What causes acid rain?

Acid rain occurs when sulfur dioxide (SO2) and nitrogen oxides (NOx) are emitted into the atmosphere and carried by air currents and winds. SO2 and NOx react with water, oxygen, and other chemicals to form sulfuric and nitric acids. It then mixes with water and other materials before seeping into the ground, causing harmful effects.

The main source of sulfur dioxide and nitrogen oxides that cause acid rain comes from burning fossil fuels for energy: two-thirds of the sulfur dioxide and one-quarter of the nitrogen oxides in the atmosphere can be traced to electricity generators. In addition, the exhaust gases of cars, trucks and buses also release nitrogen oxides and sulfur dioxide into the air and cause acid rain.


Climate change is not only increasing wildfires, but also air pollution. Burning of tree stubble and agricultural residues is also a major contributor to forest fires. It causes an increase in PM2.5 in the air which collides with other harmful substances such as chemical gases and pollen to form smog. Smog makes the air hazy and makes it difficult for people to breathe. Visibility is also reduced as a result of this smog. Symptoms of smog inhalation include difficulty breathing, irritation of the eyes, nose and throat, itching of the respiratory tract, etc.

  • Even 90% of forest fires are caused by human causes, a small spark can turn hectares of forest area into ashes.
  • Soot particles, dust and smoke (which contains many toxic chemicals) can float in the air for days.
  • The average temperature is increasing day by day due to the greenhouse effect. As a result, rising temperatures affect the rate of forest fires.
  • The higher the temperature, the more cases of forest and forest fires. Animals, plants and wild animals are affected by forest fires.

wastewater and wastewater

Harmful chemicals, bacteria and pathogens can be found in sewage and wastewater even when treated. Sewage and waste water from every home is discharged into the sea with fresh water. The pathogens and bacteria present in this wastewater cause disease and are therefore the cause of health problems for humans and animals.

The old phrase “like water and oil” is used when describing two things that don’t mix easily or at all. As it is said: water and oil do not mix, and oil does not dissolve in water. Large oil spills and leaks, though often accidental, are major causes of water pollution. Leaks and spills are often caused by oil drilling in the ocean or by ships carrying oil. wild animals.
