British born artist, Jason de Caires Taylor's La Evolución Silenciosa (The Silent Evolution) is simply breathtaking... not least because it is 9 metres below sea level! The famed environmental artist and scuba fanatic's response to the overuse of Cancun's delicate reef systems by the 750,000 annual visitors was to draw some away to a new artificial reef comprised of some 400 human body casts. Eerie, unnervingly still, but no less beautiful.  An assembly of real Mexican locals molded from environmentally sensitive concrete with low pH to encourage coral growth and attract marine life to an area otherwise uninhabited by sea flora and fauna.
