|  Pollution
has become a major issue over the years. It has caused death, disease,
and many health problems. It is a major concern of our world today and
not much is being done to prevent it. If not all, a lot of pollution is
caused by humans. There are different types like industrial,
agricultural, etc. Many people are realizing now the threat that
pollution poses to humans.
There are three main types of
pollution. They are land, air, and water pollution. Land pollution deals
with dumps or other harmful substances. Strip mining, digging, and
irrigation are types of land pollution also. They aren’t as harmful to
us but they scar and hurt the land. Landfills are a major source of
pollution. Most are infested with disease or with animals carrying
disease. Many contain harmful chemicals that seep into the land or g
asses that cause explosions or fires. Solid and hazardous wastes are
found in landfills and dumps. Solid wastes are the most visible form of
land pollution. Every year, humans dispose of billions of tons of solid
wastes. Most of our disposal methods cause harm to the environment.
Hazardous wastes are substances released into the environment that can
cause death or harm to people and their surroundings. These wastes are
very hard to dispose of and usually contaminate the environment quickly
To
regulate pollution, we first have to have an idea of what type of
effects it will have on the general population and then determine the
acceptable amount of exposure level. Since the specific risk here is
that the individual will get cancer, after being exposed to a pollutant,
possibly leading to their death, we have to consider a few factors such
as age, sex, and their health status
