== Smoke from factories ==

[[factory|Factories]] and [[power plant]]s produce large amounts of smoke into the atmosphere which [[pollution|pollutes]] the air. Eventually the toxic [[chemical]]s in smoke fall to the ground, and then they pollute the soil and the [[water pollution|water]]. When the air, soil and water are polluted with toxic chemicals, the chemicals also get absorbed by [[plant]]s and [[animal]]s (including [[human]]s).

When [[Carbon dioxide#Dry ice|Dry ice]] is put into water, it creates '''smoke''', also. Dry ice is used for theatrical needs, and for places that need illumination.

When [[Carbon dioxide#Dry ice|Dry ice]] is put into water, the dry ice boils and makes [[fog]]. This is not real smoke but [[movie]] makers and other show people do this to simulate smoke.
