In memory of species declared extinct in 2018 — plus one we’ve already lost in 2019

Earth is losing wildlife at an alarming pace, a crisis many scientists now describe as a mass extinction event.

Wild plants and animals are vanishing amid a storm of human-induced disasters, namely habitat loss, unsustainable hunting, invasive species, pollution and climate change.
