let me explain to you

1. 杰克的腿残疾了,他只能坐轮椅,可是当时的科技已经能克隆外星人身体了,却不能治好他的腿,生物克隆技术可是比器官移植技术难多了啊.

It is not the technology, it is money. In the beginning it was explained that the whole reason Jack (and other soldiers) went to Pandora was for money ("not for fighting for freedom" as it was said). Jack traded his service for getting his legs fixed ("the Company" will pay for that).Like right now traveling into the space is feasible but I can not afford that. The price tag is $20,000,000 for a 20 minute ride.

2.潘多拉星球上氧气不多,二氧化碳多,人在上面必须戴氧气罩,可是战斗的时候,那个火烧得够旺啊,如果二氧化碳含量高,氧气少,那个火没有可能那么烧的.

On earth, carbon dioxide level in atmosphere is 380ppm (0.038%). When it raises to 5%, it will have devastating effect on breathing (leads to hyperventilation). However, 5% carbon dioxide can easily support burning (assume oxygen level remains the same as earth, that is 21%).

So in summary there is no science problem.

It is great to raise questions.
