CLAYTON:
Let me get back to water here for a moment, because it's going to be the carrier. We hear about all these diseases, so our natural reaction, besides food safety, is to develop vaccines. And so, we, as humans, all go to the doctor, and get the vaccine for the disease.

But the way our bodies work is this: usually, to get your body to develop antibodies for a killed virus, you have to overload your system with the killed virus. So your T-cells finally see so many of those viruses that they go, "Oh, this is something that I have to build an immunity for." So killed-virus vaccines are usually very expensive; it's usually multiple vaccinations.

You know, those of us who are older and had to be vaccinated for polio, remember we kept having to have the boosters? That was because it was a killed-virus vaccine.

Well, they've since discovered that you can vaccinate what they call a modified live virus. They kind of cripple the virus, and if they give you an injection of that, it's one time only. Because it's kind of alive, the T-cells recognize it more quickly, and it revs up your immune system more completely and thoroughly, so you only need one shot. But the problem is, technically you now have a live virus in your body...

You get a little bit ill one evening, and vomit into the toilet. Plus, you're crying... so you wash your face. The virus you have goes right down the drain. You know, our water treatment systems have no regulation or design to treat the viruses in the water we flush through the system.

JEFF:
Yeah, just the bacteria.

CLAYTON: Yeah, just the bacteria. But nothing about viruses -- nothing about prions. Okay, so if we start vaccinating ourselves to protect ourselves from all these diseases, think what we're shedding into the water system that isn't being protected.

And the other thing I will submit to you is - what do your parents do with leftover coffee in the morning - every evening?

MERIAH:
We don't drink coffee.

CLAYTON:
Oh, good job. People pour it down the sink. Our treatment facilities don't treat for caffeine.

IVY:
Oh ho ho! All that caffeine that's going down the drain…

CLAYTON:
Not only that, but the individual that has some emotional problems, so they're prescribed with Prozac. You shed Prozac through your urine, okay? Women take the Pill, okay? Older women take estrogen therapy? And we all shed viruses from vaccines. Prozac and caffeine may be combining out there in our water resources to create some horrific compounds that are really damaging our wildlife resources, and the sustainability of the ecosystem - by-products from our style of life that we don't even think about.

Until I brought this up, if I asked you what a pollutant in water was, what would you have told me?

JEFF:
An aluminum can floating down the river.

CLAYTON:
Yeah, pesticides, oil spills, right?

ARIA:
But we don't think viruses. Or caffeine.

CLAYTON:
Also - we've been told that as soon as many of these bacteria leave the body, and don't have this nice constant temperature, they die. But we know, for example, that Scottish researchers, Canadian researchers, and Iraqi researchers have found Streptococcus, which tends to be pretty bad, surviving up to ninety days. Some of the fecal E. coli, surviving for forty to fifty days in water, just slightly above freezing.

So I would suggest to you, as you look at your footprints, that there are secondary impacts that we have that may, in time, become as serious, or more serious than some of the things that we are now concerned about.

You guys are all depressed now.

IVY:
Yeah, this is really uplifting.

JEFF:
I'm not having water at dinner, that's all I know.

CLAYTON:
Or eating meat.

JEFF:
Yeah, or eating meat!
