What are he various harmful effects …

Effects of Water Pollution:
·  Contaminated water becomes unfit for consumption by humans and cattle.

·  It results in drastic reduction of fish population. Fall in fish population results in loss of livelihood for fishermen.

·  Water pollution results in increased cases of water borne diseases; like cholera, diarrhoea, jaundice, etc.

·  Presence of faecal matter results in high concentration of E.coli in water; which causes water borne diseases.

·  Contamination of groundwater results in high levels of toxic materials in fruits, vegetables and grains.

Effects of Air Pollution:

• Carbon dioxide cause global warming because it is a potent greenhouse gas.
• Smog: Smog is a mixture of smoke and fog. Smog reduces visibility, and thus can create problems for drivers at highways. Pilots face problems while landing or taking off; due to smog.
• Carbon monoxide is a poisonous gas even at low concentration. It reduces oxygen carrying capacity of blood, and a person may die on exposure to carbon monoxide.
• Acid Rain: Oxides of sulphur and nitrogen mix with rainwater to create acid rain. Acid rain can be harmful for living beings and also for non-living things. Acid rain corrodes the outer surface of buildings. This has caused the Taj Mahal becoming pale.
• Suspended Particulate Matter in air can cause respiratory problems; like asthma and other respiratory disease.
• Greenhouse Effect: Greenhouse gases; like carbon dioxide and methane trap solar radiation and thus increase atmospheric temperature. This is called greenhouse effect.
• Global Warming: Overall increase in temperature of earth is called global warming.
