As you can see, there is a major tree problem behind my house, where I plan to put my farm. Just a normal minecraft thing, there's a problem, you go and take care of it. So I climb to the top of the 20 trees, and as I'm bashing away leaves, suddenly
In my current survival world, there is a pig in a tree on the mainland near my base. If you take the rail line from my base to the village north of it, you'll encounter practically a whole dang forest of tree pigs. It's ridiculous.
