That's right! Islands hold a disproportionately high number of the world's most threatened vertebrates - more than half of all critically endangered species. By focusing conservation efforts on islands, we can achieve the greatest impact for the least cost. In fact, studies have shown that investing just 10% of all conservation funding on islands could prevent over 62% of extinctions, while protecting 75% of the world's most threatened vertebrates. So yes, if you want to make a big difference in saving the planet's biodiversity, islands are the place to be!
