Actually,given the movie's lenght,there are a ton of posibilities to choose from But the top ones for me would be: Quaritch bombing the soultree and/or hometree RIGHT after they got the location from Jake. Alternatively when at the end of the movie the humans board the transport ship they could literally make a u turn in space and bomb the soultree with rocks (which thrown from orbit would nearly have the power of a nuclear impact according to Physics or so my fuzzy memory recalls) ºJake happily going offworld after Quaritch tells him he got the paperwork for his spine operation. I would also add the fact thatJake also made use of his stay at hometree and takes home to earth a couple of unobtanium rocks scrapped from the roots and lives the large life.Back in Pandora,the na'vi all cry hugging trees while being gleefully exterminated by the colones and the space marines. Also,sigourney weaver gets fired ºThe RDA company finds a new market for avatars,taking commissions and selling them to Furries ºThe company and/or the space marines do some history research and screw up the planet's ecology by introducing a foreign animal species (I vote Beaver or pigeons). I know what you ll say about this one : "Earth creatures can't breathe the pandoran air" To which I would reply that the company realizes that instead of spending shitloads of cash in RC human thundercat hybrids they could use a fraction of the time and money to quickly engineer a beaver or Koala or Grey Rat in order to make it survive the moon's atmosphere
