Environmental Pollution : Definition & Types

61 / 100


Environmental pollution is a pressing global challenge that results from the introduction of harmful substances into the natural elements that sustain life—air, water, and soil. As human activities have intensified, so has the scale and complexity of pollution, leading to widespread environmental degradation. The air we breathe is tainted by industrial emissions and vehicular exhaust, contributing to respiratory issues and climate change. Water bodies, essential for life, face contamination from industrial discharges, agricultural runoff, and improper waste disposal, jeopardizing aquatic ecosystems and human health. Soil, the foundation of agriculture, is compromised by the accumulation of pollutants, affecting its fertility and posing risks to food safety. Noise pollution disrupts the sonic balance of our environments, impacting human well-being and wildlife. In the modern era, excessive artificial light not only obscures our view of the night sky but also disturbs natural ecosystems. Thermal pollution alters the temperature of water bodies, further threatening aquatic life. To address these challenges, concerted efforts are needed, including sustainable practices, technological innovations, and robust environmental policies, to ensure a healthier, cleaner planet for current and future generations.
