Canine overpopulation

Because I live between a coffee shop and a park where people walk their dogs (in other words, take them to their toilet), I observe that the typical family these days has a man and a woman who either has two children or is pregnant with the first or second one – and … the dog – or two. And one of the humans is typically carrying a takeaway coffee cup – and often a phone.

From these observations, I conclude that from this (meaninglessly small sample) that human population growth is not a problem, but that dog population growth might be (because twenty years ago many fewer people had a dog) — and also that pollution from the needless use of non-reusable artefacts continues to increase.
