Environmental contamination refers to the presence of harmful substances in the natural environment, which can negatively impact ecosystems and human health. This contamination can occur through various means, such as industrial waste, agricultural runoff, and improper disposal of hazardous materials. Common contaminants include heavy metals, pesticides, and plastics. The effects of environmental contamination can be widespread, affecting air, water, and soil quality. For instance, polluted water sources can harm aquatic life and make drinking water unsafe for humans. Addressing environmental contamination often requires regulatory measures, public awareness, and community involvement to promote cleaner practices and protect natural resources.
