can they do?

Answer:
Effects of ozone depletion for humans and the environment
Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. ... UV radiation also affects terrestrial and aquatic ecosystems, altering growth, food chains and biochemical cycles.
The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. ... That is,the lower the ozone levels, the higher the solar UVR.
Ozone sits in the upper atmosphere and absorbs ultraviolet radiaton, another type of solar energy that's harmful to humans, animals and plants. CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.
