An Arbor Embolism Questions:

1. What is an embolism, as it pertains to humans?
The embolism that pertains to humans clogs the artery that stops the flow of blood from the blood vessel.
2. What is an embolism as it pertains to plants/trees?
An Embolism as it pertains to plants/trees is to have more and more gas accumulating in the plumbing system, until they can't get any water up into the leaves, when it suck water up from the ground all the way to their leaves.
 
3. What implication does this discovery have in terms of global concern?
The implication this discovery has on global concern is that droughts temperatures are rising around the globe, when drought dries out the soil, a tree has to suck harder. And that can actually be dangerous, because sucking harder increases the risk of drawing air bubbles into the tree's plumbing.

    1. For question number 1 isn't the answer for the embolism that pertains to human correct. In the 5th paragraph in the article it says that, Like a human embolism, the gas bubbles stop the flow of fluid. If that persists, it means thirst, starvation and eventually death. Isn't that what embolism is when it pertains to humans.

  3. 2:The leaves opens up a stomata which causes it to get all its carbon dioxide but loses water. Then causing it suck more water from the ground. Making air bubbles clogging the system. Causing it to die. :)
