It may be unfair to say such a thing, but it is a worrying environmental problem. Why are so many of Thailand’s canals like open sewers? And how can people live along them? This is Paknam Canal in Samut Prakan. The stench was overpowering. There is another canal the other side of town and the Thai nickname for this one translates as “stinky canal”. Surely something must be done about these canals. It cannot be healthy for families living along these canals. What can be done and how can we help?
