Voicing concern over environment degradation, the National Green Tribunal (NGT) today observed that people will soon need to carry oxygen cylinders as it pulled up authorities in Himachal Pradesh for not planting a single tree after clearing a forest area for a road project. "Half of the country is facing floods and half of the country is dry. Temperature of Shimla is going up. Show us one tree which you have planted. Willthe road give you oxygen? It is tree which would give us oxygen.” "People are falling sick. Time is not far away when people will have to carry oxygen cylinders," a bench headed by NGT Chairperson Swatanter Kumar said. Noting the "nobody bothers" attitude for this key issue, the green body pointed out authorities concerned haven’t shown even a single photograph where trees have been planted. When the counsel appearing for the state told the bench that the project was of a national importance, the bench said, "We have seen what is in the national interest. Plant one lakh trees and then come to us." The bench said that it would hear the matter on August 11. The tribunal had earlier taken suo motu cognisance of the matter pertaining to cutting of trees from Parwanoo to Shoghi in Himachal Pradesh. The NGT had directed the conservator of forest to file an affidavit giving details of number of trees cut in the stretch and had also asked National Highways Authority of India (NHAI) and state government to file their reports on the issue.
