Sand.
Sand (also reffered to as "Earth" in-game) is an element in Ubisoft's game From Dust.
Sand is the only element on which plants may grow, provided there is a source of water nearby -- some maps require the player to pour water on the ground, meanwhile in other Territories the environment is damp enough for vegetation to grow over any sand available.
Sand Uses[]
Sand makes a good material for building bridge-paths and elevating ground in the short term, because it is usually a plentiful matter. However, in the long term, rock is generally better for those purposes because sand is eroded by moving water, such as tsunamis or rivers. Sand is also useful to be placed around villages which don't have protection from fire, as opposed to lava which can ignite plants and rapidly destroy entire villages.
