Wood is one of the resources in Empire Earth. It is harvested by citizen by felling trees. As with all other resources, the supply of wood is ample, but not endless. Unlike the very high stockpiles of mines and farms, single trees usually contain 500 units of wood and especially on island games, wood supply can run out as trees do not grow back.
Tactical Use Edit
On maps that have water and fishing spots, wood can be vital for an economic concept called "wood for food". To collect food using citizen, one has to invest food to create harvesters. If wood supply is ample, one can build fishing boats instead, which cost wood instead of food. This way food can be spent on citizen to harvest other resources. This helps building up an economy in the early stages of a game.
Due to the absence of docks, this method cannot be applied in the Prehistoric Age
