chemicals reach the upper atmosphere, they break down ozone molecules, creating holes in the layer.
📅Why the Day is Celebrated
The International Day for the Preservation of the Ozone Layer is observed every year on September 16. It marks the signing of the Montreal Protocol in 1987, an international agreement to phase out the production of harmful chemicals and protect the ozone layer.
🌞Effects of Ozone Depletion
A weakened ozone layer increases exposure to UV radiation, which can cause skin cancer, cataracts, and other health issues in humans. It also affects ecosystems, damaging crops, reducing fish populations, and harming wildlife.
🌱Global Efforts to Protect the Ozone Layer
The Montreal Protocol is one of the most successful environmental agreements, resulting in a major reduction of ozone-depleting substances. Many countries have transitioned to safer alternatives and continue working toward full recovery of the ozone layer.
🤝A Shared Responsibility
This day reminds us that protecting the ozone layer requires global cooperation and individual responsibility. By supporting eco-friendly products and reducing harmful emissions, we can contribute to a safer and healthier planet.
