Information about Biodiversity  

• Biodiversity hotspots
  The ultimate goal of this organization is to keep nature intact, which means stop anthropogenic species extinctions. To approach this goal, they try as much as possible to slow the rate of species extinction with whatever conservation resources they have at their disposal, which requires incorporating threats (or “vulnerability”) and costs into priority setting.
