I don't have subscriptions that allow me to see the text of any
hits I came up with though it does seem that science has addressed real world
limits of

hits since 2007) recent science that more than skims the issues.
Gleick points out three areas where water
hits peak
limits —
renewable water, nonrenewable water, and ecological water — and notes that we seem to have already passed a tipping point on all three.
