What are the potential hazards of electric wires near trees?

The potential hazards of electric wires near trees primarily relate to the risk of electrocution if tree branches come into contact with these wires. Trees naturally grow and their branches may extend into the vicinity of overhead electrical lines. If branches make contact with the wires, there could be a conductive path for electricity, creating a serious hazard to both the tree and any nearby individuals. This contact can lead to electrical shocks or fires, underlining the importance of maintaining safe distances between trees and power lines to mitigate these risks.

While the other options mention possible scenarios, they do not correspond to the direct and immediate hazards presented by electrical wires. For instance, the impact on tree growth is not as significant in the context of safety compared to the danger of electrocution. Similarly, while insects may be attracted to various factors in a tree, this is not a direct hazard posed by proximity to electric wires. The idea that electric wires provide support to trees is misleading; they do not serve any structural purpose for the tree and often present risks instead. This makes the identification of electrocution risk as the correct answer clear and pertinent.
