Essay on Environment and Environment Pollution
The term "environment" refers to the natural setting in which we live. It refers to an ecological awareness. The ecosystem that includes human beings, plants, animals, birds, reptiles, insects, water bodies, fishes, , trees etc is called environment.
We find the physical, social, and cultural environment around us. All living things are parts of environment.
Pollution is the introduction of contaminants into the natural environment. It has adverse effect on environment. Major types of pollution include: Air pollution, light pollution, littering, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, water pollution.
Environment plays a crucial role in the healthy living of human beings. It is the only home that humans live, and it provides air, food, and other needs.But due to pollution many species are losing its life.
Humanity's entire life support system depends on the well-being of all the environmental factors.
Environment maintains the ecological balance on earth. It provides water, food, shelter, air for all. It is the source of natural beauty. The forest and trees filter the air and absorb harmful gases. Plants purify water.
Most air pollution comes from energy use and production. When we burn petrol or diesel or coal to run our cars, machines, trains, power plants etc. this releases harmful pollutants into the atmosphere. Its causes include burning of fossil fuel and firewood, smoke released from factories, volcanic eruptions, forest fires, bombardment, asteroids, CFCs (Chlorofluorocarbons), carbon oxides and many more.
It is the duty of human being to maintain ecological balance by saving nature via environment. We shouldnt forget that nature is a visible form of god.
