1.Introduction
1.1 Introduction
In the recent years, environmental issues are getting more and more concerned by the public. One of the popular topics is the global warming. The environmental scientist indicated the incense of earth’s temperature might cause flooding and other climate changes, and the concentration of greenhouse gases are continuously increasing. Among all the greenhouse gases (GHGs), carbon dioxide is responsible for nearly 82%…
