Final answer:
Pollution is the introduction of contaminants into the environment, leading to adverse changes in ecosystems and potential damage to human health. It can result in contamination of natural resources, disruption of ecosystems, and release of harmful substances into the environment.
Step-by-step explanation:
Pollution is the introduction of contaminants into the natural environment, leading to adverse changes in ecosystems and potential damage to human health. It can occur in water, air, and land and can have various negative effects.
Contamination of natural resources is one environmental issue caused by pollution. For example, oil spills can contaminate freshwater supplies and pollute rivers and streams, while mining can lead to the destruction of land and loss of habitats.
Disruption of ecosystems is another issue caused by pollution. When pollutants are introduced into an ecosystem, it can disrupt the balance and functioning of the ecosystem, leading to negative consequences for plants, animals, and organisms that depend on it.
Release of harmful substances into the environment is a common effect of pollution. Industrial pollutants, hazardous waste, and other chemicals can be released into the air, water, or soil, causing harm to both the environment and human health.
