(7a) Pollution refers to the presence of harmful substances or waste in the environment that can have negative impacts on the health of living organisms or the quality of the air, water, and soil.
(7b)
(I) Chemical pollution: This type of pollution occurs when harmful chemicals, such as pesticides and industrial waste, are introduced into the environment. These chemicals can contaminate the soil, water, and air, and can have negative impacts on the health of plants, animals, and humans. For example, the use of pesticides on agricultural land can lead to the contamination of the soil, which can then be absorbed by plants and enter the food chain.
(II) Physical pollution: This type of pollution occurs when solid waste, such as plastic and other debris, is improperly disposed of and accumulates on the land. This waste can have negative impacts on the appearance of the land and can also pose a threat to the health of plants and animals.
For example, large amounts of plastic waste can accumulate on the land, which can then be ingested by animals, leading to illness or death.
(III) Biological pollution: This type of pollution occurs when harmful biological agents, such as bacteria and viruses, are introduced into the environment. These agents can contaminate the soil, water, and air, and can have negative impacts on the health of plants, animals, and humans.
For example, the introduction of non-native species into an ecosystem can lead to the spread of disease, which can then harm the native species and disrupt the ecosystem.
