Virtually all countries in the world agreed to ban the use of CFCs due to overwhelming evidence that they destroy the ozone layer. CFCs break down in the atmosphere and release chlorine, which destroys ozone molecules, leading to the thinning of the ozone layer. This thinning can lead to harmful ultraviolet radiation reaching the Earth's surface, causing skin cancer and other environmental problems.
