Why can ozone be considered beneficial in the upper atmosphere?

Ozone in the upper atmosphere, primarily found in the stratosphere, plays a critical role in protecting life on Earth by absorbing the majority of the Sun's harmful ultraviolet (UV) radiation. This layer of ozone acts as a shield, preventing UV rays from reaching the surface and consequently reducing the risk of skin cancer, cataracts, and other health-related issues in humans, as well as preserving various ecosystems. The beneficial function of ozone in absorbing UV radiation is essential for maintaining the health of both terrestrial and aquatic ecosystems, as this radiation can have detrimental effects on living organisms, including disrupting photosynthesis and harming marine life. The other options do not accurately reflect the role of ozone in the upper atmosphere.
