Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.
The conclusion that can be made given this information is that ants count their steps while walking.
And given that their legs were not either shorter or longer, that means their steps were either shorter or longer, which means that made either fewer or more steps then in the beginning. And if you take into consideration that they counted, let's say, 20 steps, and then either didn't get to their initial position or passed it, the answer is obvious.
