The ravages of guns, nets and bulldozers

[...]unless the species being assessed is long-lived (with an expected lifespan of 30-50 years, say), projections cover a period during which the effects of climate change, in particular, will be relatively modest. Yet we do not think that any of these caveats alter the overall message. Because agricultural activity and overexploitation tend to occur in fertile places with naturally high levels of biodiversity4, the patterns emerging from our analysis probably extend to many of the other species that have not yet been assessed.
