I am conducting a survey for our school project. So it would be very helpful if you provide me with your educational level, experience, background and age.
HFC is an alternative of CFCs in refrigerators and air conditioners and it doesn't harm ozone layer. But HFCs are greenhouse gases.
CFC substitues such as propane, isobutane and butane are extremely flammable.
Every compound has its risks. Do you think it was reasonable to ban CFCs when its alternatives also have enough risks?
