vue - The chemical reaction that feeds the world - Daniel D. Dulek
View full lesson: http://ed.ted.com/lessons/the-chemical-reaction-that-feeds-the-world-daniel-d-dulek How do we grow crops quickly enough to feed the Earth's billions? It's called the Haber process, which turns the nitrogen in the air into ammonia, easily converted in soil to the nitrate plants need to survive. Though it has increased food supply worldwide, the Haber process has also taken an unforeseen toll on the environment. Daniel D. Dulek delves into the chemistry and consequences. Lesson by Daniel D. Dulek, animation by Uphill Downhill.

Chemicals Iz BAAAD!

Actually, Haber had no intent on feeding the world's population. He developed a method of synthesizing ammonium to create explosive weapons for Germany.

As with music everything resonates to a frequency, just as a crystal radio picks up on vibrations , so do plants.

Yet Africa is not fed, what are you talking about?

I'm hungry now!!! 😫

This video is amazing ..... thank you <3
-
watching this before my final chemistry exam really helped
-
Your videos are very informative, helpful and fun to learn with outstanding visuals!

como quebrar a amônia?
-
Transformar amônia em combustível parece agora razoável..
-
Very helpful
-
Thnx a lot!!! Really helped!
-
why does anybody give this video a down-vote? i mean... it's pretty much perfect!
-
VERY VERY INTERSTING AND DISCRIPTIVE

Dude, 1 2 3 You Rock ! Awesomely Boomed My Mind Within JUST A Flick ? I Directly Learned Each & Every Step Showned :) :P
-
Thing is, Haber didn't develop this way of making nitrate for crops, he made it to be used in gunpowder for Germany during WWI.
-
Extremely informative. Thanks :)

this video is awesome it explained what the harbour process was to me so clearly
