From Dyane Silvester, Arnside, Cumbria, UK
It is very refreshing to read Sophie Attwood’s comments around the (often unwarranted) assumption that “natural” materials are automatically better than “modified” or “synthetic” versions. My response to people telling me that something is “totally natural” in this context has always been: “So is arsenic, but it’s still going to kill you(30 August, p 19).”
