Explanation:
The world is undergoing an overarching danger of disastrous peril which would be strong enough to wipe out the last traces of human civilisation to its bequeathed end. To prevent such happenings, it becomes urgent that we employ sustainable techniques in construction and developmental activities.
These sustainable techniques are advantageous to humans at large due to the following benefits-

2. Environment friendly- This is another important aspect of it. Sustainable techniques are distinct from others due to its environment-friendly nature.
3. Cost-effective in long run-These techniques prove to be cost-effective in longer periods. Due to extended shelf time, the cost per unit time tends to be low.
4. No harmful effect on humans-Sustainable techniques casts minimal to no impact on human, unlike erratic techniques.
5. Judicious use of available resource-Sustainable techniques re judicious in the utilisation of the existing resources. They make the optimum utilisation of the resources thus enabling humans to enjoy the maximum potential use of the resources.
