But it gives me some satisfaction to think that over the years I've tidied up a small mountain of rubbish to allow the sunshine and shadows to play seductively on fairways adorned with nothing but grass. That way, no matter where I finish in my foursome, I've still cleaned up on the course.
And if I just walked past, averting my gaze? Well, the park would soon resemble the Ogden Nash poem:
I think that I shall never see
A billboard lovely as a tree.
Indeed, unless the billboards fall
I'll never see a tree at all.
Maybe it's time to try the profit motive. If people won't tidy on civic-minded principle, perhaps they will for money. But our government or councils don't offer that inducement.
New Zealand officialdom doesn't seem interested in requiring a mandatory deposit on containers to encourage their return by consumers. It's not like that in Australia, most of Scandinavia, and a number of US states, to name a few.
And we don't have reverse vending machines - a device accepting empty beverage containers and returning cash to the user, as in Germany, for example. That's probably because of lobbying here by the beverage industry, which doesn't want its sales diminished because of an extra charge at point of sale.
Maybe the beverage industry has got it wrong. We Kiwis might in fact be more willing to buy the beverages of those manufacturers who are prepared to chance their arm for the environment's sake. And the heftier the charge the better. How about a dollar a bottle or can? That would see fewer such containers lying around trees or beaches. They might in fact be a blessed rarity. And our choice of a beverage priced in a way that will pretty well ensure its container will be responsibly returned for reuse or recycling would proclaim each user an eco hero.
In the meantime, let's applaud those admirable initiatives or organisations which are out there, getting rid of the stuff which too many of us toss blithely away to blight our land and marine environment: Project Jonah, Sustainable Coastlines, EcoEvents NZ, the Herald on Sunday's Beach Busters campaign, and many more, including the Watercare Harbour Clean-Up Trust.
Sponsored by Watercare, the trust works year-round to clean up litter from the Waitemata and Manukau Harbour waterways. Since 2002, its boats have removed almost 30 million individual pieces of litter. It makes my 15,000 bottles and cans seem positively paltry.
Never mind. I'm still going to tidy up on strolls and during my golf games - even if my swing remains as much a highway under construction as ever.
