The sailing stones, also known as sliding rocks and moving rocks, are a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal intervention. They have been recorded and studied in a number of places around Racetrack Playa, Death Valley, where the number and length of travel grooves are notable. The force behind their movement is not understood and is the subject of research.

Mammatus Clouds
Also known as mammatocumulus, meaning “bumpy clouds”, they are a cellular pattern of pouches hanging underneath the base of a cloud. Composed primarily of ice, Mammatus Clouds can extend for hundreds of miles in each direction, while individual formations can remain visibly static for ten to fifteen minutes at a time.

A fisherman on the Li River near Xingping, Guilin Province, China, uses cormorants to help him. The fish are attracted to the light from the lamp, and the cormorants, which have rings around their necks to prevent them from swallowing the larger fish, catch the fish and bring them to the raft. Once the fisherman has enough to feed his family the rings are removed and the birds are fed.

"Tree of life", Tsavo national park, Kenya. This acacia is a symbol of life in the vast expanses of thorny savanna, where wild animals come to take advantage of its leaves or its shade. Tsavo National Park in southeastern Kenya, crossed by the Nairobi-Mombasa road and railway axis, is the country's largest protected area (8,200 square miles, or 21,000 square kilometers) and was declared a national park in 1948.

Iraqi tank graveyard in the desert near Al Jahrah, Kuwait. This graveyard of tanks will bear witness for many years to the damage that war causes both to the environment and to human health. In 1991, during the first Gulf War, a million depleted uranium shells were fired at Iraqi forces, spreading toxic, radioactive dust for miles around. Such dust is known to have lasting effects on the environment and to cause various forms of cancer and other serious illnesses among humans.
