About this problem, in one's childhood everybody may have doubt in the heart, why tellurian water won't expire a few years, and install the water in bottle to you can expire? And tellurian fresh water or the view that seawater did not expire, that expires this is what meaning, be whose regulation expire, it is scientist or the person that produce water, is this why?
See news just know later, water won't expire originally, this expires is a kind of definition that our mankind gives it. The water that then we define expired is what meaning, the definition that we say is water was given to pollute by the bacterium. Ask with respect to somebody at that time, are those bottled and clean water to pass what national food safety detects? And still pass disinfection, the water that compares nature is much cleaner, should not expire to just be opposite. Actually otherwise, the water that we drink, no matter kill poison to eliminate bacterium through what kind of, what there still still are a lot of minimums inside water is microbial or bacterium, what these bacteria breed inside period of time is very slow very few also, so this time paragraph make the expiration period inside, after spending the expiration period, what the bacterium breeds gradually is more, do not suit people drinkable, so water deteriorated, namely what we say expired.
Still having a reason is, the water that did not expire on our earth is vivid water, the water that flows namely. The ancients often says, disaster water not corrupt, it is this truth. Do not believe you to look, a dead pool, did not pass how long, hookworm forgive bug can be born inside, it is leech even. And flowing water is flowing all the time, biology of our junior high school has learned, clay, sand, the natural thing such as plant rootstock is had filter action, and flowing water passes from edaphic midstream everyday, ceaseless be filtered to purify, so it holds the position that updates ceaselessly all the time, say to won't expire forever so.
Water is the source of our life, it is flowing water no matter lentic, we should be protected, want to make flowing water cleaner, want to let lentic work rise, the water of such life just is met in a steady stream is constant, only such, the evolution with our long ability continues, ability gives our descendants a good environment, beautiful future.
