The price of bringing something to Mars that could terraform it would cost billions, possibly even trillions.
将火星地球化的材料带到火星就得花费上数十亿,甚至几万亿的钞票了。
Of course this in itself would take millions of years, at the present there seems no way to terraform Mars and no reason to.
当然这样一个过程得用上成千上万年。 在如今,似乎没有很好的方法和理由来使火星地球化。
