The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Non-Biodegradable Pollutants**: - Non-biodegradable pollutants are substances that cannot be broken down by microorganisms. This means they do not decompose naturally and can persist in the environment for a long time. 2. **Identifying Characteristics of Non-Biodegradable Pollutants**: - These pollutants accumulate in the environment and can cause significant harm to ecosystems. They can pollute air, water, and soil. 3. **Examples of Non-Biodegradable Pollutants**: - Common examples include: - **Polythene**: Plastic bags that do not decompose. - **DDT**: A pesticide that remains in the environment. - **Glass**: Does not break down naturally. - **Thermocol**: Used in packaging, it also does not decompose. 4. **Sources of Non-Biodegradable Pollutants**: - Non-biodegradable pollutants are primarily created by human activities. They are not naturally occurring substances but are produced for various purposes such as packaging, agriculture (insecticides), and other industrial processes. 5. **Analyzing the Options**: - The question provides four options: nature, excessive use of resources, humans, and natural disasters. - Since non-biodegradable pollutants are primarily a result of human activities, the correct answer is **humans**. ### Final Answer: **Non-biodegradable pollutants are created by: Humans.** ---
