This system costs farmers money because of the increased handling time and lost margins when tags do not match in the system resulting in lower payments to farmers. New Zealand is planning a similar National Animal Identification and Tracing system. National Animal
Animal communication teaching these animals a gestural (human made) American Sign Language-like language, the animals have been found to use the new signs on their own to get what they need. The recent experiments on animal language are perhaps the most sophisticated attempt yet to establish human/animal communication, though their relation to natural animal communication is uncertain. The importance of communication is evident from the highly elaborate morphology, behaviour and physiology that some animals have evolved to facilitate this. These include some of the most striking structures in the animal kingdom, such as the peacock's tail, the antlers of a stag and
