Hi there!
One of the main causes of air pollution is smoking.
Smoking affects not only humans, but pets and animals as well. Animals can get cancer too!
Another big cause of pollution is cars. Gasoline of course comes out into the air after it is used. It also affects animals.
A lot of people know that we should change this, but hardly anyone is really doing anything to try and stop it.
I know this is a short answer, but I hope it helps!

Explanation:
Atoms in molecules are bonded together via covalent bonds. Covalent bonds are bonds that are formed by sharing of the valence electrons between two atoms.
The atoms can be of the same kind or of different kinds.
- In most molecules, the two atoms are connected by sharing of their valence electrons.
- This way, each atom can attain stability by becoming isoelectric with the nearest noble gas.
- Some molecules are monoatomic, some are polyatomic.
