Chipko movement brought out which of the following issue?

The correct answer is Option 2- Ecological depletion

Social movements raised various issues about the model of economic development that India had opted at the time of Independence. The Chipko movement brought out the issue of ecological depletion whereas the farmers complained of neglect of the agricultural sector.  Social and material conditions of Dalits led to their mass struggles whereas the anti-arrack movement focused on the negative fallouts of what was considered development. The issue implicit in all these movements was made explicit by the movements against displacement caused by huge developmental projects.
