A fracking truck next to a site being fracked near Wasco in California's Central Valley, USA. Fracking for natural gas and oil, has reduced energy prices in the US, but fracking is a water hungry industry, that competes directly with the agricultural sector for water. After a 4 year long drought water is running out. Fracking also contaminates ground water supplies from all the chemicals that are pumped underground to frack the fossil fuel bearing rocks.

Mexican aztec dress gods at Grand Palladium White Sand Resort and Spa in Riviera Maya, Yucatan Peninsula, Quintana Roo, Caribbean Coast, Mexico. Aztec clothing was generally loose fitting and did not completely cover the body. When the Spanish arrived in Mexico, the people were surprised to see them in their full armour, with only their faces exposed. Aztec clothes were generally made of cotton (which was imported) or ayate fiber, made from the Maguey Cactus (also called the Century Plant or American Aloe). Women would weave the fibers into clothing, a task girls were taught as young teenagers. Because of their vast trading network, the Aztecs were able to make use of a beautiful array of dyes, creating the brilliant

Aerial view of Punta Allen Sian Ka'an Reserve, Yucatan Peninsula, Mexico. Red lagoon near Boca Paila Bridge. In the language of the Mayan peoples who once inhabited this region, Sian Ka'an means Origin of the Sky. Located on the east coast of the Yucatán peninsula, this biosphere reserve contains tropical forests, mangroves and marshes, as well as a large marine section intersected by a barrier reef. It provides a habitat for a remarkably rich flora and a fauna comprising more than 300 species of birds, as well as a large number of the region's characteristic terrestrial vertebrates, which cohabit in the diverse environment formed by its complex hydrological system. Along its roughly 120 kilometres of coastline, the property covers over 400,000 hectares of land ranging from sea level to only ten m.a.s.l. The property boasts diverse tropical forests, palm savannah, one of the most pristine wetlands in the region, lagoons, extensive mangrove stands, as well as sandy beaches and dunes. The 120,000 hectares of marine area protect a valuable part of the Mesoamerican Barrier Reef and seagrass beds in the shallow bays. The lush green of the forests and the many shades of blue of the lagoons and the Caribbean Sea under a wide sky offer fascinating visual impressions.

Aerial views of El Castillo and the Ruins of the Mayan temple grounds at Tulum, Quintana Roo, Yucatan, Mexico. Tulum is the site of a pre-Columbian Mayan walled city which served as a major port for Coba, in the Mexican state of Quintana Roo. The ruins are situated on 12 meter 39 ft tall cliffs along the east coast of the Yucatán Peninsula on the Caribbean Sea in the state of Quintana Roo, Mexico. Tulum was one of the last cities built and inhabited by the Maya; it was at its height between the 13th and 15th centuries and managed to survive about 70 years after the Spanish began occupying Mexico. Old World diseases brought by the Spanish settlers appear to have resulted in very high fatalities, disrupting the society, and eventually causing the city to be abandoned.

Gran Cenote de Tulum in Yucatan Peninsula, Quintana Roo, Mexico. There are thousands of cenotes dotted all over Mexico���s Yucatan Peninsula, and their existence is as much a defining characteristic of the region as is the distinct geological feature from which they result. Once revered by the ancient Mayans as sacred wells, they are now magnets for tourists, adventurers, and explorers alike.
