Islands make up only about 3% of the earth's land area but host about 20% of all species and 50 to 60% of endangered species. The biggest threat to islands are invasive species, mainly rats, but also pigs and cats, who feed on nesting birds and native plants. New Zealand has been the innovator in clearing islands of rats because of its endangered populations of flightless birds which are vulnerable. One species of flightless parrot, known as the kakapo, has only 131 individuals left in the "wild" - they are closely guarded 24x7 on Codfish Island, their nests surrounded by rat traps and cameras vigilantly on the lookout for invaders.

In 2000, the Spanish Pyrenean Ibex (a type of mountain goat) went extinct. In early 2009 it was brought back to life, the first time an extinct species has been "successfully" cloned. The newborn bucardo died of respiratory failure minutes after birth, setting a second extinction record.
