✯What is Pollution

Pollution is the introduction of contaminants into the natural environment that cause adverse change.Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed 9 million people worldwide.

✯Types of Pollution

• Air Pollution
• Water Pollution
• Soil Pollution
• Noise Pollution

➜What is Air Pollution

Air pollution refers to the release of harmful contaminants (chemicals, toxic gases, particulates, biological molecules, etc.) into the earth’s atmosphere. These contaminants are quite detrimental, and in some cases, pose serious health issues. Some causes that contribute to air pollution are:

• Burning fossil fuels
• Mining operations
• Exhaust gases from industries and factories

➜What is Water Pollution

Water pollution is said to occur when toxic pollutants and particulate matter are introduced into water bodies such as lakes, rivers and seas. These contaminants are generally introduced by human activities like improper sewage treatment and oil spills. However, even natural processes such as eutrophication can cause water pollution.

Other significant causes of water pollution include:

• Dumping solid wastes in water bodies
• Disposing untreated industrial sewage into water bodies
• Human and animal wastes
• Agricultural runoff containing pesticides and fertilisers

➜What is Soil Pollution

Soil pollution, also called soil contamination, refers to the degradation of land due to the presence of chemicals or other man-made substances in the soil. The xenobiotic substances alter the natural composition of soil and affect it negatively. These can drastically impact life directly or indirectly. For instance, any toxic chemicals present in the soil will get absorbed by the plants. Since plants are producers in an environment, it gets passed up through the food chain. Compared to the other types of pollution, the effects of soil pollution are a little more obscured, but their implications are very noticeable.

Some of the common causes of soil pollution are:

• Improper industrial waste disposal
• Oil Spills
• Acid rain which is caused by air pollution
• Mining activities
• Intensive farming and agrochemicals (like fertilisers and pesticides)
• Industrial accidents

➜What is Noise Pollution

Noise pollution refers to the excessive amount of noise in the surrounding that disrupts the natural balance. Usually, it is man-made, though certain natural calamities like volcanoes can contribute to noise pollution.

Noise pollution has several contributors, which include:

• Industry-oriented noises such as heavy machines, mills, factories, etc.
• Transportation noises from vehicles, aeroplanes, etc.
• Construction noises
• Noise from social events (loudspeakers, firecrackers, etc.)
• Household noises (such as mixers, TV, washing machines, etc.)

✯How to reduce pollution

➜Ways to Reduce Air Pollution

• Riding a bike or walking instead of driving.
• Taking a bus or carpooling.
• Buying a car that has greater fuel efficiency.
• Turning off lights and appliances when they are not in use.

➜Ways to Reduce water Pollution

• DO NOT pour fat from cooking or any other type of fat, oil, or grease down the sink.
• DO NOT dispose of household chemicals or cleaning agents down the sink or toilet.
• DO NOT flush pills, liquid or powder medications or drugs down the toilet.
• Avoid using the toilet as a wastebasket.

➜Ways to Reduce soil Pollution

• Eat sustainable foodstuffs, properly recycle batteries, produce homemade compost and dispose of drugs in the places authorised for this purpose.

• Encourage a more eco-friendly model for industry, farming and stock breeding, among other economic activities.

• Improve urban planning and transport planning and waste water treatment.

• Improve the management of mining waste, restore the landscape and conserve topsoil.

➜Ways to Reduce NoisePollution

• Turn off Appliances at Home and offices.
• Shut the Door when using noisy Machines.
• Use Earplugs.
• Lower the volume.
