What quirky fact about CFCs (chlorofluorocarbons) makes them notorious for ozone depletion?
✔✔CFCs were once considered "miracle chemicals" for their stability and non-toxic nature, but
they turned out to be stealthy villains, sneaking up to the stratosphere to wreak havoc on the
ozone.
How do scientists track the health of the ozone layer in real-time?
✔✔Scientists use sophisticated satellite technology and ground-based monitoring stations to
continuously observe and assess ozone levels and trends.
What creative solutions have been developed to replace ozone-depleting substances in everyday
products?
✔✔Innovators have introduced natural refrigerants, like hydrocarbons and CO2, as eco-friendly
alternatives that perform well without harming the ozone layer.
What unexpected benefit has arisen from the global commitment to the Montreal Protocol?
✔✔One unexpected benefit is the slowing of climate change, as phasing out ozone-depleting
substances also reduces greenhouse gas emissions.

, What intriguing connection exists between the ozone layer and climate patterns?
✔✔The ozone layer influences atmospheric circulation patterns, which can affect weather and
climate, creating a complex relationship between ozone depletion and climate change.
How do volcanic eruptions play a surprising role in ozone dynamics?
✔✔Volcanic eruptions can release large amounts of chlorine and sulfur dioxide into the
stratosphere, temporarily affecting ozone levels and potentially leading to short-term depletion.
What fun analogy can be used to explain the ozone layer’s function to a child?
✔✔The ozone layer is like a sunscreen for the Earth, blocking harmful rays from the sun and
keeping everything safe and healthy!
What are some everyday actions people can take to be "ozone heroes"?
✔✔People can be ozone heroes by choosing products labeled as “ozone-friendly,” properly
recycling old refrigerants, and advocating for policies that protect the environment.
How do scientists view the future of the ozone layer following the Montreal Protocol?
