Which one of the following is not responsbile for water shortage?

Explanation:

Problem & Solutions to tackling water shortages:

1. Population growth control – It is beneficial to limit the expansion of the population.
2. Climate change – Decreasing the effects of global warming by pursuing cleaner energies, that will in turn help with the water crises as the world find new technologies to keep water safe and use less energy to do so.
3. Transfer of technologies – More developed countries having a higher level of technological advancement can help greatly by sharing their advancement with developing countries.
4. Education and awareness – Educate people better on the causes and effects of the water crisis, as well as what they can do to help the society. So, they, in turn, can teach others and raise awareness.
5. Innovative technologies – Incentivize innovation in the fields of water recycling, conservation and consumption.
6. Improved irrigation – Irrigation techniques should be improved. Roughly 70% of the world’s freshwater is used to grow crops; we could improve these practices to use much less water than currently in use.
7. Increasing Water pricing – Increasing the price of water to reduce pollution, but that would take water even further out of reach by those experiencing poverty.
8. Rainwater harvesting – Areas with very little groundwater reserves can greatly improve the way they harvest rainwater by building larger facilities and incorporating better technologies.
