Guide:Renewability

Wood
Wood is arguably the most common and renewable resource. Chopping down a Tree frequently drops Acorns that can be planted to grow new trees. Wood is one of the most versatile resources as well, as it is used in both construction and crafting:


 * Wood can be used for both building structures and background walls.
 * Wood is used for creating Torches and Wood Platforms.

Sand
Sand is an infinite resource if you have patience or the equipment:


 * Antlions can be goaded into generating more sand, albeit very slowly.
 * A Sandgun used with ammunition-conserving equipment, such as the Necro Armor set, can produce infinite sand.
