如果地球沒有光存在的話, 會對人類帶來甚麼整體的影響?

沒有光的地球,首先理解為單純失去了太陽的照射,那地球表面溫度會急劇下降,植物沒法進行光合作用,也就是說,沒法再生產食物,沒法將二氧化碳轉為氧,理論上人是會滅亡,而星球也跟著死亡,又或者一種新的生物(非由人進化)取而代之成為地球的主宰.

但,也有一種可能性是,一段時間地球會處於假死狀態,之後,存活下來的人會進化,變為可以在新的環境下生活的生物,

而事實就是,失去太陽光,就是說太陽已滅亡,那時候,太陽會把地球吞噬,所以,人類與地球是會一同死去...

這個題目應該是生物學,環境學或天文學的,絕不會是物理學,

all life on earth have their life/chemistry base on light. If there is no light on earth, if life is going to start on earth, our chemistry may not be base on carbon. very likely that there will be no intelligent on earth ...

if there is no light on earth now, temperature will drop to -250?


with our current technology, a small group of us can probably last a while (provide they have basic resource like food), but only a while, may be a few years, when our energy ran out, which will be soon, we will die. Even if we found way to generate enough energy in a sustainable way, the most important of light to us is the aid of photosynthesis, when the plant uses sunlight and convert carbon dioxide back to oxygen, this is probably the only way that we can efficiently and effectively to have our oxygen recycle. if there is no light, when we use up our oxygen, that's the end for human.

if there is no light now, a small group of human will last a couple of years, after the last one die, earth will be lifeless!

hope that will not happen....
