Two days ago it was the 40th Earth Day and we've already spoken about it here.
To celebrate it, The Big Picture, in my opinion one one of the best photoblog of the web, have prepared a gallery of 40 images,
"each a glimpse into some aspect of the world around us, how it affects and sustains us, and how we affect it."Just as I expected a half of them are strictly related to water and it's anything but a surprise given the key-role that H20 has in our planet...
Enjoy the pics, and check the original The Big Picture's gallery for all the others images.
This undated handout photo provided by the journal Science shows Iron oxides staining the snout of the Taylor Glacier, in the McMurdo Dry Valleys, Antarctica, forming a feature commonly referred to as Blood Falls. The iron originates from ancient subglacial brine that episodically discharges to the surface. Outflow collected at Blood Falls provides access to a unique subglacial ecosystem that harbors a microbial consortium which actively cycles iron, sulfur and carbon for growth.

Local miner Cesar Abac uses a wooden bowl and mercury to pan for gold near at the village of Las Cristinas, southern Bolivar State, Venezuela on January 30, 2009. Four centuries after the lure of Venezuelan gold brought ruin to English explorer Sir Walter Raleigh, the riches at one giant mine some say is cursed still haunt treasure hunters from across the globe. But the Las Cristinas saga, involving a ghost town, environmental devastation and fist-sized nuggets, underlines the risks of business in Venezuela, where the draw of natural wealth has been dulled by rule changes and economic turmoil.

This photo from 1997, released by Woods Hole Oceanographic Institution shows the robotic arm of a three-person submersible aquatic vehicle reaching toward a hydrothermal vent in the east Pacific Ocean far off the coast of Chile. New technology and worldwide demand for metals have combined to make deep ocean mining of the mineral-laden liquid spewed from these vents a possibility.

Analyzing a variety of samples from the atmosphere above the Amazon, Ilan Koren and colleagues at the Weizmann Institute in Israel, show in the journal Science that smoke and other so-called "aerosol" particles can encourage or discourage cloud formation, depending on the conditions, and a their new scientific model shows how these two processes produce a joint effect on climate.

Lebanese workers use water pressure to clean-up the oil spill which polluted Rabbit Island, offshore the Nothern Lebanese city of Tripoli, on March 31, 2009.

Dead carp are seen in the "Las Tres Pascualas" lagoon in Concepcion city, some 322 miles (519 km) south of Santiago, Chile on March 30, 2009. Environmentalists say a clandestine dumping of sewage in the lagoon led to the waters being polluted and caused the high rate of fish mortality, local authorities said. Picture taken March 30, 2009.

Russian Emergency Ministry staff watch a blast ripping through the ice covering the Kan river in the town of Kansk some 220 km (136.7 miles) from the Siberian city of Krasnoyarsk April 4, 2009.
