Recently, Chinese Academy of Science started researching on "the change of land utilization and ecology system carbonization". In the next 3 years, over 100 researchers will join the research project with an investment of RMB20 million.

Professor Li tells the reporter that this research aims to study the CO₂ absorption and emission of forest, prairie, and farmland. And re-arrangement of land utilization will better absorb the excessive CO₂ from fuel consumption.

Since the industrial revolution in 1850s, the concentration of CO₂ in the air increased dramatically. CO₂ has caused green house effect and a series of natural disasters. The sources of the excessive CO₂ are still unknown. The research on carbon is an important topic in the 21st centaury.
