Question: how inductrial waste cause polution? 

Answer: Industrial wastes cause pollution in four major areas: air, water, soil and atmosphere. Those wastes that are gaseous pollute air that living things breath or use for food production as in plants. Gaseous wastes in air will either kill living things or disturb their normal processes. Gaseous pollutants also pollute our atmosphere that the atmosphere will lose its ability of blanketing the earth from hostile rays coming from the sun and space. Acid rain is as well caused by gaseous wastes. Wastes also pollute water bodies and soil and result in killing or disturbing the normal processes of living things specially plants.
