Uncovering life in the Antarctic Dry Valleys | Craig Cary | TEDxScottBase

[@Christina-mx1nr]

Really interesting and informative presentation. So important and under recognized as such by the general public

[@Follicularis39]

Amazing effort to preserve and protect one of our last pristine ecosystems. Visited Antarctica in Feb 2019 down to Terra Firma Island (68S 39,5°) which certainly changed my view view of the (only) planet we live on..

[@Christina-mx1nr]

Nothing happens in a vacuum He’s ultimately working to protect all of it, us included, directly or indirectly

[@thaovyle91]

Thanks for the talk! I completely agree with the importance of bacteria and microorganism but unfortunately so far it doesn't receive much attentions that it deserved. It's great that we have people like you who devote their life for the not so sexy job but really important to everyone of us.

[@laomark9583]

Craig, I completely agree w/ you w/ respect to the fundamental importance of bacteria (microorganisms in general, "the-non-seenmes"). I've been a marine aquaculture scientist for almost 40 years and have worked all over the world. I always regarded well the microorganisms but after working for a long while in Taiwan in the late 80's with local commercial aquafarmers, my view and understanding of these organisms widely amplified. I then realized that these can be some of our best friends (and worst too, of course). The most successful aquaculturists in Taiwan (and now in China and most Asia) put a great effort in manipulating/ controling the bacteria/ microorganisms in their farming water. Meanwhile "westernized" aquaculture methods tend to eliminate bacteria. Their long observational knowledge led them to affirm that to cultivate/grow the fish/shrimp one has to "cultivate the water"... they would culture the water and the "good grown" fish would be the result. Astonished w/ my undeniable witness of their success, I published 2 articles in the World Aquaculture Society Magazine (one of them was presented in an Internation Conference in France) to try to open up the view of this industry elsewhere: 1) Zen and the Art of Aquafarming: a close look at Taiwanese aquaculture practices; 2) The Tao of Aquaculture: cultivating aquatic organisms in concert with their microscopic world. I would be keen to learn more about your work, Craig and congratulate you not only for your work but also for your vision.

Outstanding Stage design I must say.

The first half you understand and then your understanding crumbles by the end

[@izzzzzz6]

Whats the permafrost situation in the dry valleys? Hope you got some good hot spring action in.

When most people don't care about something it's just because they know nothing about it, and prefer to stay this way rather than embracing their ignorance and learn something

[@limpingoatfarm]

I reported solar scams and herbal and dental etc to the FTC I recommend you do likewise, they are aimed at the intellectually incapable of recognizing the scam. Help others when you think you see a danger of them being scammed by ADS report them.

[@Christina-mx1nr]

Now what will the fungi and molds do with all of that melt water? 😱

[@grahampalmer]

This guy is so enthusiastic about his bacteria. Unfortunately this talk needed more and simple examples upfront of their value to us and why they need to be protected. It seemed to me that these bacteria do a fine job of coping with changes to their environment (some man-made) by changing themselves, and very fast, so don't need our help. Basically they don't need us and why should they? If a 'strain' (not sure about the terminology) of bacteria changes, or even dies-out, I still don't understand the problem hinted at by suggested 'need' to protect this environment. Can someone tell me where my thinking is lacking?

[@annabarhorst8344]

These environments have only a very few organisms occupying them, and thus have an ecosystem that is nice and simple to begin studying. Even with current sequencing technology, it is incredibly difficult to get a picture of what organisms are in an environment, what they're doing, and their populations. Also, scientists are studying prokaryotes in Antarctica as a model of what life may look like on other planets. Life would have to be chemolithotrophic, and adapted to extreme cold and salt. Brine channels in the ice is a fairly good model.

eDNA freeze up down there?

im watching that

The talk was all over the place. I didn't get anything tangible out of it.

[@skellz215]

Yeah he was everywhere right 😒

[@qristv1912]

ive been putting these tiniest organisms in my stomach taking a probiotic lol

[@emirkuvvet]

I'm asking everyone watching this video after me: *What brought you here?* I came here after watching a video about the dry valleys

[@myshelleseamore6319]

Antarctic... Lol. I just have a wierd feeling that it's tropical down south. New Zealand is beautiful. ;-). This video was one of the only results that appeared to have any substance when I searched Antarctic vegetation. I wish I had a better search term. Any ideas?

[@AnkitGarg-bp6vk]

Don't like they are fake
