🌍 The ozone layer, a protective belt around the Earth, was being threatened in the 80s.
⚠️ Scientists warned that the ozone layer could be completely destroyed by 2050.
🌱 In an unprecedented act, the world took action to prevent the destruction of the ozone layer.
🌍 The ozone layer is a powerful shield against ultraviolet radiation from the Sun.
❗ In 1985, scientists discovered a massive loss of ozone over Antarctica, forming a 'hole'.
🔬 Dr. Susan Solomon and her team investigated the cause of the ozone hole and took measurements to understand why it was getting worse.
🌍 The main problem with the ozone layer was chlorine from man-made compounds called CFCs.
☀️ CFCs break down into chlorine when exposed to the sun in the stratosphere and destroy ozone molecules.
⏱️ The long lifespan of CFCs in the atmosphere leads to a buildup and exponential increase in their concentration.
⚠️ In 1987, ozone levels dropped by 50%, leading to collective action on climate change.
🌍 The success in addressing the ozone layer depletion was due to personal understanding, perceptible evidence, and practical solutions.
🔬 Scientists like Dr. Solomon played a crucial role in informing the public about the ozone layer depletion.
⚡️ The Montreal Protocol was established as a result of public awareness and recognized the adverse effects of ozone depletion on human health and the environment.
🌍 The Montreal Protocol is the only universal treaty to ever be ratified and is considered the most successful environmental agreement in human history.
📉 Since the implementation of the Montreal Protocol in 1989, the consumption of ozone-depleting substances has significantly decreased.
📌 The ozone layer has stopped growing and is now shrinking, expected to recover by 2065.
🌍 Hydrofluorocarbons (HFCs) are a potent greenhouse gas contributing to climate change.
⏰ Experts warn of the urgency to address climate change before 2030 to avoid catastrophic consequences.
🌍 Climate change is a pressing issue that we need to address.
🛡️ The ozone layer is no longer a major concern, but we should still be vigilant.
🌱 There are practical solutions available to protect the environment.
