The U.S. banned the non-essential use of chlorofluorocarbons (CFCs) due to their significant role in ozone layer depletion, which increases harmful ultraviolet radiation reaching the Earth's surface. This decision was influenced by scientific evidence linking CFCs to the thinning of the ozone layer, leading to health and environmental concerns. The ban was part of a broader international effort, notably the Montreal Protocol, aimed at phasing out substances that harm the ozone layer.

Both "which had" and "that had" can be correct depending on the context. Use "which had" when providing additional non-essential information, and "that had" when providing essential information. For example, "I found the book, which had been missing for weeks" (non-essential) vs. "I found the book that had the missing chapter" (essential).
Use "which" to introduce non-essential clauses that provide additional information and can be omitted without changing the meaning of the sentence. Use "that" to introduce essential clauses that are necessary to the meaning of the sentence and cannot be omitted.
Use "which" with a comma before it if the information it provides is non-essential, meaning the sentence still makes sense without it. Use "that" without a comma if the information is essential to the sentence's meaning. Example: "I bought a car, which was blue." (non-essential, use a comma) "I like cars that are fast." (essential, no comma)
