It all made sense, except for one tiny problem: this same model also suggested that a little world like Earth shouldn't exist at all; it (or more precisely, the moon-size proto-planets that eventually assembled into Earth) should have spiraled into the sun more than 4 billion years ago.

这种说法基本上讲得通，除了有一点点小问题：这样的模型也说明像地球这么大的小行星根本就无法存在，它（或者更精确点说，加上月球那部分合并成的地球）应该在40多亿年前就呈螺线坠入太阳。

Be it good growth or bad growth, any unbridle growth creates huge imbalance in the earth ecosystem, simply working to sustain the monoculture of human temporarily.

因此，不管是作者提倡所谓比较环保的「好」成长，或是当前人类不永续的成长模式，只要是无限制的成长，都会让地球生态系统中人类与其他物种以及环境间的关系越来越不平等，只会让地球成为以人类为主的单一文化，人类的成长也许暂时能够持续，但没有其他多样物种和环境的支持，人类所谓的「永续」只是暂时的，追求无限制的工业成长是短视近利的。
