Why is the depletion of the ozone layer concerning for Antarctica?

The depletion of the ozone layer is particularly concerning for Antarctica because it leads to increased levels of harmful ultraviolet (UV) radiation reaching the Earth’s surface. In Antarctica, where the ozone hole is most prominent, this heightened UV exposure can disrupt the delicate ecosystem, particularly affecting phytoplankton at the base of the food chain. Since phytoplankton are crucial to marine life and carbon absorption, their decline could have cascading effects on the entire Antarctic ecosystem and the global climate. Additionally, increased UV radiation poses health risks to both wildlife and any humans visiting or conducting research on the continent.
