Question

Which of the following is the major cause of pollution?
A. Plants
B. Man
C. Fungi
D. Hydrocarbon gases

Answer 1

Hint: Pollution is a very major issue of our environment; there are many types of pollution that causes harm to the environment like; water pollution, soil pollution, and air pollution. The soil pollution is caused due to soil erosion.

Complete Answer:
- There are different sources of pollution and each has a particular effect on the environment and living organisms. The pollution is not caused just because of carbon emissions and fossil fuels, but there are many more pollution including chemical pollution in water bodies and soil due to improper disposal of agriculture activities and release of chemicals.
- The noise pollution is also a major type of pollution that is caused due to the sounds produced in cities and urban areas. The air pollution is one of the major environmental pollution that we face. The air pollution is divided into primary and secondary pollution.
- The primary solutions are released directly from the source while the secondary pollution produced when primary pollutants react in the environment.
- For example; the burning of fossil fuels for electricity production and running of transportation are both primary as well as secondary pollutants and the biggest source of air pollution. The fumes released from the car contain many dangerous gases like nitrogen oxide, hydrocarbons, and carbon monoxide. These gases when rise into the atmosphere react with the atmospheric gases and form very toxic gases.
- So, hydrocarbons are one of the major causes of pollution. They are non-biodegradable compounds and are the secondary pollutants. The hydrocarbons are produced either due to incomplete combustion of fuel or sometimes naturally.

Thus, the correct option is ‘D’. Hydrocarbon gases.

Note: Ammonia is a primary pollutant found in air produce from agricultural activities. These compounds when enter in the air as a gas they get combined with the pollutants like sulphates and nitrogen oxides that are used to produce aerosols and cause air pollution.
