摘要翻译:
达尔文理论将生命描述为在敌对环境中为生存而战所压倒的消耗。然而,从热力学的角度来看,生命是一个动态的、不平衡的过程,与它的非生物环境协同稳定和共同进化。生物圈中最大的生物组成部分,植物和蓝藻,参与了大量水的蒸腾。蒸腾作用是全球水循环的一部分,正是这个循环使地球与其貌不扬的生命贫瘠的邻近行星--金星和火星--区别开来。水循环,包括生物圈对阳光的吸收,是地球上最大的熵产生过程。因此,从这个角度来看,生命可以被视为执行一个重要的热力学功能;通过帮助诸如水循环、飓风、海洋和风流等过程产生熵来充当动态催化剂。在这种观点中,动物的角色是植物和蓝藻的不知情但专注的仆人,帮助它们生长并传播到最初不适宜居住的地区。

英文摘要:
Darwinian Theory depicts life as being overwhelmingly consumed by a fight for survival in a hostile environment. However, from a thermodynamic perspective, life is a dynamic, out of equilibrium process, stabilizing and coevolving in concert with its abiotic environment. The living component of the biosphere of greatest mass, the plants and cyanobacteria, are involved in the transpiration of vast amounts of water. Transpiration is part of the global water cycle, and it is this cycle that distinguishes Earth from its apparently life barren neighboring planets, Venus and Mars. The water cycle, including the absorption of sunlight in the biosphere, is by far the greatest entropy producing process occurring on Earth. Life, from this perspective, can therefore be viewed as performing an important thermodynamic function; acting as a dynamic catalyst by aiding process such as the water cycle, hurricanes, and ocean and wind currents to produce entropy. The role of animals in this view is that of unwitting but dedicated servants of the plants and cyanobacteria, helping them to grow and to spread into initially inhospitable areas.
