Reaching heights of over 100 meters, Californian sequoias tower over Earth’s other 60,000 tree species. But even these behemoths seem to have their limits: no sequoia on record has been able to grow taller than 130 meters. So what exactly is stopping these trees from growing taller, forever? Together with Doug Alberts, a talented motion designer, I created this TED-Ed to answer this burning question.

Since the English version of the animation has been very popular, gathering over 1 million views on Youtube, it has also been translated into German, Spanish, Japanese, Hindu, Mandarin.
