If we strategically expand protected areas on Earth just 5% and focus on birds and mammals with a more diverse evolutionary history, the range of species and places that can be preserved would be triple that of current conservation efforts, a new study in Nature finds.

The context: Scientists have warned for years that iconic species like giraffes, mountain gorillas, African elephants and rhinos are under assault from a combination of land use, poaching and climate impacts, and face extinction in the wild in the next 20 years.
