Natural Vs Artificial Islands
Most of the Earth's islands are natural and have been formed by tectonic forces or volcanic eruptions. However, there are also artificial or man-made islands. An example of an artificial island is an island in Osaka Bay off the Japanese island of Honshu, on which Kansai International Airport is located. Artificial islands can be built using natural materials (e.g. dirt, sand, rock) and/or artificial ones (e.g. recycled waste, concrete slabs). Sometimes natural islands are artificially enlarged. An example is Vasilyevsky Island in the Russian city of St.Petersburg, which had its western shore extended westward by some 0.5 km due to the construction of a new sea terminal.

Famous quotes containing the words natural and/or artificial:
“My darling girl, Unfortunately this earth is not ... a fairy- land, but a struggle for life, perfectly natural and therefore extremely harsh. All the same, or precisely for this reason, it is happiness and comfort for us men to have a precious sweetheart—and I have the most precious, the dearest and best of all!”
—Martin Bormann (1900–1945)
“Before I finally went into winter quarters in November, I used to resort to the north- east side of Walden, which the sun, reflected from the pitch pine woods and the stony shore, made the fireside of the pond; it is so much pleasanter and wholesomer to be warmed by the sun while you can be, than by an artificial fire. I thus warmed myself by the still glowing embers which the summer, like a departed hunter, had left.”
—Henry David Thoreau (1817–1862)
