We CAN change it, but better still, we can make sure it doesn't happen on rivers.
You know, when this argument surfaces (about once a month) I always get accused of being a sentimentalist (guilty as charged) and not having one scientific fact to back my argument (guilty as charged.)
I've never argued for the closed season on those platforms. I've been through 25-odd closed seasons in my lifetime, and what I remember best is the sense of occasion when the season opened - the anticipation, the planning, all the things I enjoyed about it.
So I what I want is for everyone to enjoy the same things I love, I want some fun in fishing, and there's nothing wrong with a bit of self-denial every now and then. It enhances the pleasure and creates a sense of occasion.
I have absolutely no time for anyone with the 'move on' argument. It's facile, lazy, lame and meaningless. You don't like something, you complain. Nobody listens, you demonstrate. Protest IS civilisation.
