The Ozone Layer Our sky protector
Certainly! Let’s talk about the ozone layer, our celestial shield against harmful solar radiation. 🌍🛡️

The ozone layer is a crucial part of Earth’s atmosphere, situated approximately 15 kilometers (9 miles) above the planet’s surface. Here’s why it’s so important:

Absorbing Ultraviolet Radiation (UV):
The ozone layer acts as a filter for ultraviolet radiation (UVR) from the sun.
It effectively blocks almost all solar radiation with wavelengths less than 290 nanometers (nm) from reaching Earth’s surface.
This includes certain types of ultraviolet (UV) light, which could harm or even kill most living organisms1.
Types of UV Light:
There are two major types of UV light:
UVB: Responsible for skin conditions like sunburns and certain skin cancers (e.g., basal cell carcinoma and squamous cell carcinoma).
UVA: Penetrates more deeply and causes the deadly skin cancer melanoma and premature aging.
The ozone layer, our Earth’s sunscreen, absorbs about 98 percent of this devastating UV light, shielding life on our planet2.
Threats to the Ozone Layer:
Chlorofluorocarbons (CFCs) are chemicals found in refrigerants and plastic products.
Once CFCs reach the stratosphere, they start eating away at the ozone layer.
Ozone molecules (composed of three oxygen atoms) are naturally destroyed and reformed, but CFCs hinder ozone from reforming after being broken apart.
As a result, the ozone layer—making up only 0.00006 percent of Earth’s atmosphere—is thinning over time2.
In summary, the ozone layer is our sky protector, shielding us from harmful UV radiation and ensuring the well-being of life on Earth. 🌞🌎🌿
