A little light pollution

It had been a lovely evening,
All birdsong and soft light.

Now, it became the night;

Noisy with sirens in murky olive grey,
Punctuated by flashing blues and reds
And that malicious green that's
Quite untouched by nature.

I used to love the city,
Now I don't.
But with loss of love came indolence
And perhaps a little fear.
Would elsewhere be better?
