Bad news for the planet’s tallest land creature was announced before the end of 2016: Giraffe populations are plunging in what scientists call a “silent extinction” due to poaching and habitat loss. (The extinction is “silent” because we had largely failed to notice their plummeting population.) Previously, the IUCN’s Red List had given them a “least concern” rating. News that their populations have dropped by as much as 40 percent since 1985 has caused their status to be changed to vulnerable.
