Answer:
air pollution.
Step-by-step explanation:
Air Pollution: Pollution of air, water and soil take a huge number of years to recover. Industry and engine vehicle fumes are the most obvious toxins. Substantial metals, nitrates and plastic are poisons in charge of pollution. While water contamination is brought about by oil slicks, acid rain, and urban sprawl; air contamination is created by different gasses and poisons discharged by businesses and manufacturing plants and burning of fossil fills; soil contamination is majorly created by mechanical waste that takes supplements out of the soil.
