I enjoyed reading the article. It shows that nature can be unpredictable -fencing off the trees did not benefit their growth. The relationship between the acacia trees and a group of ants and how they help each other to thrive is interesting. It's another reason to marvel at nature.

The article was very informative and provides yet another instance of the complexity underlying nature. Same kind of effects are seen when species from other biome is artificially introduced by humans. In short, for humans, What goes around, comes around.
