Artificial Island, good or bad?

Hello pekau, greetings. I have no idea of how secure an artificially built island would be. It seems it would sink in earthquake prone places, but one must take into account what modern technology can do. I understand that in Japan they have for a long time been extending their coastline by dumping recycled waste into shallow bays and so far without disaster. 

Of course I (and most others) would love to see proof of the existence of an Atlantis, a lost civilization that ruled the world way back in the mists of time, but certain global realities need to be taken into consideration. I favor the island of Thera as a possible location, but then the whole of the Mediterranean is a geologically unstable area. There are recorded instances of islands that rise and fall.

I imagine artificial islands are about as good for the environment of the sea as urban sprawl is for the land.

You're just utterly destroying a big chunk of the wilderness, of course it is bad for the environment. Picture a 10 square mile bushlot. Now picture someone builds a 10 square mile concrete block, a few hundred feet high, there. Was it good for the bushlot?

O, spare us great master of evil! But shouldn't that be ten billion yen?

Well yeah, havn't you seen the Austin Powers movies 

Shangra La, where i shall spent my ten million yen on booze and computer games, oh, and dancing girls, and maybe some sharks.

Artifical Islands?

Almost every city in Europe, with either access to the seas or located alongside of rivers, was converted into aritifical islands at one time or another as a defensive measure. France in general, and Paris in particular, are both called "Isle(s)!" Any where canals were dug to make a moat, there was created an island! Examples probably number in the thousands or tens of thousands world wide?
