How many people, and how much agricultural, business, tourist, industrial activity, etc.  can the water supply for the coastal area support?

6.7.13               Has global water availability ‘peaked’?  As a finite resource, it may be water extraction rates of ancient waters which cannot be replenished and shallower waters that are rain replenished are now reducing at a dangerous rate.  This Guardian article is highly informative and will stiffen your resolve to get a water meter and cut, cut, cut water use.  The world should be reducing food animal farming which takes staggering amounts of water, both directly and as irrigation for feed crops.  But it won’t.
20.5.13            Southern Water announce they are planning for a future that sees recycled sewage water used for household supplies.  The plan is to extract the water, clean it up and discharge it into rivers – presumably because a quasi-natural cleanup is further needed – before re-extracting it from these rivers and cleaning it again.   It willthen be sent to our homes to use for drinking, and etc.  Nice.  A clear indication of population overload as compared with the natural resources to support the level being encouraged.
We are encouraged not to buy bottled water.  But mineral water that is extracted from very deep sources has undergone trickle-through earth, various levels and rocks and is mineralised by that process.  Lack of oxygen along the way presumably also means bacteria and viruses do not survive.  But over time, surely the habits of the last 50-100 years will find us out as the pharmaceutical and agri-business chemicals we excrete increasingly turn up in the water supply.
Scientists working around the Great Lakes in North America were finding in the late 1980’s that fish were changing sex in these waters due to the presence of oestrogen contamination of the waters.  Only in the last ten years has this more widespread phenomenon been reported in the media, however.
