A good wood burning camping stove will utilize less wood than just cooking over a campfire. It is more efficient, and a bit easier to use a small cooking pot. They are not bad, and are easily built. There are a few techniques which can give you the same effect without carrying anything, such as a prairie stove where you dig a small hole, with a tunnel for air and build the fire in the hole with your pot over the top. It is dangerous in some forests though, with so much rotting vegetation instead of sand or dirt. You run the risk of starting a fire without knowing it.
