Existence!

It’s scorching hot here,
On my deserted island,
Where the sun blazes all year!

My throat is just so dry,
I need a drink,
Cool droplets from the sky!

I need water it’s 60% of me,
Ocean water is on all sides,
Yes, a cool drink under a tree!

But to drink the ocean I’m unsure,
They say, you’re what you drink,
So make sure what you drink is pure!

To do that requires desalination,
Failure to remove the salt,
Will cause severe dehydration!

I need water to survive,
So a desalination kit,
Will keep me alive!
