What impact might further depletion of the ozone layer have on the Antarctic region?

Further depletion of the ozone layer would have severe consequences for the Antarctic region, as it would allow more harmful ultraviolet (UV) radiation to reach the Earth’s surface. Increased UV exposure could disrupt the Antarctic food chain, starting with phytoplankton, which are highly sensitive to UV rays. Since phytoplankton form the foundation of the food web, their decline would impact krill, fish, and other marine life, potentially collapsing the entire ecosystem. Additionally, heightened UV levels pose risks to both wildlife and any human presence in the region, further stressing the fragile Antarctic environment and accelerating the effects of climate change.
