> The US seems to have no defense against invasive pests, plant, animal or insect, it just lets them spread.
A large portion of that is inevitably of the US's own doing through its love of intensive agriculture.
Liberal use of hormones and antibiotics in animals, liberal use of pesticides etc. etc.
Not saying no other country in the world uses antibiotics or pesticides, but the US does it more intensively and more extensively than almost any other country on the planet.
You then end up having to fight fire with fire as things build up resistance.
