### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an agricultural practice that is profitable (wealthy) but not good for the environment (not healthy).

2. **Evaluate Option 1: Introducing Biogas Plants**:
- Biogas plants use animal and plant waste to produce methane and carbon dioxide, which are used as fuel.
- This practice is environmentally friendly as it utilizes natural waste and reduces pollution.
- **Conclusion**: This option is healthy for the environment, so it is not the answer.

3. **Evaluate Option 2: Using Natural Pesticides such as Neem Oil**:
- Natural pesticides like neem oil are derived from plants and do not harm the environment.
- They help in pest control without introducing harmful chemicals.
- **Conclusion**: This option is also healthy for the environment, so it is not the answer.

4. **Evaluate Option 3: Drip Irrigation**:
- Drip irrigation is an efficient method that delivers water directly to the plant roots, minimizing water waste.
- This method conserves water and helps maintain the water table.
- **Conclusion**: This option is good for the environment, so it is not the answer.

5. **Evaluate Option 4: Using Artificial Fertilizers**:
- Artificial fertilizers can increase crop yield and profitability.
- However, they can deplete the soil of its natural nutrients and lead to groundwater pollution.
- The chemicals from these fertilizers can leach into the groundwater, making it unsafe for consumption.
- **Conclusion**: This option is profitable but harmful to the environment, making it the correct answer.

### Final Answer:
The correct answer is **Using artificial fertilizers**.
