Imagine the year 2030. It's early in the morning, and you go out to get the newspaper. When you return, you notice a blemish on your hand from the sun. This could be a reality in the near future.

This summer seems unusually hot and humid because our planetary sunscreen—the ozone layer—is being destroyed. We’ve all heard about the ozone layer, but what is it really? Is it only helpful, or can it be harmful too? When did we first become concerned about its depletion? Is it a real problem or just media hype? Can the damage be corrected?

These are the questions I will address in my speech about the environmental phenomenon known as the ozone layer.

Final answer:

The ozone layer is essential for shielding Earth from harmful UV radiation, and its depletion can lead to health risks and ecological disruptions. International agreements have helped reduce ozone-depleting substances, shrinking the ozone hole over Antarctica. Protecting skin and eyes from UV radiation is crucial due to the potential health effects of increased UV-B exposure.


Explanation:

Ozone is a vital layer in the stratosphere that shields Earth from harmful UV radiation, protecting life on the planet. Its depletion due to human activities like releasing chlorine and bromine gases can lead to an increase in UV radiation, posing risks such as skin cancer and disrupting ecosystems.

The ozone layer depletion became a significant concern in the 1980s, leading to international agreements to phase out ozone-depleting substances like chlorofluorocarbons (CFCs). As a result, the ozone hole over Antarctica is gradually shrinking, showcasing the impact of global efforts on environmental conservation.

UV-B radiation poses health risks, and even with normal ozone levels, sunlight contains UV-B light. Therefore, it's crucial to protect skin and eyes from the sun, as ozone layer depletion can elevate UV-B exposure and associated health issues.
