Nowadays more and more people are becoming concerned about the earth but many still do not realise we are consuming at a rate that the earth cannot cope with.We should learn about things we can do to treat the earth more gently.After taking the quiz,I have learned a lot about my ecological footprint on earth,and was surprised by this result.Because I frequently take the subway and bus,use many appliances at the same time,services have become the largest component of my ecological footprint.Therefore,I need to discover some practical ways to reduce the number.For example,by getting off the subway or bus one stop away from my destination,I could save some gas; by avoiding the use of multiple media,I can save a lot of energy; in order to save more energy,I will switch to use solar energy appliances.
中体来说写的很好,我的修改让整体感觉更通.可是想问问提早下地铁、公车为什么会省油?他们不照样要开嘛?这是个人看法.
