World's options for water resources
- The world has three options to deal with its crises in water supplies
- Water can be transferred from areas of surplus to places scarcity, like large cities
- There can be massive increase in the building of desalination plants which turn seawater into fresh water, although this will benefit only coastal locations
- The third option is to recycle as much as possible with the aid of innovations in engineering, biotechnology and, above all, chemistry. This alternative is considered the most sustainable because it consumes less energy, less expensive and would require the allocation of fewer resources
