How does water get polluted so easily?

Water gets polluted easily due to a variety of human activities and natural processes. Industrial discharges, agricultural runoff containing fertilizers and pesticides, and sewage from urban areas contribute significantly to water contamination. Additionally, plastic waste and other pollutants can enter water bodies through stormwater runoff. Natural events, such as storms and floods, can also mobilize pollutants, exacerbating water quality issues.
