Why is a thin ozone layer over Antarctica of particular concern to scientists?
It is our primary protection from strong UV-B electromagnetic radiation from the sun.
On earthly life-forms, excessive UV-B exposure (in the event of low ozone levels) has a number of detrimental effects, such as the induction of cancer and severe sunburn.

A thin ozone layer over Antarctica is of particular concern to scientists because it leads to the formation of the Antarctic ozone hole. This hole allows harmful ultraviolet (UV) radiation from the sun to penetrate the Earth's atmosphere, increasing the risk of skin cancer, cataracts, and other health problems in humans and animals. Additionally, increased UV radiation can disrupt ecosystems, damage marine life, and inhibit the growth of phytoplankton, which serves as a foundation of the marine food chain. Therefore, the thinning of the ozone layer over Antarctica poses significant environmental and health risks, making it a focal point of scientific research and international efforts to address ozone depletion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
