Minecraft wiki entry for Survival_in_an_infinite_desert, associated text: As of 1.14 there is another way to find a wood source without obtaining saplings or trees, which is via pillager outpost. Pillager outposts generated above ground consist of a huge amount of dark oak logs and the watchtower floor is made of birch planks. However, trying to tear down all the planks is a difficult challenge as the player with early equipment (or none) can easily be killed by the pillagers guarding the outpost. If the pillager outpost generates with a trapped iron golem, you can free the golem. While the golem fights with the pillagers, you can collect wood. If you are lucky to find a single outpost with two or more trapped golems, you have more time to collect wood as more iron golems can survive longer in the outpost before killed by pillagers (due to the fact that pillagers spawn infinitely in and around the outposts).
