Infrastructure is a good for human development but it isn't good for our environment. The development projects in himalaya region is to set new new challenges like landslide earthquick etc. Recently in Uttrakhand rail tunnel project engineer sees many labour are under the tunnel the many rock blocked the route. Now we have understand that we can't fight against the nature. Now it is very necessary to know about the importance of nature. Many rail project is active in our country like railway project in north eastern India like arunchal pradesh tawang rail project. In North India delhi manali rail project is very important in prospect to India China border row so it is very important project to connect Himachal to ladakh leh. In our himalaya region is very sensitive due to weather conditions, it soil & rock bondage is very week so, we have to follow sustainable development which means development with any without damage of environment. It is only way to restore ecology.
