人类在这个星球上的活动规模导致了温室气体排放和与之相关的大气酸化问题。几个世纪以来,通过对特定技术的开发,我们完成了向更舒适和更灵活生活方式的转变。但是,基于全球经济的现实,人们尚未发现或开发出任何改变使用碳基能源并释放数十亿吨二氧化碳和其它温室气体的农业和工业体系。和工业化时代开始时的280ppm相比,目前大气中的二氧化碳排放量已经达到392ppm。如果加上所有其他温室气体,其浓度可能高达425ppm,逼近450ppm的危险值。一些科学家已经 The scale of human activity on this planet has led to the issue of greenhouse gas emissions and the associated atmospheric acidification. For centuries, through the development of specific technologies, we have completed the transition to more comfortable and flexible lifestyles. However, based on the reality of the global economy, no agricultural or industrial system has been discovered or developed to change the use of carbon-based energy and release billions of tons of carbon dioxide and other greenhouse gases. Compared with 280ppm at the beginning of the industrialized era, the current atmospheric carbon dioxide emissions have reached 392ppm. If you add all other greenhouse gases, the concentration may reach 425ppm, approaching the dangerous value of 450ppm. Some scientists already
