I am also perplexed as to why you assumed that environmentalists started objecting on this today. The truth is that they have objected ever since the the project was initailly disussed. Now with the UPA getting ready to implement it they have merely beocme more vocal. When it comes to making such major changes in the environment it is important an environmental impact study is done before the project is approved . Not that the government goes ahead and environmentalist have the task of proving the action as being injurious to the environment.
