Which one of these measures would contribute more towards water pollution instead of reducing it?

Options

A. Using weedicides
B. Using biofertilizers
C. Installing sewage treatment plants
D. Using organic wastes to make manure

Explanation

**Step-by-Step Solution:**

1. **Understanding Water Pollution**: Water pollution occurs when harmful substances, known as pollutants, enter water bodies and exceed a tolerable limit. This can lead to negative effects on aquatic life and human health.

2. **Analyzing the Options**:
- **Option A: Using Weedicides**: Weedicides are chemicals used to kill unwanted plants (weeds). If these chemicals enter water bodies, they can contaminate the water, leading to increased pollution. Thus, this option contributes to water pollution.
- **Option B: Using Biofertilizers**: Biofertilizers are natural fertilizers made from microbes that enhance soil fertility without harming the environment. They do not contribute to water pollution.
- **Option C: Installing Sewage Treatment Plants**: The purpose of sewage treatment plants is to treat domestic sewage and make it reusable. This process helps reduce water pollution rather than contribute to it.
- **Option D: Using Organic Waste to Make Manure**: This practice involves recycling organic waste into useful manure, which improves soil health and does not lead to water pollution.

3. **Conclusion**: Among the options provided, using weedicides (Option A) is the measure that would contribute more towards water pollution instead of reducing it.

**Final Answer**: A. Using weedicides
