Water security
-
In the UK, the majority of people tend to be water secure.
In California,despite the heat and lack of rainfall, individuals tend to be water secure.
In the Middle east, people may not be water secure due to the lack of safety. The middle east is currently largely a warzone.
In Nigeria, there is a lack of water security as water in this area tends to be polluted, and thus not clean.
However, it is key to note that a water secure person can very quickly become insecure.
Business as usual
If every human continues to live as we do today, there will simply not be enough water.
There will by a 56% increase in the demand for water by 2025 (Predicted/ calculated based on water level data being used in the year 2000).
Even if everyone implemented sustainable measures, we will still need 20% more water due to the increase in demand.
