Down by the sea

I go to the beach,

hoping for sun,

I look in the water,

the coral is done,

What can I do?

How can I help?

I put my hand in the ocean,

all I pull out is kelp,

a turtle is swimming,

not far from shore,

In the corner of my eye,

I see something to adore,

not realising it's a plastic bag,

I try and pick it up,

before my mind would lag,

and when I do,

I lose my control,

when I notice a green thing eating it whole,

I try and stop the poor turtle's death,

but before you know it, a cute animal has left.
