I've always thought that not only can we communicate with animals, we can work together with them. They do have extensive instinctive knowledge of their environments, and I have a fantasy of sorts that it is possible to tame a swamp, and work together with animals to make such an environment an agricultural powerhouse beyond what can be done in a field. It's far from only a commercial interest, however, because since animals do not fear one who has the face of a man (sins make you animalistic and make animals fear and want to attack you, shown by Shimson the prophet's fight with a bear) it will be a more moral and ethical society that can live in conjunction with nature.
The commercial interests of such an endeavor are vast, like monkeys picking a field of berries, birds trained to eat insects in specific areas, a number of creatures could plant and upkeep trees and whole gardens and other useful applications like we've taught dogs to do. If we can develop a relationship with a crocodile, there isn't any other creature in existence that we can't communicate with on a level, and ultimately work together with.
