根据维基百科”,所有已知类型的生物能够一定程度的对刺激的回应,繁殖,生长和发育和通过体内平衡自律。”Further, watching a video like the "地球呼吸随着季节的变化”(这是来自美国宇航局)——表面上给了“地球是有生命的”的感觉。

地球的历史可能表明它能够成长和发展。Climate change, I would think shows Earth "responds to stimuli" - and that it is able to "self-regulation" conditions to remain stable and relatively constant. [Unable to define what reproduction might be. That said, I do belief that it might be possible (in theory) to define an observable phenomena as being reproductive.] Lastly, think most of Earth Science would agree that at some point "Earth will die" so to speak.

地球是一个生物吗?请注意,你的答案必须涵盖即使理论上地球是如何“能够一定程度的对刺激的回应,繁殖,生长和发育和通过体内平衡自律。”

更新:

• 被动态、活动等并不意味着一个实体是一个有机体:例如,晶体不是生物。
• 如果地球不繁殖,它不是一个有机体。在我看来,没有必要对盖亚假说发表任何评论或回答,因为它并没有回答这个问题;这意味着盖亚假说并不宣称地球是一个生物体。
