Island Environment
The islands in the atolls of the Maldives rest on the shelf provided by the reefs. Many reefs have no islands at all. But all islands in the Maldives have an underlying coralline reef. Usually islands are flat and sandy. Often there is a rocky bottom made up of a coral rock conglomerate underneath the island proper. Some islands are long and sandy while others have a rounder shape. The round islands often are lower in the centre, sometimes having a muddy or marshy spot.
Islands may disappear when the currents on the reef change. Maldivians call this phenomenon of erosion giramun dhiyun. New islands also may appear, beginning as sandbanks or coral gravel heaps at another location of the reef (a phenomenon that is known among Maldivians as vodemun dhiyun). Therefore, in the Maldives, islands are constantly eroding and constantly being formed. Human action, in the form of jetties or the dredging of channels on the reef, may change the pattern of currents on the reef and accelerate erosion.
The atolls in Maldives are often separated from each other by vast expanses of the deepest ocean; but despite the great distances, the daily life of Maldivians in the individual inhabited islands shows very few differences all along the length of the atoll chain.
Except for the capital, Malé (pop. 90,000), the environment in most islands is dominated by practically the same small number of ingredients: trees of a few types, low houses with small yards, the waterside always close at hand and almost no dramatic variations in the landscape. The Maldives has about 200 inhabited islands. The typical population is about 300 inhabitants per island, distributed in about fifty households.

Famous quotes containing the words island and/or environment:
“In all things I would have the island of a man inviolate. Let us sit apart as the gods, talking from peak to peak all round Olympus. No degree of affection need invade this religion.”
—Ralph Waldo Emerson (1803–1882)
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
