Answer with Explanation:
As a grade 5 student, I can prevent the ozone layer depletion by not using aerosol sprays such as insect repellant sprays or insect repellant lotions. The ozone layer's depletion is primarily caused by the chlorofluorocarbons (CFCs), a chemical made by humans. These CFCs are also present in insect repellants. Thus, preventing the use of it, will help heal the ozone layer.
When it comes to the effects of ozone layer depletion, it is important for me as a grade 5 student to wear protective clothing whenever I go out and use a sunscreen lotion. The UV rays cause skin cancer, thus wearing proper clothing and putting on sunscreen lotion will lessen the effects.
Further Explanation:
The CFCs can be found in aerosol sprays and are released into the air. Some of it manage to reach the stratosphere where they are met by UV rays. The radiation breaks them apart, thus releasing their chlorine atoms. These atoms try to find a pair to bond with in the atmosphere and once it gets paired with bromine, the reaction kills the ozone molecules thereby resulting to ozone layer depletion.
