This classification of risk means that the species is at serious risk of extinction.

• threatened

• vulnerable

• endangered

• extinct

The status of a "threatened species" means:

• they are almost extinct

• they are likely to become endangered

• they are extinct

• their numbers are increasing

Why are hotspots seen as being so critical to global biodiversity?

• because an exceptional percentage of earth's plant and animal species live in these locations.
• because the plants and animal species that live in these places cannot be found nowhere else in the world.
• both of these are reasons why hotspots must be protected and preserved
• neither of these are reasons why hotspots are critical to protect and preserve
