Though portrayed as developmental projects, the serious negative impacts of mega hydro projects on the fragile environment of Sikkim have seriously affected poor citizens of the state and are further likely to affect the rich bio-diversity of the state. These projects will also erode the cultural sensitivities and homes of the indigenous populations in the state. All the voices of popular discontent, concerns and apprehension have been totally ignored and the saga of sufferings of the people and the destruction of the environment carries on. The Lepcha are protesting the dams on many grounds: that as nature-worshippers their land is sacred and should not be destroyed by development; that the Dzongu is recognized as a reserve, and as only Lepchas who are from there are allowed to enter it should not be the site for the hydro projects; that the projects will bring thousands of worker from outside Sikkim into Dzongu for several years while work is completed and they will outnumbers the population of Lepchas; the gradual transfer of population due to various projects issues of national interest have almost outnumbered the local inhabitants. The increase in the population has caused serious damage to the environment, demography, culture and religion thus hurting the sentiments of the impoverished populace and also endangering their survival in their natural habitat.
