When I first moved to Bali, now almost 18 years ago, the one thing that I found most unappealing was the proliferation of trash to be found almost everywhere. And by everywhere, I mean, everywhere, from within the ditches that line every road, to most all of Bali's beaches.
A great deal has been done to eradicate this problem, and a lot more needs to be done, but without question I would have to say that Bali today is far more beautiful and with less trash about than as I remember from years ago.
The reasons for this improvement are many, and this link below is just one small example of how the locals themselves are taking action to keep Bali green, and beautiful.
