Why are scientists begin to worry about the levels of CFC in the atmosphere?

How does carbon dating help scientists?
Carbon dating helps scientists determine the age of organic materials by measuring the amount of carbon-14 present. By comparing the ratio of carbon-14 to carbon-12 in a sample to known levels in the atmosphere, scientists can calculate how long it has been since the organism died. This method is important for dating archaeological artifacts, determining the age of fossils, and understanding past climate changes.
