This mess was not left behind by monkeys but by apes, Homo sapiens to be precise.
They don’t usually beg or harass, but they leave an awful mess behind. On early Sunday mornings, before the park cleaners get to the mess, you can see signs of their handiwork all over well frequented parks in Singapore. Despite the many bins.
I suspect most know how to use the bin, but there are enough who are untrained and cause the disproportionate mess.
It’s been five decades but this species is pretty resistant to learning. So the job isn’t over yet. I wonder what we should do.
