Scientists have calculated how many mammals might be lost this century, based on fossil evidence of past extinctions. Their predictions suggest at least 550 species will follow in the footsteps of the mammoth and sabre-toothed cat. With every ”lost species” we lose part of the Earth’s natural history, they say. Yet, despite these ”grim” projections, we can save hundreds of species by stepping up conservation efforts. The new research, published in the journal Science Advances, suggests that humans are almost entirely responsible for extinctions of mammals in past decades.
Despite this ”alarming” scenario, we could save hundreds if not thousands of species with more targeted and efficient conservation strategies, said Tobias Andermann of the Gothenburg Global Biodiversity Centre and the University of Gothenburg. In order to achieve this, we must increase our collective awareness about the ”looming escalation of the biodiversity crisis, and take action in combatting this global emergency”. ”Time is pressing,” he said. ”With every lost species, we irreversibly lose a unique portion of Earth’s natural history.”
According to these models, the extinctions that have occurred in past centuries only represent the tip of the iceberg, compared with the looming extinctions of the next decades. ”Reconstructing our past impacts on biodiversity is essential to understand why some species and ecosystems have been particularly vulnerable to human activities – which can hopefully allow us to develop more effective conservation actions to combat extinction,” said Prof Samuel Turvey of ZSL (Zoological Society of London).
