about the giant sequoia trees is how long they can live a thousand two

being such large organisms may make them
being such large organisms may make them more vulnerable as the planet warms and

if there’s less water available we’ve
if there’s less water available we’ve found on a typical summer day that these
found on a typical summer day that these
found on a typical summer day that these trees can use two to three thousand
trees can use two to three thousand
trees can use two to three thousand liters of water in a single day and
liters of water in a single day and
liters of water in a single day and that’s an enormous amount of water
that’s an enormous amount of water
that’s an enormous amount of water especially when you take into a context
