Water crisis
“ One-third of the world's population is living in water-scarce areas, say scientists behind a 5-year analysis of global water resources. The finding is a worrying update to an older study by the same team, who had previously predicted that such a situation would not arrive until 2025.”
Next wars will be for water not oil. Will we be able to avoid that or will we just go ahead as we always seem to have done? Another self-inflicted situation, fueling my doubts on the intelligence of humans.
