Answer 1

1.) Short term health effects when exposed to voc's are headaches, dizziness, Eye irritation, visual disorder.

Long term health effects when exposed to voc's are

1.)eye, nose, throat irritation for long period.

2.) Liver, kidney, nervous system damage.

3.) Some cancers may attack due to over exposure of these voc's.

2.) Human activities destroyes ozen layer by releasing green house gases by using air conditioners, automobiles, refrigerators etc.

Natural ways that causes ozone depletion are due to heat, time, uv Ray's intensity, by transfer of chlorine atoms to the atmospheres ozone layer where provides photo catalysts decay path.

3.) ozone layer plays a crucial role in global warming where it defends the earths surface for uv rays from directly falling on earth by forming a thin layer in between if this ozone layer got destroyed the earth gets heated up with abnormal temperatures that affects the total earths natural processes.

4.) the 1987 montreal protocol is that which is designed for protection of ozone from getting depleted by tracing out the activity that causing ozone depletion and taking necessary actions to regulate that.
