How does the depletion of the ozone layer affect humans?

The depletion of the ozone layer is primarily associated with an increase in ultraviolet (UV) radiation reaching the Earth's surface. The ozone layer acts as a shield, absorbing the majority of the sun's harmful UV rays. As this layer thins, more UV radiation penetrates the atmosphere, leading to higher exposure for humans.

One of the most significant health impacts of increased UV exposure is the elevated risk of skin cancer. Specifically, it has been linked to melanoma and non-melanoma skin cancers. Increased UV radiation can also cause other health issues, such as cataracts and other eye damage. Therefore, the connection between ozone depletion and an increased risk of skin cancer for humans is well established and backed by scientific research, making this option the correct choice.

In contrast, the other options do not accurately reflect the consequences of ozone layer depletion.
