Overindulgence

I'm suffering a little this morning and it's self-inflicted, so I cannot complain too much. I stopped the car on my way back from my Dad's place to Drogheda for what may be my earliest Blip ever.
These polytunnels in the fields are very striking and as I thought about them, I wondered if they're biodegradable. I'm no greenie but I'm conscious of how long it takes a plastic checkout bag to decompose. Food for thought!
