removing useful substances from water how it cause water pollution
sir, in your video lecture you have said that removing useful substances from the water causes water pollution eg- if we remove oxygen from the water it will affect the marine animals and it will cause water pollution but how removing oxygen cause water pollution and why do we need to remove oxygen from water. Explain.
When we remove the oxygen from the water it will affect the marine animal and aquatic plants. they will die. So they dead bodies will create the causes of water pollution.
-When we discharge the organic compounds like industrial wastes or sewage etc. in to the water bodies. Microorganisms living in the water use the oxygen to discompose these wastes and the remove the oxygen from the water.
-Hot water also reduce the oxygen from the water.
