Jim Van Horne, CBC, Professor discussed on Quirks and Quarks


In West and with that it's time for another quirks and quarks question. My name is Jim Van Horne. And I'm from Koslow Bruce Columbia and I've been a a journeyman plumber for fifty plus years and have dealt with human waste products from time to time the financial cost of getting rid of this waste with water and sewage treatment in a staggering. which brings me to? My question is the digestive system in humans and animals that inefficient or is it. Our Diet produces reduces so much of the waste stream. And here's the answer. I'm Marlon Bucko. I'm from university. Wealth and I'm a professor of microbiology here and Kinda Teresa's says chat and I study in My lab who human poop in particular and I think this is a great question because we don't like to think about poop too much because it's kind of disgusting discussing but what you should know about but it's actually not just undigested food about seventy five percent of the weight of an average poop is from voltaren altering facts and the remaining twenty five percents overhaul about is actually bacteria itself and other microbes makeup positive. What we got microbiome these microbes? It's not live as part of your microbial ecosystem and you'll guts and they carry out of work for you some very important only a very small amount of tool it's actually undigested food and the average healthy person and so. I don't really think that it's necessarily a problem of too much undigested food. I think that the problem with the amount of sewage is being produced. It's just because there's a lot of people and also a lot of animals so the microbes are very very important for us that very important to help us break down food and I'll buddies but once once they viva buddies they work doesn't stop and in fact many of those microbes become an important also wastewater treatment process and we harness their power if you like purification dwarf occasion at at removing some of the impurities from the water now. I think it's very important to understand that these microbes really need to be the healthy and we tend to flush a lot of things down the toilet that we perhaps shouldn't and these kind of interfere with the wastewater treatment process. And so I guess in the answer to the question question. It's really not so much about what we can do to reduce the amount of on digested waste product. That we can produce is what we can do to make sure that we produce the best policy poop that we can and they can break down food and by the way Dr Allen Vercoe is a professor of microbiology and Canada.
