Woolly Mammoth Revival: Ecological Claims Questioned

Colossal's ambitious plan to resurrect woolly mammoths rests on claims of their positive ecological impact, particularly on carbon sequestration. However, existing research on the effects of large herbivores on carbon sequestration is mixed: African forest elephants may enhance it, while savanna elephants reduce it. While one study suggests increasing large herbivore populations lowers permafrost temperatures, the feasibility and cost-effectiveness are questionable. Furthermore, warmer winters due to climate change could mean mammoth trampling accelerates soil warming. Ecosystems are complex and unpredictable, making it challenging to assess extinct species' impact on modern ecosystems. Colossal's narrative leverages this uncertainty, but this doesn't make their claims more likely to be true.
