What is Pollution?
Pollution or contamination is the introduction of harmful materials into the environment. These materials, called pollutants, can be natural or man-made.
Air Pollution
Air pollution refers to the release of harmful chemicals and particulate matter into the atmosphere. These pollutants include carbon monoxide, sulfur dioxide, nitrogen oxides, and volatile organic compounds, which are primarily emitted from industrial processes, vehicle exhaust, and the burning of fossil fuels. Air pollution contributes significantly to climate change by enhancing the greenhouse effect, resulting in global warming and extreme weather patterns.
Water Pollution
Occurs when harmful substances, such as chemicals, waste, and pathogenic microorganisms, are introduced into rivers, lakes, oceans, and groundwater. These contaminants can originate from various sources, including agricultural runoff, industrial discharges, sewage, and plastic waste. Polluted water poses severe risks to aquatic ecosystems, leading to the death of marine life and the disruption of biodiversity.
Soil Pollution
Soil pollution is the degradation of land quality due to the accumulation of toxic substances such as heavy metals, pesticides, and industrial waste. These pollutants can enter the soil through agricultural activities, improper waste disposal, and industrial emissions. Contaminated soil can have severe consequences on the environment, affecting plant growth and leading to the loss of fertile land.
