How is extinction changing the world around us?

No one knows exactly how many plants and animals are vanishing from the world around us, but a rough estimate is that we lose one species every hour. Humans have never witnessed an extinction event like the one we’re living through right now – one that's wiping out wildlife all around us, from birds to bears, plants and insects. Tierra Curry lays out the extinction crisis, what’s been lost, how wildlife declines affect us in ways we don’t notice and what can be done.
