Wood

Wood are the first thing most miners and crafters would do. They are used to make wooden planks which leads to another bunch of things. (Wooden pickaxe, crafting table etc.) They can be punched down in 3 seconds more or less, and will be taken down faster with axes.

People also use wood as a building material too. It can be burned down by flint & steel and, can be blown up by explosive mobs. TNT should be avoided too.
