The word “pollution” indicates the presence on an unwanted foreign material into something. Hence, with reference to the earth, pollution means the contamination of our natural resources by different pollutants, produced mainly due to human activities. Today, pollution is the most significant issue that concerns the health of our environment.
Industries emanating toxic gases and insoluble waste, damage our natural resources of air, soil and water. There could be various examples of human induced pollutants, like – plastics, littering, radioactive contamination, soil contamination etc. Pollution must be dealt with immediately and globally as well. Natural resources, which we are losing due to pollution today, have been produced in millions of years and might take another Million to repair.
pollution occurs when pollutants contaminate the natural surroundings. Pollution disturbs the balance of our ecosystems, affect our normal lifestyles and gives rise to human illnesses and global warming. Pollution has reached its peak due to the development and modernization in our lives. With the development of science and technology, there has been a huge growth of human potentials. People have become prisoners of their own creations. We waste the bounties of our nature without a thought that our actions cause serious problems. We must deepen our knowledge of nature`s laws and broaden our understanding of the laws of the human behavior in order to deal with pollution problems. So, it is very important to know different types of pollutions, their effects and causes on humanity and the environment we live in.
Types, causes, and effects of pollution
Air pollution is one of the most dangerous forms of pollution. A biological, chemical, and physical alteration of the air occurs when smoke, dust, and any harmful gases enter into the atmosphere and make it difficult for all living beings to survive as the air becomes contaminated. Burning of fossil fuels, agriculture related activities, mining operations, exhaust from industries and factories, and household cleaning products entail air pollution. People release a huge amount of chemical substances in the air every day. The effects of air pollution are alarming. It causes global warming, acid rains, respiratory and heart problems, and eutrophication. A lot of wildlife species are forced to change their habitat in order to survive.
Soil pollution occurs when the presence of pollutants, contaminants, and toxic chemicals in the soil is in high concentration that has negative effect on wildlife, plants, humans, and ground water. Industrial activity, waste disposal, agricultural activities, acid rain, and accidental oil spill are the main causes of soil pollution. This type of contamination influence health of humans, affects the growth of plants, decreases soil fertility, and changes the soil structure.
Water pollution is able to lead our world on a path of destruction. Water is one of the greatest natural resources of the whole humanity. Nothing will be able to live without water. However, we do not appreciate this gift of nature and pollute it without thinking. The key causes of the water pollution are: industrial waste, mining activities, sewage and waste water, accidental oil leakage, marine dumping, chemical pesticides and fertilizers, burning of fossil fuels, animal waste, urban development, global warming, radioactive waste, and leakage from sewer lines. There is less water available for drinking, cooking, irrigating crops, and washing.
Light pollution
Light pollution occurs because of the prominent excess illumination in some areas. Artificial lights disrupt the world`s ecosystems. They have deadly effects on many creatures including mammals, plants, amphibians, insects, and birds. Every year many bird species die colliding with needlessly illuminated buildings. Moreover, artificial lights can lead baby sea turtles to their demise.
