Community efforts to eradicate Albizia?

"And I appreciate that many people are concerned about herbicides, but a drop or two of Milestone near the Albizias along the highway is a drop in the bucket compared to oil, gas, and whatever else routinely drips out of all the cars every day along the highway."

without at least referencing some sort of data to go on, it seems a bit hasty to be so confidently contrasting any environmental side effects of this Milestone herbicide as "absolutely" "a drop in the bucket" compared to leaking auto fluids. same goes for claims of any unusual dangers associated with the herbicide.
