What are the impacts of stratospheric ozone? Explain

The stratosphere plays a crucial role in maintaining the Earth’s environmental balance. One of its most vital functions is the formation and maintenance of the ozone layer, which is situated between approximately 15 and 35 kilometers above the Earth’s surface. The ozone layer absorbs most of the Sun’s harmful ultraviolet (UV) radiation, preventing it from reaching the Earth’s surface in damaging quantities. This layer protects not only human health but also various ecosystems, including marine and terrestrial life forms. However, the degradation of the ozone layer has resulted in significant environmental concerns, particularly in relation to environmental health. This degradation primarily arises from the release of certain human-made chemicals, such as chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances (ODS). 

The impact of stratospheric ozone depletion is far-reaching and multifaceted. It affects both the environment and human health, and in this context, it is essential to understand the specific repercussions in terms of ultraviolet radiation, climate change, ecosystems, and public health.

### 1. Increased Ultraviolet Radiation

Ozone depletion directly leads to an increase in the amount of ultraviolet (UV) radiation reaching the Earth’s surface. UV radiation is classified into three categories based on wavelength: UV-A, UV-B, and UV-C. The ozone layer primarily absorbs UV-B and UV-C radiation, ______ _______ ________ ____ _________ ______ _____ _____.
