Due to small area to search for food and limited prey availability makes species living on remote islands more prone to to go extinct over time.
Thankfully, Island conservation is an organization which is trying hard to conserve species which are struggling. They are getting huge success. They prevents extinctions by removing invasive species from islands. To date, they have successfully restored 63 islands worldwide, benefiting 1173 populations of 468 species and subspecies.
Working together with local communities, government management agencies, and conservation organizations, they select islands that have the greatest potential for preventing the extinction of globally threatened species.
