The ozone layer is significant because it acts as a protective shield in the Earth's stratosphere, absorbing and filtering out the majority of the sun's harmful ultraviolet (UV) radiation. This protection is crucial for life on Earth as it helps prevent skin cancer, cataracts, and other health issues caused by overexposure to UV radiation. Additionally, the ozone layer plays a role in regulating the Earth's climate by influencing atmospheric temperature and circulation patterns.
