New Delhi: Extending support to 80-year-old noted environmentalist GD Agarwal commonly known as Swami Gyan Swaroop, who is on fast unto death since January 15 in demand of saving the Ganga river, anti-graft crusader Anna Hazare on Thursday wrote to Prime Minister Manmohan Singh appealing him to intervene into the matter.

The Gandhian activist has sought the PM’s intervention in saving the life of Agarwal who has been admitted to AIIMS following deterioration in his health condition.

In the letter, Hazare has urged the Prime Minister to immediately call a meeting of the National Ganga River Basin Authority (NGRBA) in the view of deteriorating condition of the octogenarian environmentalist.

Making special reference to the appalling condition of river Ganga, Hazare said, “Despite the continuous decline in condition of the holy river, only two meetings have been held so far by the NGRBA since its establishment three years ago.”

Accusing the lackadaisical approach being adopted by the government in tackling the Ganga issue, he said that it is unfortunate that no such meeting have been held in the past one-and-a-half years.

The 70-year old Gandhian activist further said that being the chairman of NGRBA, the Prime Minister holds immense responsibility in solving the age-old Ganga issue.

The Prime Minister had set up the NGRBA in 2009, which is a Central Government constituted body for cleaning the Ganga river.

Hazare also mentioned in his letter that four members of the NGRBA have resigned. While Rajendra Singh resigned as the chairman NGRBA last week over government's insensitivity towards Agarwal and gross negligence towards worsening state of the holy river, two other members have also resigned over the issue.
