It was primarily because of the combination of ecological and economic costs that are so well documented from the eastern regions of North America where the infestation has been going on for decades. It's very well known what those impacts are. It's also well known that infestation is moving in our direction quite steadily. It's not fast, but it's happening. The risk is high and the actual costs are also known to be extremely high. The combination of those factors just makes it a top priority for us.
