Minecraft wiki entry for Adventure_survival, associated text: One extremely useful tactic is to get creepers to blow up a house or farm in a village; this way, you can get wood and cobblestone. Wheat can be used to breed animals or crafted into bread, though seeds cannot be replanted. Trampling is a more efficient way as you will not lose any of the wheat, however, melon farms in savanna and desert villages and pumpkin farms in taiga and snowy taiga are useless due to trampling stem drop seeds while pumpkins and melon are unbreakable. since you cannot place or destroy blocks in adventure mode; only blocks that are used in crafting or for trading can be useful).
