Even though there are about five times more elements that are metals than nonmetals, there are more nonmetals than metals found in compounds. Nonmetals form many more compounds than metals because living organisms are composed almost entirely of nonmetals. There are more than 8.7 billion living organisms on Earth.

Ozone is important in our atmosphere because it helps to protect all living things on Earth. Bad ozone is caused by pollution.
ACID RAIN and RUST are harmful because it contains harmful gases like sulphuric acid etc... mainly sulphur gasesbecause of this harmful gases when they reach the atmosphere when it rains it forms acid rain as the harmful gases mix with the atmosphere .This acid rain will affect plants,animals humans and all living organism.The acid mainly occurs at industrial areas because of these harmful gases which are released by the industrial effluents.they are definitely harmful to the atmosphere.
Ozone layer does not convert UV rays. It absorbs them.
The ozone layer present in the stratospheric region of the earth protects us from sun's harmful rays. These rays are very harmful and can cause various problems in living organisms.
Ozone present in the stratosphere is helpful as it blocks the harmful ultraviolet radiations from the sun. This ozone present in the atmosphere as ozone layer acts as a shield for earth against these harmful radiations.
They wouldnt be living things on this planet.
Absorption of carbon dioxide from the atmosphere modify the pH of waters; also the pollution from human activities.
