Ⅲ. Theoretical analysis of the waste problems
We can approach to the analysis of problems to be solved at both a micro and macro level. What we will deal with is the environmental problems taking place all over China, which are characterized by a mix of pervasive influences and a number of factors. It follows that it is more appropriate to take a macro approach which enables us to see problems

Ⅰ. 서 론
축축하게 젖은 땅, 늪 혹은 습지는 말없이 생겨나고 사라지면서 인류에게 생태와 환경에 대한 메시지를 조용히 전한다. 지구 안 또 하나의 작은 생태계라 할 수 있는 습지는 먹이사슬이 잘 유지되어 다양한 생물종이 모여 사는 지구의 허파이자 자연의 콩팥이다. 습지는 인류 역사에서 중대
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
Coalbed methane is a form of natural gas that is trapped within coal seams.
In recent decades it has become an important source of energy in United States, Canada, and other countries.
It is called sweet gas.
Enhanced coal bed methane recovery
is a method of producing additional coalbed methane from source rock.
This technique may be used in conjunction with carbon capture
