Need help making a line less cheesy!

Hello, guys! In one of my songs there's this verse:

"Your values are worthless
You parasite on the last
Alive edge of the universe"

And I think that the last two lines do not sound right. Maybe you could suggest some changes.
(the idea of this verse is critique of mankind spending it's days worrying about things that do not matter and destroying it's environment)

Thanks for help!

how about...

i close my eyes and cry, your values are worthless
like a parasite, i wander and wonder are you alive
am i dreaming on the edge, is this universe dead
mankind can try, but earth will fly, leaving us alone in the wind

hope that helps brother it s the best i could do on the fly

Your so called values are so damn worthless
Your callous actions just plain thoughtless
You're nothing but human locust
Your golden days have turned to rust
And things will change from bad to worse
Drifting across the universe

Just an idea. Hope it makes sense.

I'm assuming you're fine with the lyrics being a little heavy given the topic.

Values as worthless as the thoughts put into them
Let what's rotten remain rotten
Slowly eating away at the chances of survival
A trivial choice and a forgotten memorial

But worry not, for fresh air is only a grasp away
Cast out the fear of things you can't anticipate

I threw in the last two lines as a possible pre-chorus.
