The ecosystems we see around us used to be filled with species such as lions, elephants, cheetahs, and camels. These were all normal residents of North America at one time. To scientists, they are referred to as extant, meaning that they did not die out completely, extinct, they only died out in a specific area. What if we could restore these extant animals to where they once lived? Is it a good idea and how would that change our relationship with nature?
