This is my overview of the final session of TedX Cape Town 2011.

If you are interested in reading the rest of the entries, you can find them here:

Caron von Zeil – Reclaiming Camissa
In this amazing presentation, Caron spoke about Cape Town, and the river system running under it. She spoke about how we could use the river system, which is currently being used for sewage, to completely transform Cape Town into a beautiful green city, in harmony with nature.

I know for a fact that I am not doing justice to Caron’s vision, since I find it hard to bring across the conviction and beauty of what she has imagined and is working on.

Alison LewisBe bold and mighty forces will come to your aid

In this presentation, Alison spoke about the experiments that she and her team have been working on, using freezing to purify water, while in the process separating the crystals of the products, so that they are available for sale.

The work they are doing is very impressive, and Alison also spoke about the difficulties that her team has encountered in their experiments.

Eran EyalTechnological Social Anthropology

This was a pre-recorded presentation, due to Eran being out of the country at the time. In it, he spoke about the idea that the actions and ideas that we spread right now will have a massive impact in the coming years, as we approach a type of singularity.

Anthony TurtonReinventing Uncivilisation

A lot of people said that this was their favourite presentation, I am not sure if I agree with their estimation, while definitely thought provoking, it lacked some of the impact that the other presentations had on me.

Anthony spoke about the relationship of man and nature, and claims that the correct relationship is one of humbleness with regards to nature, rather than seeking to become master of it. My own views are somewhat complex, and I might write a post on it some other time.

Afterwards, he spoke about the uranium deposits that have been extracted from the mines in the Witwatersrand area, and allowed to seep into the river systems in the area. He then pointed out that there is currently no research available in the effects that continuous exposure to a low level of radiation and heavy metals has on people.

This portion of the talk had a very scare tactic feel to it, and the comparison with Chernobyl reinforced the feel for me, which might be what put me off his talk.

I do agree with a point that he also felt very strongly about: It is our duty to know where out money is going, and to ensure that our provident funds and other investments are handled in an ethical ways, and invested in companies that help the planet.

Clinton SmithRedesigning the Perception of Beauty

Here, Clinton showed how his team worked on special effects, and the amount of effort and the attention to detail that they put into their work is truly staggering, especially for something that will be on screen for only a couple of minutes at the most.

Mike MarkovinaMoving Sushi

Edit: I originally got the timeline and number of coutries wrong, as Michel helpfully pointed out

The final presentation of TedX was about Mike’s and his wife’s journey to document the people all around the world who are doing amazing things with ocean life conservation and fisheries management. they did this by driving to Japan and back, taking 24 months to do it, and visiting 42 countries in the process.

Mike tells an engaging story, and the tales of the people they have met are truly inspired.
