Fiction Adaptation - When Will the Forest Speak?

Here is one of the poems I am considering for my adaptation project.
It is called 'When Will the Forest Speak?' by the band Sikth.

Why can I not sleep?Why am I turning?Why are all the trees burning?Forest fires, crooked liars,Why am I so sullen and drained?
In the bush, it's raining,Lost man on his own,Has anyone thought to save him?
The monkey is waiting in the treeCounts to threeHearing the sound of the fume-fuelled wagonHe leaps on the back...Attack! Attack! Attack!No old heathen, not today.
The rain falls upon the acidic trees of the millennium scornThe fire has vanished, leaving behind a trail of death for all to see.The birds & the trees, then you & meLay twitching on the forest floor.The yeti is waiting for us to take us into his home,Care for us just like one of his own.
Wild bones!Wild bones!
Wait! The yeti no longer has a homeThe trees are gone & nothing has grown.A table, a chair, an internet nightmare,When will the forest speak?When all is dried up and way too weak?
Wait for nightfall, it's so beautiful out here.Up high in a wave of oxygen love I sit,Up high on this glorified cement postcard I spit.I spit, I spit upon thee.
Wait for your red skies,Wait for the red skies,Do you know how it feels to be alive?Let me know, let me know how you feel...When will the forest speak?When the trees are dried up and way too weak?
Wasting a life on calculations,Not enough money for operations,Waste of life, statistics, plastic soldiersSound of sticks rubbing together.All the people gather.
Wait for the man, he must have a plan,Show me and make me a smile I can wear.Me & you we can make up too,No use for hate if you're wearing my shoes.
Be happy, be sad, be a wild rotten lamb,Don't bother me now, I'm drenched to the bone.
A sound of a truck and an axe and a fallOf a tree and a life and a planet so smallSick to the bone of your dour heart of stone.Let me know how you feel...
You say it's too hot so you can take off your topA clank of a slot machine, coins bled unclean.
A beaten old lizard staggers over the road,A hand and a heart, the lake in the park,The candle won't light and the fire won't spark.
I'm worn and I'm torn but I still carry on.The money is angry, the money has taken the...
Watching mayhem leaping from truck to truck,This is where he rejoins his friends.They feast, they drink, they talk aboutHow things used to be...
I still can't sleep.I still can't sleep.I still can't sleep.
A million minds and a million voicesA million thoughts, and only one choice.The need to find peace.

When analysing the lyrics it is clearly about how mankind is slowly destroying wildlife and our land and nature. The title in itself 'When will the forest speak?' can be seen as, when will we take a stand and notice what we are doing to our environment. The audio itself for this poem is very disturbing, no music is used, just vocals, and strange voices, giving a very creepy element and tone to it, despite the poem having sort of 'noble' undertones, speaking out about the destruction of our environment. I feel if I were to do this poem, I would use the original audio, but of course do a lot of sound editing to set the atmosphere better to what I have envisioned.
My first instinctive idea, would be to have humans representing the different animals mentioned in it, but have them looking worn, tired and sullen, maybe even half dead, representing the environment being destroyed. There are however a lot of different messages and meanings given within the poem. I need to take the time to analyse the poem more and work out exactly what I can do with it, but I believe I have an interesting and unique starting point.
