I pick up small items of plastic on 'my' beach all the time thinking of fish and animals who swallow shiny colourful things and die. Plastic seems to me to be one of the biggest scourges of invention. So useful and so dire in consequence.
I have to say I don't like the f word used at all (cannot see the point) but the other two logos are excellent..........I'd wear them in a heart beat.
Well done.
