Yes they are. They react with ozone and deplete it.
Yes
Because they got mad at them for not helping them fight against the syrians
Every country in the world approved the 1987 Montreal Protocol, which led to the phasing out of the production of CFCs (chlorofluorocarbons), the major cause of ozone destruction in the atmosphere.

Refrigerators often use refrigerant gases like Freon to cool the air inside. These gases absorb heat when they evaporate and release it when they condense, helping to keep the refrigerated space cool. However, newer refrigerators now use more environment-friendly refrigerant gases due to the harmful effects of Freon on the ozone layer.
Helping Wolfwing would give you free membership and destroying him would give you 100,000 AC'S.
Drones will benefit us the most in the future by helping to track and destroy terrorist groups.
cutting down the trees to use the land for their factories or to use as a farm for cattle so that we can have beef.
The answer is yes , the chemicals affecting ozone layer can be controlled. Ozone layer is found in stratosphere which is one of the layers of atmosphere. Ozone layer mainly gets depleted due to CFC's , CO2 and CH4 etc . Scientists are developing the alternative for the current referigerants that is CFC's for minimising the damage to the ozone layer and also if we get our vehicles pollution free , then the toxic gases would not get emitted into the environment. And planting more trees is always the best option for helping the mother Earth. Burning of the fossil fuels must be avoided.
Proper sanitation controls and reduces pathogens. It doesn't necessarily destroy them.
Refrigerators have double walls to provide insulation, which helps maintain a consistent temperature inside the fridge. The insulation reduces the amount of heat transfer between the inside and outside of the refrigerator, making it more energy efficient and helping to keep food cold.
