SAT Reading: Cross-Text Connections on De-extinction and Permafrost Preservation
A Digital SAT-style paired passage exploring two contrasting perspectives on using bioengineering and proxy megafauna to prevent permafrost thaw in subarctic biomes.

Ecologists desiring to recreate long-vanished beasts affirm that positioning proxy animals in frigid subarctic latitudes could decelerate thaw. During frosty spans, heavy herbivores stamp down fluffy snowpacks, compacting the porous insulating layer so icy gusts penetrate deeper permafrost strata. This cooling operation impedes decay in buried organic residue and lowers gas expulsion. In turn, bioengineering presents a viable approach to counter ecological devastation.

Although reviving prehistoric beasts holds promise, leaning upon proxy animals to chill tundra ground neglects momentous ecological realities. Subarctic biomes have shifted over millennia, whereby newly inserted fauna might unintentionally disrupt extant wild trophic networks. Beyond this, channeling massive monetary treasuries into bioengineering drains resources away from shielding present-day imperiled biomes. Conservation frameworks ought to give precedence to shielding extant ecosystems rather than testing unproven biological conjectures.
