I've heard that you went down south. I joined the group who explored the tropical jungle. Well, we traveled into the rain forest. We found very few small trees.
Trees are tall and straight.
There are few branches near the ground, but many near the tops of the trees. So sunlight doesn't often reach the forest floor, I guess. No, there weren't many large animals roaming around, because it is difficult for them to find food. Yes, but very few. It's very hard for people to live in such a forest.
