They destroy ozone. Ozone is important because it blocks harmful UV radiation. CFC's are purely an anthropogenic chemical, and many of them are now banned.
Chlorofluorocarbons (CFCs) are the most harmful refrigerants to stratospheric ozone. When released into the atmosphere, they degrade ozone molecules, leading to the formation of the ozone hole. These compounds have been phased out under the Montreal Protocol due to their detrimental impact on the ozone layer.
Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are greenhouse gases that are harmful to the ozone layer. When released into the atmosphere, they break down ozone molecules and contribute to the depletion of the ozone layer, leading to increased exposure to harmful UV radiation.
Chlorofluorocarbons (CFCs) are the most harmful to stratospheric ozone because they contain chlorine atoms that can catalyze the destruction of ozone molecules in the upper atmosphere. This ozone depletion can lead to negative effects such as increased UV radiation reaching the Earth's surface.
Nitrates are contaminants of water and soils.
Ozone
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
Some refrigerants have chlorofluorocarbons that are harmful to the ozone layer. The CFCs can lead to rapid depletion of the ozone layer in the atmosphere.

because of chlorofluorocarbons
Old fridges typically use chlorofluorocarbons (CFCs) as the refrigerant gas. These gases have been phased out due to their harmful effects on the ozone layer.

Chlorofluorocarbons should not be used to replace anything; they're harmful to the ozone layer.
Chlorofluorocarbons (CFCs) play a significant role in ozone depletion in the atmosphere. When released into the atmosphere, CFCs break down and release chlorine atoms, which then react with ozone molecules, leading to the destruction of the ozone layer. This depletion allows more harmful ultraviolet radiation from the sun to reach the Earth's surface, contributing to environmental concerns such as increased skin cancer rates and disruptions to ecosystems.
Increased chlorofluorocarbons in the atmosphere can lead to the depletion of the ozone layer, which protects vegetation from harmful ultraviolet radiation. This can result in reduced plant growth, disrupted photosynthesis, and potentially harm overall plant health. Increased UV radiation can also contribute to a decline in worldwide vegetation productivity.
