How are wetlands polluted?

Wetlands can be polluted through various means, including agricultural runoff, which introduces fertilizers and pesticides, and industrial discharges that release toxic chemicals. Urban development often leads to increased sedimentation and the introduction of pollutants from stormwater runoff. Additionally, oil spills and wastewater discharge can severely impact the delicate ecosystems within wetlands. These pollutants disrupt water quality and harm the diverse flora and fauna that depend on these habitats.
