What type of pollution is created
from the mixing of human and animal waste with water? (A) Air pollution, (B) biological
pollution, (C) chemical pollution, (D) land pollution, (E) thermal pollution.
This question has to do with
pollution. Pollution is the introduction of
harmful materials called pollutants into the environment. There are three main types of
pollution. Land pollution may be caused by
mining, overfarming, landfills, accidental spills, or pesticides. Air pollution may be caused by the
burning of fossil fuels, the use of motor vehicles, fumes from paint or aerosol
sprays, as well as natural sources like wildfires. Water pollution may be caused by
industrial wastewater, farming, sewage, or nuclear power plants.
This question has to do with the
type of pollution created from the mixing of human and animal waste with water. So this question is about water
pollution, not air or land pollution. This means we can eliminate answer
choices (A) and (D).
Biological pollution, chemical
pollution, and thermal pollution are all types of water pollution.
Biological pollution is caused when
human and animal waste is disposed of in water sources, such as rivers and
lakes. Biological water pollution can lead
to the spread of diseases, such as bilharzia, typhoid, and hepatitis.
Chemical pollution often originates
from factories and is caused when chemical waste enters a water source. Chemical waste can increase the
concentration of harmful substances like mercury and lead that can result in damage
to the brain and other organs.
Thermal pollution is the artificial
rise or fall in the temperature of a water source. Changing water temperatures can
affect the amount of oxygen in the water, which can have disastrous effects on
marine organisms in the area.
From our discussion, we can see
that the type of water pollution caused from human or animal waste is biological
pollution. Therefore, the type of pollution
created from the mixing of human and animal waste with water is biological
pollution, answer choice (B).
