It's 2030. Advanced science made it possible for humans to change appearance in different ways depending on wealth and environment. For example in poor countries there is low accessibility to the new technologies. Meanwhile in well developed and rich countries scientists and politicians incorporated new systems to research the new possibilities. For example some schools have additional transformation classes for the students to see firsthand how the technology works transforming them into animals and teaching them their anatomy. A few countries even incorporated the technology into their military transforming their soldiers into animals or hybrids for better efficiency. There are even special institutions that let you experience how it would be to live as an animal with bigger or lesser consciousness. The possibilities were endless.
