Driving in Johannesburg one day, Tapiwa Chiwewe noticed an enormous cloud of air pollution hanging over the city. He was curious and concerned but not an environmental expert — so he did some research and discovered that nearly 14 percent of all deaths worldwide in 2012 were caused by household and ambient air pollution. With this knowledge and an urge to do something about it, Chiwewe and his colleagues developed a platform that uncovers trends in pollution and helps city planners make better decisions. "Sometimes just one fresh perspective, one new skill set, can make the conditions right for something remarkable to happen," Chiwewe says. "But you need to be bold enough to try."

no subtitle…?
Air pollution is a result of industrialization. Industrialization is a result of Western Colonization. To solve air pollution problem, South Africans need to get rid of the root cause, and return Africa to its primitive state — hunting and gathering naked without the whites. Then introduce the power of Wakanda and its vibranium, and build Africa’s own civilization from the ground up!
Kerwin C i think most of them that
Lol.
slow roll troll. good job.
Thing is, did industry lead to western colonization or did western colonization lead to industry?
Depending on the answer, we will get industry and air pollution either way.
Wakanda doesn’t pollute!
This right here is one of the TED’s most inspiring talks
I was starting to think most TED viewers were just going to dislike every black speaker they have
mp517q give it time. Winter is coming.
Speakers are disliked when their speeches are bad. If it’s someone with a brain, such as Neil Degrasse Tyson, then he would be very popular. If instead TED invites clueless nobodies just because they have dark skin, you will end up with a lot of awful speeches. Are you perhaps one of those people who think that every time a black speaker is disliked it must be because of racism?
Miranox Are you new to the recent Ted talk comments section? There have been some very good talks from African speakers that have gotten a ton of ignorant comments. Now while i can attribute a bit of that to trolling, alot of the comments or dislikes stem from the fact that the talker doesn’t look like them and isnt talking about a situation which they have been in or need help getting out of. Its not rascism, its a lack of an inability to think of anybody other then themselves.
Jordan Peterson TRIGGERED
AlHoresmi ?
Avery Lemons he’s really big on telling people to stop fixing big problems if they can’t fix their private small ones.
AlHoresmi
Funny, when I read the title, I thought “Jordan Peterson haters triggered!”
можно сердце ? ))) https://youtu.be/Pd-CAqWScbg , лайк пост ,что бы в топ(спасибо бро)
Ah! Another novel idea. Except the people who control the doors that open to opportunity have decided if you aren’t an “expert” you aren’t worth listening to. Real life is not parallel to our dreams.
Do you know how many stories i hear from Employees who work in IT and don’t even know what CTRL+C means?
Conex Xenon *facepalm*
Yeah… and the problem is people can’t seem to differentiate between those people and people with creativity, intelligence, and intellect even if they’re at the same rung.
WormyLeWorm Story of my life. If you have a degree it has to be prestigious or it doesn’t count. If you don’t have one then who cares what you think. Catch -22.
That’s why we start our own businesses.
1) Great Talk! 2) That is some amazing software that i hope will get the recognition that it deserves and is implemented around the world. 3) I am highly upset that perfectly placed “Taken” reference got so passed over.
BlackRufio !!! A negroe is not gonna tell how to handle my pollution
NKLOP Nanii??
He was already an expert in one field. So in a way you do have to be an expert.
Back in the 1950s we had a serious pollution problem in Western nations. Factories producing phosphate fertilisers output an extremely toxic chemical into the atmosphere that would rain down on farm land, destroying the health of livestock and killing crops. They were forced to deal with their toxic waste output so installed some “atmospheric scrubbers” (aka Wet Scrubbers). This reduced the toxic chemical in the chimney fumes and saved the surrounding area from the pollution.
The toxic waste kept building up in plastic containers, occasionally breaking and spilling over the concrete floors where it would eat through and leach into the soil. Something needed to be done about it. Government and industry got together and decided to trickle it off into the drinking water supply and claim that, because the chemical contains “fluorine” as part of its makeup, that it may perhaps be beneficial for people’s teeth. Government wrote the legislation (1985 c.63) and thus Water Fluoridation was born. The toxic waste problem was “solved” by non chemists.
Ever since, scientists have been finding out just how toxic the chemical (hexafluorosilicic acid) is for human health and have been trying to get something done about it. However, nobody has come up with a real solution to the problem of what to do if we stop dumping it into the drinking water supply, so it continues to this day.
My story doesn’t really have a point. It’s just another problem that humans haven’t managed to solve. Perhaps a chemist reading this comment may be able to find a way of reacting hexafluorosilicic acid into something else that’s actually safe and/or useful.
Jim Griffiths you bore me
+NKLOP
Can’t please everyone.
Our willpower and imagination are a guiding light enabling us to chart new paths and navigate through obstacles
What I’ve learnt is that when embarking on a challenging endeavour, that advances a course that we firmly believe in it is important to focus on the possibility of success and consider the consequence of not taking action. We should not get distracted by resistance and opposition but this should motivate us further.
Heena Artist I have learned that you need to eat excrement
NKLOP i don’t think you will taste that good
Why be an expert when you can just beg from westerners?
Thank you for subtitles!!!
Perfection stifles creativity
Bullshit
