Answer:
High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complicationsLike humans, animals can suffer from a number of health problems due to air pollution, including birth defects, reproductive failure, and diseases.
Air pollution causes a number of environmental effects in addition to the effects on humans and animals.
Acid rain contains high levels of nitric and sulfuric acids that are created by oxides and sulfur oxides released into the air by the burning of fossil fuels. Acid rain damages trees and acidifies soils and water bodies, making the water too acidic for fish and other aquatic life.
Nitrogen oxides released into the air by the burning of fossil fuels also contribute to the nitrogen responsible for toxic algae blooms.
The release of man-made compounds including hydrochlorofluorocarbons, chlorofluorocarbons, and halons formerly used as coolants, foaming agents, pesticides, solvents, aerosol propellants, and fire-extinguishers are depleting the ozone. The ozone layer in the stratosphere forms a protective layer that reflects harmful ultraviolet rays back into space that would otherwise destroy animal and plant life.
Environmental 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.
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 wildlifespecies 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.
