Star Cluster will not forget the historical lessons that led to the ozone depletion of CFCs, and will continue to develop safer cleaning technologies that help preserve the global environment through cleaning technology, while keeping in mind the meaning of the natural environment and safety

Lessons from the Ozone Depletion Problem

The problem of ozone depletion has not been completely resolved.
However, it is true that the worldwide movement to reduce and ban the use of CFCs has somehow managed to prevent the occurrence of fatal damage to life on environmental crisis caused by chlorofluorocarbons (CFCs), which were promoted by the public and private sectors as the ultimate environmentally friendly cleaning agents, has left us
with many lessons to learn.
All living organisms and chemical substances generated on the earth have been verified by the earth itself over a long period of time as to their safety and value.
However, human-created products have been judged by human judgment on their relationship with the environment in a very short period of time.
I believe that the problem of ozone depletion teaches us how narrow and fragile human judgment can be when it is not verified by nature.
