Wasteland is first planet's biome, it is non-habitable and player cannot place any useful resources in the Wasteland. The player can only use Ocean Giant to place ocean (that give him possibility to place swamps and forests) or to use Rock Giant to place Mountain. (that will start automatic creation of desert/s)
The only way Wasteland can be made by the player is by removing a Mountain using the Ocean Giant's "Create Ocean" ability or removing an Ocean using the Rock Giant's "Create Mountain" ability. However, there is no reason for the player to create Wasteland, seeing as nothing useful can be done with it.
