The major source of noise pollution worldwide is due to:
a. office equipment
b. transport system
c. sugar, textile and paper industries
d. oil refineries and thermal power plants
Since transportation uses a lot of energy and produces a large amount of the world's oil, its impact on the environment is significant. This results in air pollution, such as particles of nitrous oxides, which contribute significantly to global warming through carbon dioxide emissions. The human heart may be affected by high noise levels and a higher incidence of coronary heart disease. By changing an animal's ability to identify and escape predators or prey, interfering with reproduction and navigation, and causing irreversible hearing loss, noise can raise an animal's chance of dying. Hence, (b) is the correct option.
