I find it interesting that the term "invasive" is typically defined as
"showing harm."

There is an alternative (and more accurate) definition (from Wikipedia):
Sometimes the term is used to describe a non-native or introduced species
that has become widespread.  However, not every introduced species has
adverse effects on the environment. A nonadverse example is the common
goldfish (Carassius auratus), which is found throughout the United States,
but rarely achieves high densities.
