What role does ozone play in protecting life on Earth?

Ozone plays a crucial role in protecting life on Earth primarily by absorbing harmful ultraviolet (UV) radiation from the sun. The ozone layer, located in the stratosphere, acts as a protective shield, filtering out a significant portion of the UV radiation that could otherwise reach the Earth's surface. Excessive exposure to UV rays can lead to a variety of health issues, including skin cancer, cataracts, and weakened immune systems, as well as detrimental effects on ecosystems and wildlife.

While oxygen is necessary for respiration, it is not provided by ozone; rather, breathable oxygen is primarily the result of photosynthesis. Additionally, ozone does not play a direct role in absorbing carbon dioxide, which is a greenhouse gas involved in climate regulation. As for weather formation, while ozone does influence atmospheric dynamics, its primary function in the context of life protection is its ability to absorb UV radiation. Thus, the role of ozone in filtering UV rays is vital for maintaining the health of living organisms and the integrity of the environment.
