Some eco-terrorists want to buy some giant's hogsweed.
"Don't you know that it is poisonous?"
"Well why not go for some Japanese knotweed"
"Or what about some water hyacynth... clog up a canal in no time"
Eco-terrorists don't have the attention span of a gnat. They have been eating too many magic mushrooms. They wander off to look at terricotta flowerpots.
They left with nothing... their brains as fluid as super refined sewing machine oil.
