Humans are often harmed by pollution. The presence of the hazardous substances
brought about by these three major types of pollution: land, air and water gravely affects our
health. For instance, a person may acquire skin problems and other deformities from the toxic
wastes present in the land that we live in such as garbage, pesticides, heavy metals and other
chemicals. Air pollution caused by toxic gases, solid and liquid particles or aerosols, and other
hazardous air pollutants adversely contaminate the air that we breathe. Long-term exposure to air
pollutants has been linked with diseases of the heart and lungs, cancers and other health
problems. Lastly, water pollution observed in our primary water sources like oceans, rivers, an
lakes is caused by the presence of industrial wastes, sewage and waste waters, chemical fertilizer
and pesticides to be specific. Infectious diseases can be acquired through contaminated water ar
can cause cholera, jaundice, liver damage and stomach illness in people.
