Where have you gone?

Oh wonderous world
You hold on to so much beauty
As I sprout, I see bushes and leaves all around me
Platypus swim by a near river and koalas climb up toweing trees 
Leafy, green, lush, still
Oh wonderous world, you hold so much beaty

Oh cruel world
You are being taken away
I can only watch as one by one my friends drop like flies so that people can take over and make our rivers black
Polluted, destroyed, stolen, wrecked
Oh cruel world, you are being stolen

Oh destroyed world
You are in ruins
Now, massive structures touch the sky and shoot out harmful black smoke
I stand alone in all the chaos
Alone, destroyed, deserted, stolen
Oh destroyed world, where have you gone?
