Scientists Issue Strong Warning on Threats to Earth’s Ecosystem

15,000 scientists have issued a dire warning about the precarious state of Earth’s ecosystem, stressing that humankind must act immediately to try to reverse the effects of climate change. The risks of inaction, they say, are massive and include deforestation, species extinction, declines in freshwater availability, collapsing marine fisheries, and overpopulation. Representing 184 countries, the call to arms from the Alliance of World Scientists was recently published in the journal Bioscience. The article stated that “we have unleashed a mass extinction event, the sixth in roughly 540 million years, wherein many current life forms could be annihilated or at least committed to extinction by the end of this century.” —TV
