Question

Substances which are replacing CFCs = _______

Answer 1

Substances which are replacing CFCs are given below:

• The earth's protective ozone layer is destroyed by chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons, which shield the earth from damaging ultraviolet (UV-B) rays released by the sun.
• CFCs and HCFCs also warm the earth's lower atmosphere, causing global climate change.
• Hydrofluorocarbons (HFCs) also contribute to global warming.
• The Minnesota Pollution Control Agency (MPCA) is collaborating with industry, people, and the government to limit the harm that CFCs, HCFCs, HFCs, and related chemicals cause to the ozone layer and global climate.
