Into the Zoo, Out from Utopia

In a world where a human volunteer, smart, yet bold and lacking common sense, journeys into multi-parallel universes in order to save his nation and kind from extinction, takes an unexpected turn of events and enters a different, exotic world where various anthropomorphic animal species populate "their" Earth. He encounters new challenges everywhere he goes, and only relies on the technology and resources he has to carve through those challenges, and also making allies, while figuring out how to get back home. Yet, more difficulties lie before him in a hostile world where its inhabitants query and enmity the lone visitor, as fear of the unknown consumes the inhabitants. Of course, one problem eventually leads to a catch-22, and different worlds with different cultures, different civilization, different morals, different "species" collide for the worst.
