The North American Ground Sloths: A Conservation Success Story

Scenario: In the early half of the 20th century, thanks to the groundbreaking work of innovative and daring scientists, a form of time travel was accidentally discovered during the course of experiments with the recently discovered field of quantum physics. The years that followed saw the construction of the world's first time machine, a structure that was equal parts high-concept science and industrial might, built in a remote part of southwestern United States. At first, the time machine was merely used for exploratory purposes, delving into both the past and potential futures to gather knowledge previously beyond human reach. However, as the reality of the power humanity now possessed began to sink in, along with the increasing cases of extinction, the scientists and the government began to look at further potential uses for the time machine. Considering the pace of extinction of many animal species in North America due to human impact, ambitious and forward-thinking conservationists within the government proposed a radical plan: to turn back time in a very literal sense by reintroducing extinct species back into their former habitats. After a long series of debate and trial runs, they settled on a number of extinct ground sloth species. These species included the Shasta ground sloth, reintroduced into the subtropical forests that were its native habitat in the southwestern and south-central parts of North America, the Jefferson's ground sloth, reintroduced in the colder temperate and boreal habitats of northeastern and midwestern North America as well as higher, colder areas in the South, and the Harlan's ground sloth, reintroduced in both temperate and some hotter subtropical open habitats in midwestern and southwestern North America. Further south, the Mexican glyptodont, a large armadillo-like animal that once roamed the tropical and some subtropical forested and open habitats of southeastern North America and Central America, was also brought back to life. The reintroduction was a careful process, involving habitat compatibility checks, trial reintroductions, and long-term tracking. Scientists managed to ensure each species was reintroduced into environments that suited their specific needs, and free from time paradoxes. The populations managed to establish themselves and begin to grow, their presence adding to the biodiversity of the continental landscapes once more. In our hypothetical world, this radical plan to turn back time and revive extinct species revived not only the ecosystems and biodiversity, but also triggered an ecology-based social revolution. With extinct creatures strolling among them, people across the globe started looking at nature and their environment with newfound respect and interest: a reawakening of the connection between human and nature. Conservation became a universal value, and the world began to take significant steps towards reversing the damage done by centuries of industrialization and habitat destruction. Thus, the reestablishment of the ground sloth population in North America through the use of time travel marked a significant point in our hypothetical 20th century, breathing new life, literally and metaphorically, into the continent's natural heritage.
