Recently, I was in conversation with a couple of people here in Tutukaka. The topic was the local tourist map which I produce and pay for with a series of small advertisements. I was asking them to advertise their business. One of them said she was not happy to do so since the tourist map was not environmentally friendly. My eyebrows went up, and I pointed out that the map was on card board, which was biodegradable. She agreed, but said her problem was the ink which was full of chemicals. Again, my eyebrows went up, and I suggested that everything was full of chemicals, including the human body. She disagreed vociferously. Only synthetic evil products contained chemicals.

A knockout blow for evolution turns out to be nothing of the sort

The Swedish chemist Berzelius coined the term "organic" for substances that could only be made by living organisms and not synthesised by humans. His German friend Wöhler synthesised urea in 1828 proving Berzelius wrong: there was no such distinction. Another brilliant German chemist, Liebig, then used "organic" to mean carbon-compound chemistry, extending this to include the chemistry of living organisms and so beginning biochemistry.

One of the fictions of the "naive-greens" and other "irrationalists" is that "chemicals" are bad while natural products (non-chemicals?) are good. When asked if water is a chemical, and hence evil, and whether cyanide, nicotine or the botulism toxin, are natural and hence benign they change the subject. You might think that our classrooms are immune to such nonsense; in the November issue of Chemistry in New Zealand, Ian Millar of Carina Chemical Laboratories Ltd tells us we are wrong.

Despite recent claims that "natural" foods are safer, there is evidence that "natural" pesticides can be present at much higher concentrations than residues from synthetic pesticides. These "natural" chemicals are often untested and of unknown toxicity, with little evidence of health benefits.
