低碳生活的英语演讲稿 I am honored to stand here to share with you on such a important subject as climate change.Yes ,it is global warming . Let me give you two phenomenons. Here is the first one. More and more people used to be using air condition ，but how many people ever thought whether this new ?hobby? will bring side-effects or not? Maybe just few people.

Who pays for it ? First,as the pace of human high-tech development process goes quiker and quiker, the side-effects with the science development reflected, global warming is one examp
