On July 26, 1943, Los Angeles was blanketed by a thick gas that stung people’s eyes and blocked out the Sun. Panicked residents believed their city had been attacked using chemical warfare. But the cloud wasn’t an act of war. It was smog. So what is this thick gray haze actually made of? And why does it affect some cities and not others? Kim Preshoff details the science behind smog.
Lesson by Kim Preshoff, directed by Juan M. Urbina Studios.

Very good video! Thank you Kim Preshoff for sharing this with us :)
I live in Santiago de Chile, a city historically affected by smog. The city lies in a valley, which makes the problem worse. In the last years, luckily, the cases of extreme pollution have dropped significantly thanks to state policies, but there is still a lot to do.
Thank you Kim for taking the time to share your knowledge with us
Fantastic video, so nice and clear! Thanks for putting it together Kim
The way she pronounced Glasgow.
is incredibly irritating
ahahahha glosgaow
Khushil Parikh you pronounce the "o" in Glasgow.
I came looking for this comment
Khushil Parikh, it's Glas-go (at least in British English, not sure about American English)
Thanks Miss Kim
Thank you all the way from Germany, Kim! I wish I had had a great teacher such as yourself back when I was in school. Keep making the world a better place by continuing to educate - you're marvelous at that!

Kim"s lessons are great! I love all of your videos so far. keep up great work guys!!!
Thanks Mrs. Preshoff for this enlightening lesson on smog. Was a joy to watch and learn so much!
Hi, generally a good video. However, nitrous oxide (N2O) is not the same as nitric oxide, also know as nitrogen dioxide (NO2 or N2O4 since it exists as a dimer), which is what the real problem is in smog. This is often represented as NOx. These are very different compounds with completely different properties. They are as different as water and hydrogen peroxide. Nitrous oxide, is a colorless, nontoxic gas, in fact it is used as a dental anesthetic. N2O4 is a reddish gas which is highly reactive, corrosive, and toxic. It would also be reasonable to refer to the compounds in smog as "nitrogen oxides", if you prefer. Please correct this.
Who on earth dislikes this? Was it because she said Glasgow weird? I don't understand!
The Austrailians are liking the video

Thank you Mrs. Preshoff for your wonderful contributions.
Ms. Preshoff, I am glad that your gift for passing along concepts and information in interesting manner has been widely enjoyed by the world through Ted-ed. It is obvious that you find educating to be a deep purpose and calling in your life, and I am honoured to benefit from it even though I am half way across the world from you! Wishing you more recognition and acknowledgement all the way from India❤️

💟💖Kim Preshoff💕🎀
Loved the way she pronounced Glasgow
UniVoidz
This is the first comment in wich a person is happy for the way she pronounced that word. (😂😂😂)
I also liked the way she said that word!
UniVoidz it's just a shame it and Edinburgh were pronounced completely the wrong way.
thanks Kim for giving your precious time to us, and teaching us
Thank you Kim - right to the point.
Koffing, use smog attack!

Nice work, Kim, looking forward to seeing more from you!
Firstly, thank you Kim. Delighted to know such teachers are still there😊. Secondly, thank you Ted Ed for supporting such initiatives, and making the learnings of these teachers available to us. Thirdly, amazing animation, as always.
1:21 who also thought it was a cow at first? xD
umm it's a cow
But, it IS a cow
Oh, nvm, it's a bull because it has horns, but it's also genderless, because it has udders and horns
cows do have horns
He meant who thought that it was the cow which causes the mentioned kind of pollution.
I am slightly annoyed at the way she pronounced Edinburgh and Glasgow it's Pronounced (Glas-Goh) and Edinburgh is pronounced (Edin-Bruh) not that difficult. Never even heard them be pronounced that way before.
mhmm i'm from edin and omggg
you Scots are so annoying
A big thank you to Mrs. Preshoff and TED-ED team for such wonderful resources.
Thank you Kim, this was an amazing lesson and very important to emphasize even today
*SMAUG* ... anyone get it?
the desolation of smog ? NO I don't get it
Incredible chanel☺.If you agree with me, give a thumbs up.
Thank you Kim! I wish I had a teacher like yourself growing up but I'm glad you've taught fantastic lessons (now internationally ).
The video is two years old and still it helped us gain knowledge in quarantine era
