I wrote this poem. What could this poem be about ?

  

As I walk along this lonely beach

I hear the echo of a jungle tree

Or is it a parrot that tried to scream

Or the unknown shadows of a long dead beach

Was there a jungle to the left of me

Or just dead tree trunks that tried to flee

The sun is dimmer than it used to be

When and where can I now be

Is this the Earth I left behind

In the year 2029

There is nothing here for me to find

How could fate be so unkind
