Earth has been able to support life because its position relative to the Sun provided it with enough heat, but not too much heat for early bacteria to evolve.

地球之所以能够维持生命，是因为它相对于太阳的位置为它提供了足够的热量，但热量没有多到可以让早期的细菌进化。

But that may not matter too much. Lasers are more efficient than xenon lamps, which waste a lot of energy as heat.

不过瑕不掩瑜，激光的效率比氙气灯高，因为后者的能量很多以热能的形式散失了。

But they are not taking care of the earth very well. They are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space.

但是它们对地球却不怎么在意，它们把太多的二氧化碳释放到大气层中，这就阻碍了热量从地球上散发到太空中去。
