Essay On Pollution And Its Effects On Environment – Essay 3 (400 words)
Introduction
Pollution is the presence of contaminants in natural environment that adversely affect all living things. The components of pollution can be either naturally occurring components or foreign substances. The major forms of pollution include; air pollution, noise pollution, water pollution, plastic pollution, soil contamination, thermal pollution and light pollution.
Effects of Pollution on Environment
Environment includes all the living and non-living components. Plants, animals and other living creatures are important part of environment but environment also includes, air, water and land. Pollution in the environment affects it negatively. Given below are the adverse effects of pollution on environment:
Air pollution: Pollution pollutes the air that we breathe. It may cause harm to the living organisms such as animals, plants and other living organisms that are important part of our environment. It also damages our natural environment and degrades the quality of the air. The pollutants can occur naturally or can be manmade.
Ocean acidification: Emission of carbon dioxide causes ocean acidification. It is the decrease in the pH of the earth oceans by increase in the carbon dioxide in the atmosphere getting dissolved in the oceans.
Global warming: The emission of greenhouse gasses in the environment leads to Global warming which affects the ecosystem significantly.
Soil contamination: The quality of soil can degrade and it may become infertile and inappropriate for plants. This also affects the organisms in the natural food cycle. Nitrogen oxides and sulfur dioxide can cause acid rains which reduce the pH value of soil and can have harmful effects on plants, aquatic animals and infrastructure.
Decrease in biodiversity: Invasive species can surpass native species and can decrease biodiversity.
Plants: Smog and haze can lessen the amount of sunlight received by plants to carry out the process of photosynthesis.
Water: Pollution of water channels can reduce the oxygen levels and the diversity of species.
Biological magnification: It is the increase in concentration of toxins that may pass through tropic levels. It refers to the build-up of toxins in the food web. Predators accumulate more toxins than prey in the food chain.
Conclusion
Thus, pollution in the environment contaminates and reduces the quality of air water and land. Humans, animals, plants and other living organisms are a vital part of environment that gets effected due to pollution. Pollution is a global issue and needs serious attention. Various measures need to be taken to prevent pollution in the environment.
Answer:
Environment is the surroundings in which we live. But the contamination of our environment by pollutants is environmental pollution. The current stage of the earth that we are seeing is the cause of centuries of exploitation of earth and its resources.
Moreover, the earth cannot restore its balance because of environmental pollution. The human force has created and destroyed life on earth. Human plays a vital role in the degradation of the environment.
The environmental pollution, directly and indirectly, affects the lives of humans and other species. These living beings co-existed on the earth with human from centuries.
Effect on Air
Carbon and dust particles string up with the air in the form of smog, damaging respiratory system, haze, and smoke. These are caused by the emission of industrial and manufacturing units by burning of fossil fuels, vehicle combustion of carbon fumes.
Moreover, these factors affect the immune system of birds which become a carrier of viruses and infections.
Besides, it also affects the body system and body organs.
Effects on Land, Soil, and Food
Human’s organic and chemical both waste harm the land and soil with its decomposition. Also, it introduces some chemical in the soil and water. Land and soil pollution mainly caused by the use of pesticides, fertilizers, soil erosion, and crop residues.
Effect on Water
Water gets contaminated easily with any pollutant whether it is human waste or chemical discharge from factories. Also, we use this water for irrigation of crops and drinking. But, because of infection they become contaminated too. Besides, an animal dies because they drink this same contaminated water.
Moreover, around 80% of pollutants of land such as chemical, industrial and agricultural waste end up in the water bodies.
Besides, these water bodies ultimately connect to the sea which means it indirectly pollutes the biodiversity of the sea.
Effect on Food
Because of contaminated soil and water, the crop or agricultural produce also get toxic. Furthermore, this contaminated food effect our health and organs. From the beginning of their life, these crops are laced with chemical components that reach a mass level until the time of harvest.
