Medha Patkar...Health Condition Worsens
This is only exhibiting the callous attitude of the concerned officials and the government. It is surprising that even the local media is not covering the struggle appropriately with hardly any news appearing in local news papers!
Update: Medha Patkar had broken her fast on the 20th day after the Supreme court of India warned the Government of Gujarat that if necessary the courd would order stopping all work on Sardar Sarovar Project. The court had directed the state government to take all necessary steps to rehabilitate the replaced people of the region.

Medha Patkar - A lone fighter for environment and people.

Medha Patkar, an environmentalist is on fasting for eigth day in a row. She is fasting on to death in protest against the Sardar Sarovar dam project across Narmada river. There was a widespread agitation against Sardar Saroval dam in India led by Medha Patkar and several eminent environmentalists. Recently, it was decided to increase the height of the dam that would reportedly displace several families, and environmentally disastrous. According to the news reports, Medha is fasting for proper rehabilitation of people displaced due the dam construction, and to stop the dam work that would result in environmental disaster. Her condition is reportedly critical, and admitted to AIIMS hospital. It is surprising to know that the government had not done much to rehabilitate the displaced people (because of the dam construction), and address the concerns of the environmentalists.

Arundhaty Roy -Novelist in response to the government trying to suppress the movement by arresting Medha Patkar (Environmentalist):
"The government is building its new India on the backs of the poor. It just does not want to admit it, but it is."

Update: Medha Patkar...Health Condition Worsens
According to reports, Medha had shown very low blood pressure resulting from extreme exhaustion. Her condition is stated to be serious, though the government officials are maintaining that her condition is stable. She is on her 14th day of fasting.
This is only exhibiting the callous attitude of the concerned officials and the government. It is surprising that even the local media is not covering the struggle appropriately with hardly any news appearing in local new papers!
