摘要：As long as human activity requires much energy, a large amount of CO2is produced. The World Meteorological Organization announced that in 2016 the CO2concentrations in atmosphere reached a new record. This is the highest growth in the last 30 years, based on measurements performed in 51 countries. The growth concentration is with 50% higher than the mean level of the last 10 years. The level of the CO2in the atmosphere is 100 times higher than at the end of the glacial era. This can cause unexpected changes of the climate and also severe destructions of the economic system. Even if researchers believe that the raised level of CO2is not responsible for the rise of the temperature on the globe, we agree that the initiative to diminish the CO2level in the atmosphere is a useful one. We propose the possibility to deposit an amount of liquid CO2in a deep pit near Greece as an example of what can be done to protect the environment. We solved at the beginning the problem using an integral calculus to estimate the liquid CO2flow rate. Then we calculated the time in which a pit can collect what is sent at the bottom of the Mediterranean Sea.
