An environment is the surroundings of a physical system that can interact with other systems by exchanging energy and mass. All living and non-living things fall under the natural environment. The environment is the surrounding in which we live, and therefore we must protect it from any destruction. An environmental pollution is one of the most significant problems facing human society today. Air, water, and soil form the three primary areas of environmental pollution.

When if there is an undesirable change in the surroundings that have harmful effects on animals and plants, thus it leads to environmental pollution. A pollutant is a substance that causes pollution. We can have pollutants in solid, gaseous, and liquid forms. A substance becomes a pollutant when its concentration is higher than the natural amount, and this increase in concentration is caused either by human activity or by natural phenomena. Some pollutants can be degraded and rapidly broken down by natural processes similar to the degradation of vegetables. We also have pollutants that take decades to break down and, once released, are not easily removed—for example, DDT, plastic materials, heavy metals, and nuclear waste. Pollutants are classified as significant pollutants, pool pollutants, and light pollutants. Pollutant concentrations are measured to determine public health risk assessments.
Pollutants were seen to originate at a certain point and then be carried to other places by the action of wind or water. Some pollutants are released into the soil by humans. Therefore, it leads to air, water, and soil pollution. If the soil is polluted, its useful microorganisms will die, and soil fertility will be lost. Crop production will decrease. It will have a detrimental impact on human society if the soil is not fertile.
Similarly, if the water is polluted, we must clean it before drinking it. Cleaning needs resources. Finally, if the air is polluted, breathing will become a problem, and the survival of life will be threatened. Air pollution also leads to many respiratory diseases and damages the human organism.
We can conclude that environmental pollution will affect life on Earth and should be limited as much as possible. We are harming nature; on the contrary, nature will harm us even more. This should be stopped, and our survival depends on this environment. So you need to be careful and maintain its balance.
- Air Pollution
Air pollution refers to any chemical, physical or biological change in the air. It is the contamination of the air with harmful gases, dust, and smoke that drastically affects plants, animals, and people.
There is a certain percentage of gases in the atmosphere. An increase or decrease in the composition of these gases is detrimental to survival. This imbalance in the composition of gases results in an increase in the Earth's temperature, which is known as global warming.
Types of Air Pollutants
There are two types of Air pollutants:
- Primary Pollutants
- Secondary Pollutants
- Noise Pollution
The noise is derived from the Latin word "nausea," a disease in which a person feels the need to vomit. Noise is an unpleasant and unwanted sound that causes discomfort to people. Sound intensity is measured in decibels (dB). The weakest sound that the human ear can hear is 1 Db. Due to the increasing noise around civilizations, noise pollution has become a subject of interest. Its main causes are vehicles, airplanes, industrial machinery, loudspeakers, crackers, etc. Some other devices like television, transistor, radio, etc. also contribute to noise pollution when used at high volume.
Types of Noise Pollution
Following are the three types of pollution:
- Transport Noise
- Neighborhood Noise
- Industrial Noise
- Soil Pollution
Soil pollution refers to soil contamination with anomalous concentrations of toxic substances. It is a serious environmental problem because it harbors many health risks. For example, exposure to soil that contains high concentrations of benzene increases the risk of leukemia.
It is most important to understand that all soils contain compounds that are harmful/toxic to humans and all the living organisms. Therefore, the concentration of such substances in unpolluted soil is low enough that it poses no threat to the surrounding ecosystem. When the concentration of one or more toxic substances is high sufficient to cause harm to living organisms, the soil is considered contaminated.
Cause of soil pollution are mentioned below:
- Excessive industrial activity
- Poor management or inefficient disposal of waste
- Agriculture (excessive/improper use of pesticides)
- Water Pollution
Water pollution can be known as the contamination of water bodies. Water pollution is caused when bodies of water such as rivers, lakes, oceans, groundwater, and aquifers are contaminated by industrial and agricultural wastes. When water becomes polluted, it adversely affects all life forms that directly or indirectly depend on that resource. The water consequences of contamination can be felt for years.
Sources Of Water Pollution
- Social and Religious Practices
- Use of Detergents and Fertilizers
- Industrial effluents
- Agricultural run-offs- Use of insecticides and pesticides
Q1. How can we maintain environmental pollution?
Ans. Eliminate or reduce fireplace and wood stove use. Reduce the number of trips you take in your car. Avoid burning leaves, trash, and other materials. Avoid using gas-powered lawn and garden equipment.
Q2. Who is responsible for environmental pollution?
Ans. All of us, but the government has crucial responsibility. "Who should take major responsibility in solving environmental problems - people (individual, group) or state? "In principle, all and everyone. State (state administration) and society (local government).
Q3. Who can improve the environment?
Ans. Few choices for a healthier planet.
- Reduce, reuse, and recycle. Cut down on what you throw away
- Volunteer. Volunteer for cleanups in your community.
- Conserve water
- Choose sustainably
- Shop wisely
Q4. What will happen if we do not protect the environment?
Ans. As ecosystems unravel, the quality of life for all species, including humans, will diminish. When ecosystems are compromised, the natural goods they provide – clean air and water, crop pollination, and storm protection – will inevitably decline.
Q5. How can cities prevent pollution?
Ans. Public buses, trams, subways, and trains are not only more affordable than driving your own car, they also help reduce air pollution. Sometimes, there are discounts for children, students, seniors, and weekly/monthly/yearly passes.
