Hey, everyone! 

This month, our mentor told us to do the report about the "Chemical Product(human made or naturally produced) that affects the environment positively or negatively." , and I choose to do a link to my free report that I had talk about the depletion of ozone layer, so in this report I will introduce to you the chemicals that impact in the ozone depletion.

The chemicals that impact in the ozone layer have their production and importion controlled by the Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol). Some of there are:

- chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs): used in refrigerators and air conditioners;

- halons and hydrochlorofluorocarbons (HCFCs): are used in fire extinguishers;

- methyl bromide (CH3Br): is used to fumigation the soil;

- and the most famous of all is the chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) there are present in the aerosol propellants.

These substances are all used by all the humans in planet in day by day, but unfortunatelly the researchers didn't yet find substitutes for the chemicals, some of them are extremelly efective, like the methy bromide used in the soils. So, is responsability of all of us to use the products that contains the chemicals with conscience and thinking in the planet and how we can find solutions that are eco friendly until the researschers find soluions.

Green cheers from Brazil!!
