What is the main concern regarding the depletion of the ozone layer?

The primary concern regarding the depletion of the ozone layer stems from its critical role in protecting life on Earth from the sun's harmful ultraviolet (UV) radiation. The ozone layer acts as a shield, absorbing most of the sun's detrimental UV radiation, particularly UV-B and UV-C, which can cause significant health and environmental issues.

In terms of human health, increased exposure to UV radiation as a result of ozone layer depletion is linked to a higher incidence of skin cancers, including melanoma and non-melanoma skin cancers. It also contributes to the development of cataracts, which can impair vision and lead to blindness if untreated.

Beyond health concerns, the reduction of the ozone layer can adversely affect the environment and agriculture. Increased UV radiation can damage phytoplankton, the foundation of the aquatic food web, thereby affecting marine ecosystems. In terrestrial ecosystems, crops and vegetation could be negatively impacted, leading to reduced agricultural productivity and food security.

Considering these critical aspects, the answer encompasses all the major concerns associated with ozone layer depletion: it contributes to increased temperatures due to potential changes in climate patterns, raises serious health issues like skin cancer and cataracts, and poses risks to agriculture. Therefore, selecting the option that includes all these elements is valid and reflects
