Can you answer this IMPOSSIBLE Question? How have human activities impacted the sustainability of water resources on planet?how have humans used technology to change the sustainability of water on earth!?

Answer:

To answer this let me define what sustainability is..

The rate of change of resources=0 i.e,if we consider a resource it should not only serve the needs right now, but also it should be able to meet the future demand.There are many human activities like bore wells,discharge of effluents into water bodies( sources of drinking water),urbanization etc.These activities effects water resources by lowering the groundwater levels,depleting the surface water quality etc.
