You shouldn't judge a book by its cover, and you shouldn't judge a species by place of its origin, so say ecologists in the commentary in the Journal Nature. They argued that conservation should access organisms based on their impact on the local environment rather than simply whether they are native,
when you hear the phase non-native species, you no debt conjure1 up an image of invasive animal or plant that
pushing out the native species and wreaking2 havoc3 on local ecology, like zebra mussels on great lakes, or K in Australia.
But Mark Davis of M college in M(M college), see things differently . They say being indigenous4 doesn't grant a species special right to inhabit in the Eco-system,
or mean that it's presence is good for the environment. The insect currently thought to kill more trees than any other America, is the native Mountain pine beetle5,
and many invaders6 actually boost biodiversity, not decimated it.
As the climate change and urbanization continue to reshape the ecological7 landscape, more species were leaved their homelands,
making the distinction between resident and alien a moot8 point, so ask not where a species comes from, but where it belongs.
