it’s a jungle out there meaning

It’s a jungle out there Disorder and confusion everywhereNo one seems to care
Well I do
Hey, who’s in charge here?
It’s a jungle out there
Poison in the very air we breathe
Do you know what’s in the water that you drink?
Well I do, and it’s amazing
People think I’m crazy, ’cause I worry all the time
If you paid attention, you’d be worried too
You better pay attention
Or this world we love so much might just kill you
I could be wrong now, but I don’t think so!
‘Cause there’s a jungle out there.
It’s a jungle out there.
