'Inside' the concrete 'control tower' of AMADEUS's base...a SCARLETT PINK straw and BROKEN GREEN GLASS - as well as a ubiquitous pile of leaves (bodies?)...what could it mean?

I might add that there were quite a few SCARLETT PINK and WHITE straws upon the bridge, this morning...as well as one YELLOW and WHITE one...or maybe more...i couldn't be bothered to count...the wind and rain will wash them all off...
