00:00A mere 0.007% of Earth's vast water reserves is actually fit for human consumption, and
00:12this precious fraction is dwindling each year due to relentless pollution.
00:18In the United States, rivers are tainted with an average of 1 milliliter of cholesterol
00:22per million liters of water, a concentration that can be whimsically compared to a strip
00:27of toilet paper stretching around the globe two and a half times.
00:33Annually U.S. Industries churn out approximately 3.63 million
00:38tons of hazardous organic pollutants, yet only a scant 10% are disposed of in ways that
00:44meet environmental standards.
00:47The most significant contributors to this deluge of pollutants are industries reliant
00:51on organic materials, with the food industry being particularly culpable.
00:57Consider perchloroethylene, a solvent prevalent in dry cleaning.
01:03Its toxicity is such that regulations restrict its presence in water to a mere five parts
01:07per billion, akin to five drops of gasoline in a rail tank car holding 113,500 liters.
01:15Moreover, traces of common pharmaceuticals often seep into the water supply, though usually
01:21at minimal concentrations.
01:24For instance, at a contamination level of one part per billion, a person would need
01:29to consume 3.8 liters of such water daily for several years to ingest the equivalent
01:34of a single pill.
01:36Specifically, it would take 3.5 years for a Valium pill, 14.5 years for a Benadryl capsule,
01:43and a staggering 58 years for a children's Tylenol pill.
01:48Thankfully, homeopathy remains a debunked practice.
01:52Earth is home to about 525 million cubic kilometers of water, a quantity that has remained stable
01:59over the past 2 billion years.
02:03Over a century, a water molecule typically spends 98 years in the ocean, 20 months as
02:08ice, 2 weeks in lakes and rivers, and less than a week in the atmosphere.
02:14Remarkably, water has the unparalleled ability to dissolve more substances than any other
02:19liquid.
