Sadly, this little canal in Adderley street is somewhat polluted. The general scene looks pretty enough, but on close inspection you'd see bits of plastic and paper drifting in the water, lodged in the trees, and strewn on the walkways.
Why are people so messy? Sure, Cape Town's wind doesn't help with this type of pollution - it's all too easy for papers and plastics to get blown out of people hands, or from their bags. If you drop a piece of paper when the wind's at it's best, there's no hope of retrieving it. But, it's often also the case that people have no sense for the environment and don't think twice before dumping their litter.
