Organic farming is more eco-friendly as it does not involve the use of chemical fertilizers, weedicides, herbicides, etc. So, option 1 is correct. Reducing the use of private vehicles will reduce pollution. For e.g. No car day in Delhi and Paris were organized recently. So, option 2 is correct. Safeguarding the habitats of indigenous communities, flora and fauna mean taking into account human as well as animal and plant biodiversity, which forms part of sustainable development. So, option 3 is correct. Option 4 goes against the idea of inter-generational equity. We should not compromise on the needs of future generations against the present generation. So, it is the only incorrect option.
