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, artificial and/or islands:
“For my own part, I commonly attend more to nature than to man, but any affecting human event may blind our eyes to natural objects. I was so absorbed in him as to be surprised whenever I detected the routine of the natural world surviving still, or met persons going about their affairs indifferent.”
—Henry David Thoreau (1817–1862)
“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)
“The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.”
—W.E.B. (William Edward Burghardt)
