I’ve read in the news that a majority of earth’s population might run out of drinking water. As with many of these kind of predictions it’s difficult to judge the urgency and correctness of it without spending a huge amount of time on it.
From the Bonn Declaration from the "Water in the Anthropocene" conference:
A conference of 500 leading water scientists from around the world today issued a stark warning that, without major reforms, "in the short span of one or two generations, the majority of the 9 billion people on Earth will be living under the handicap of severe pressure on fresh water, an absolutely essential natural resource for which there is no substitute. This handicap will be self-inflicted and is, we believe, entirely avoidable."
I’m wondering if the situation is urgent enough so that it is necessary for everyone to be frugal with water or whether this can only be solved by regulatory means.
