As there is only 0.03% of `CO_(2)` in the atomsphere and when the green plants on the earth use `CO_(2)` every year there is danger of scarcity of `CO_(2)` in

Options

A. 100 years
B. about 1000 years
C. after 3000 years
D. no danger at all

Answer

### Step-by-Step Solution:

1. **Understanding the Current CO2 Levels**: The atmosphere contains approximately 0.03% carbon dioxide (CO2). This percentage is relatively low compared to other gases like nitrogen and oxygen, which make up the majority of the atmosphere.

2. **Role of Plants in CO2 Utilization**: Green plants utilize CO2 during the process of photosynthesis. They absorb CO2 from the atmosphere to produce glucose and oxygen, which are essential for their growth and energy.

3. **Annual CO2 Consumption by Plants**: While plants do consume CO2, the amount they use is a small fraction of the total atmospheric CO2. Given the vast volume of the atmosphere, the total amount of CO2 available is still significant.

4. **Natural CO2 Production**: CO2 is continuously produced through various natural processes, including respiration by animals, decomposition of organic matter, and volcanic eruptions. These processes help replenish CO2 levels in the atmosphere.

5. **Carbon Cycle**: The carbon cycle is a natural process that maintains the balance of carbon in the environment. It involves the movement of carbon among the atmosphere, oceans, soil, and living organisms. This cycle ensures that CO2 levels remain stable over time.

6. **Conclusion**: Given the continuous production of CO2 through natural processes and the vastness of the atmosphere, there is no imminent danger of CO2 scarcity despite its low concentration. Therefore, the concern about CO2 depletion due to plant consumption is unfounded.

### Final Answer:
There is no danger of CO2 scarcity as it is continuously replenished through natural processes and the vast amount present in the atmosphere.
