Moreover, who cares about a hairy army of junk-food loving bears stumbling around the woods of northern Wisconsin? Mainly, the research highlights the degree to which humans cause some wildlife populations to rely on them for food. If killing and scavenging is the bear equivalent to cooking meals, and eating bait is ordering delivery, then bears are ordering in every night of the week, and on some days they’re even ordering lunch.

As petroleum price is expected to increase in the future due to oil production decline and increases in global demand, the cost difference in favor of PEVs is expected to become even more advantageous.
