1. An embolism as it pertains to humans is a blockage that plugs up an artery in the body and slows or even stops blood flow to the area of body supplied by the artery. People might not be able to get the sufficient oxygen in their blood. It can cause blockages in blood vessels which disables blood to pass freely. They also may cause tissue to die if they prevent blood flow in a certain area. If it continues it leads to thirst, starvation, and eventually death.

2. An embolism as it pertains to plant/trees is when they have more and more gas accumulating in their bodies and they can't get enough water to their leaves when they pump or suck for it in their roots. It results in reducing photosynthesis and eventually leads to death. Also, when there is dry soil, the tree has to suck harder for water which increases the risk of drawing air bubbles into the tree's plumbing.

3. The implication this discovery has on global concern is that droughts temperatures are rising around the globe, which is making droughts more likely and intense. This can harm and effect plants by lack of water, too many air bubbles in their plumbing or embolism.
