lol really?!
I took one tree down and it dropped a sapling, took that one and got another tree and it just multiplied from there on, dug some where there is a hole on the first island to get some coal and stuff; and by the time I had like 5 trees I made a house, dug up some sand and made glass, then finally made a boat.
to survive at first with food I took a hoe to some long grass and planted some wheat and made bread
