how the change in the size of ozone layer effects the life of people on earth?????

 Hi yatharth,

Ozone is Earth's natural protection for all life forms. It shields our planet from the UV radiations. As these ultraviolet rays are  harmful for all the living things. Therefore any change in the size of this layer will automatically affect the life of people, plants and animals living on earth.

Hope you have got the answer.

Cheers !!
