Researches have put an average price tag of US $ 33 trillion a year, on the fundamental ecosystems services, which are largely taken for granted because they are free. This is nearly how many times the value of the global gross national product (global GNP)?

Options

A. Two times
B. Three times
C. Four times
D. Five times

Answer

To solve the question regarding the average price tag of ecosystem services and its relation to the global gross national product (GNP), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Values Given**:
- The average price tag of ecosystem services is US $33 trillion.
- The value of the global gross national product (GNP) is US $18 trillion.

2. **Set Up the Calculation**:
- To find out how many times the value of the GNP is contained within the value of the ecosystem services, we will divide the value of ecosystem services by the value of GNP.

3. **Perform the Division**:
- Calculation:
\[ \text{Number of times} = \frac{\text{Value of Ecosystem Services}}{\text{Value of GNP}} = \frac{33 \text{ trillion}}{18 \text{ trillion}} \]

4. **Simplify the Calculation**:
- This simplifies to:
\[ \frac{33}{18} \approx 1.8333 \]

5. **Interpret the Result**:
- The result indicates that the value of ecosystem services is approximately 1.83 times the value of the global GNP.

6. **Round the Answer**:
- For practical purposes, we can round this to 2 times.

### Final Answer:
The average price tag of US $33 trillion a year on ecosystem services is nearly **2 times** the value of the global gross national product (GNP).
