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 conjure 1 up an image of invasive animal or plant that

pushing out the native species and wreaking 2 havoc 3 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 indigenous 4 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 beetle 5,

and many invaders 6 actually boost biodiversity, not decimated it.




As the climate change and urbanization continue to reshape the ecological 7 landscape, more species were leaved their homelands,

making the distinction between resident and alien a moot 8 point, so ask not where a species comes from, but where it belongs.
