We can see from the opening cutscene that it brings rain to Mars and plant life to Venus. It also gave individuals power, i.e. the Awoken and Warlocks. The Ghosts were it's final act, in order to give guidance to the Guardians who would take up the Traveler's mantle.

If you've ever played the PC game Spore, you know how terraforming works. For those who don't know, it's the process of adding elements to a planet to make it livable. Rain being an example, but also plant life and atmosphere. A tactic I picked up in Spore is that terraforming works both ways. I used to buy terraforming materials, (which were cheaper than bombs and such) and seed an enemy planet with machines. The devices would activate and kill everyone on the planet by driving the atmosphere to an extreme, then I would swoop in and terraform it back to normal. A long and arduous process, much like my sidebar.

The reason I mention Spore, is because I believe that the Vex (the villians) are trying to use the Traveler for that exact purpose. I'm taking a stab in the dark here, but I will assume that the Vex want to destroy all life in the universe. Using the Traveler to negatively terraform would be a devastating weapon, especially if they can manipulate time, even partually. The Traveler would be a perfect weapon. I think it mostly sounds reasonable.
