  • It depends how big a rock you need to be to count it as an island. Unless you mean very small indeed, there are no uncharted islands: satellite based cameras can see all rocks and island -ike things more than a few feet across, and those more than a few tens of feet across will be charted - though not necessarily on easily-available maps. But there are many millions of undiscovered species of flora and fauna; tens of thousands of new species are classified every year. Islands are a particularly suitable place to search for new species, because many islends have been separated from other land masses for quite a long time and evolved their own species. Many of the species discovered every year would be regarded by many people as "boring" - an awful lot of them are new kinds of beetles. But to those studying the diversity of life, every beetle is valuable.
  • A great many islands have been discovered, charted, and lost. We guess they sank back into the ocean, since new ones pop up where we knew they didn't previously exist. There are some really big islands rising slowly, such as the new Hawaiian island that is still under water. And there are plenty of corners of continents where no man has ever been known to visit, mostly in S. E. Asia and South America.
