"The cholera epidemic in Haiti is spreading twice as fast as had been estimated and is likely to result in hundreds of thousands of cases in the coming months, the UN says."

Hurricane Tomas seems to be worsening conditions favorable to the spread of cholera in Haiti, where some streets have been turned into rivers.

"For nearly 10 months, more than 1 million people in Haiti's earthquake camps have been walking a precarious line: Trying to get out and find good homes without losing their tents and the possessions they still have. Now a potential hurricane threatens to upend that careful balance. The Haitian government has called for the voluntary evacuation of all the quake zone's camps ahead of Friday's expected arrival of Tropical Storm Tomas, telling residents to find somewhere else to go."

"PORT-AU-PRINCE, Haiti -- This battered country is bracing for the arrival of a storm later this week that could complicate its efforts to control a cholera outbreak, and expose hundreds of thousands of earthquake survivors living in tent cities to high winds and heavy rains."

"They ran for blocks when they saw the big truck with the Minnesota license plate roll by. Little girls and old women, little boys and young men, all chasing the shiny silver tanker down streets of Cite Soleil, one of the world’s worst slums. Past fly-infested garbage piles, by canals reeking of raw sewage, they carried buckets, pans, pots, tubs — anything that could hold what has become gold in the ruins of Haiti’s catastrophic earthquake: clean water."

Cholera may be the next disaster in Haiti as thousands in tent cities face the coming rainy season without sanitation.

"Long-term efforts to help Haiti recover from the earthquake will have to reverse environmental damage such as near-total deforestation that threatens food and water supplies for the Caribbean nation, experts say."

Pablo Fajardo is the David to the oil Goliath Chevron Texaco. He represents about 30,000 Ecuadorians in a class action suit trying to clean up the oily mess in their part of the Amazon. The case, filed in 1993, goes back as far as 1964, when the U.S. company Texaco began oil exploration there. The suit alleges that Texaco dumped 18.5 billion gallons of 'produced water' -- which can contain dissolved inorganic salts, dispersed oil droplets and dissolved oil; treatment and workover chemicals; dissolved gases, particularly hydrogen sulfide and carbon dioxide; and bacteria and other living organisms.
