Industrial waste gets dumped into these water bodies. This causes a chemical imbalance in the water leading to death of the aquatic beings.
Insecticides, pesticides and ripening chemicals that are used on plants run into the ground water system or nearby streams.
Washing clothes near lakes and rivers causes detergents also causes a condition called “Eutrophication” which blocks sunlight from entering inside and reduces oxygen values in the water causing an inhabitable environment.
‘Oil Spills’ are caused when giant oil tankers and oil rigs which are present in the oceans are damaged by either natural or human errors cause a long-time damage to the ocean as oil is lighter than water and floats on water forming a layer blocking sunlight.
Certain natural disasters like flash floods and hurricanes cause the intermixing of water with harmful substances on the land. People can take certain preventable measures to stop water pollution like being more cautious of dumping contaminants onto the water. For the repair of the damage that has already been done, water treatment plants are being constructed with innovative techniques to clean the polluted water. But as always a certain part of the damage can be resolved therefore, it is better to prevent water pollution as water is basic need for the survival of man.
Air Pollution
The contamination of the air present in the atmosphere is known as “Air pollution”. Respiration is an important life process of all living things. We breathe in the air present in the atmosphere. Therefore if the air around us is contaminated with poisonous gases, it would have a fatal effect on us.

The air naturally comprises of 78% of nitrogen, 21% of oxygen, 0.9% of oxide gases and 0.1% of inert gases. When this balance is disturbed, it causes disruptions of severe proportions. What Causes Air Pollution?
