Oahu began a barren molten rock. So isn't every species an "invasive species"? 
So maybe media's endless focus on "help me government", help me, The World Is Ending and The Sky is Falling, is just aging boomers increasingly frightened by change as old people so often are  
Look at "The Climate is Changing" nonsense.  Of course it is you sillies. That's what climate has always done. Jurassic? 
Now want Insurance that mitigates the cost of medicine and medical treatment for illness and injury changed to "Health Care" like maintenance drugs to keep them alive despite sloth, overeating, and other health destroying pleasures of the life style to which they've been accustomed like wanting legal MJ. But hope springs eternal. For me it's that a new generation appears who, despite the declining education and indoctrination boomers have imposed since "Why Johnny Can't Read" (60's), figures out they are all growed up. And get back to remaking the Earth to their liking. Not cower in fear of change
