Chapter Content
Industries are responsible for four types of pollution: (a) Air (b) Water (c) Land (d) Noise.
Detailed Explanation
Industries contribute significantly to pollution in various forms. These include:
1. Air Pollution: Pollution caused by harmful gases and particulate materials released into the atmosphere.
2. Water Pollution: Pollution occurring when waste from industries contaminates water bodies.
3. Land Pollution: Pollution due to hazardous waste damaging the soil.
4. Noise Pollution: Disturbance caused by excessive noise from industrial operations.
Examples & Analogies
Think of a factory. It’s like a birthday party where everyone brings a gift, but if some guests bring noisy toys, while others bring food that spills everywhere – the noise and mess can disrupt the fun for everyone. Similarly, industries can pollute air, water, soil, and create noise, causing issues for our environment.
