Final answer:
Pollution refers to the introduction of contaminants into the environment, causing adverse changes to ecosystems and human health. It imposes costs on society, including health risks and financial instability. Historically marginalized communities often bear a disproportionate burden of health problems caused by waste and pollution.
Step-by-step explanation:
Pollution refers to the introduction of contaminants into the natural environment, leading to adverse changes in ecosystems and potential damage to human health. It can take various forms, such as the release of harmful substances into the air, water, or soil, as well as noise and light pollution.
Pollution imposes costs on society, including generating health and safety risks, disrupting communities, and causing financial instability. Communities, especially those historically marginalized, bear a greater burden of the health problems resulting from exposure to waste and pollution.
Examples of the unequal impact of environmental problems on communities include the water crisis in Flint, Michigan, where contaminated water led to health issues, and the South Bronx in New York City, where pollution from traffic has increased asthma diagnoses.
