Due to which climate change is happening (as harmful you. We rays from the sun is getting way to reach the earth as its thickness is decreasing) results in global warming.

As pollution increase all the chlorofloro carbons comes from our earth then ozone layer thickness is decrease as a result UV rays of sun directly comes on earth and causes us to cancer .

As global warming is increasing and people are cutting trees for their greed due to that global warming is increasing and amount of pollution is increasing in the enviorment thats the reason why we all are facing these problems occuring in our enviorment.

Due to deplenishing of ozone layer harmful uv rays reach the surface and results in causing cancer. Both cloroflurohydro carbons and methane gas are responsible for that.

STEPS OF OZONE LAYER DEPLITION-
1. CL + O3 - CLO + O2
2. CL + CLO - CL2+O

We know that stratosphere is rich in ozone gas. That's why ozone hole means decreasing of ozone layer in stratosphere.

Nothing else only we greedy humans are d cause of global warming.

Stratosphere mainly consists of ozone gas as the thickness of ozone is reduced mainly because of CFC CO2 CH4 etc.,

Ozone layer is present at the end of stratosphere.
