It's own-back time

I'm so worried about the way we are damaging the planet and feel quite impotent about doing anything much to reverse the ruin we are creating. I wrote the following last year, after we had had that terrible sunami, the hurricanes and floods and other natural disasters. I imagined that the Earth was getting her own back - and more power to her elbow, I say.

REVENGE
Turn again, turn again, turn Mother Earth.
Planet of loveliness gone down the drain.
Soon - world of pestilence, mutated birth,
Strontium 90 and foul acid rain.
No ozone layer - the pastures will burn,
No birds will fly or fish swim in the sea,
The forests and woods will die in their turn;
Mankind has gone on a merciless spree.
We’ve played with genetics, 'meaning no harm',
We’ve poisoned the oceans with all our waste.
No flowers, no crops, no bees in a swarm,
We’ve ruined it all in our ravenous haste.
Get rid of our greed which holds you in thrall.
Turn again Gaia, get rid of us all.
