Question

What type of pollution does household waste cause?

• A. Soil pollution
• B. Water pollution
• C. Air pollution
• D. All of these

Hint:

When considering the impact of a broad source like "waste," think about all the possible ways it interacts with the environment: on land (soil), in water (water), and in the air (air).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Household waste, if not managed properly, can be a significant source of environmental pollution. The question asks to identify the types of pollution it can cause.

Step 2: Detailed Explanation:
Improper disposal of household waste can lead to all three types of pollution:
- Soil pollution: When waste is dumped in landfills, harmful chemicals and liquids (leachate) can seep into the soil, contaminating it.
- Water pollution: The leachate from landfills can also contaminate groundwater. Furthermore, dumping waste directly into rivers, lakes, or oceans causes severe water pollution.
- Air pollution: Burning household waste releases toxic gases and particulate matter into the atmosphere. Also, the decomposition of organic waste in landfills produces methane, a potent greenhouse gas.
Since household waste can contribute to all three, the correct answer is 'All of these'.

Step 3: Final Answer:
Household waste can cause soil, water, and air pollution.
