Organic

An organic product (e.g. food, clothing) is made without the use of synthetic chemicals. It is likely to be free of human made pesticides and chemical fertilizers. It does not disrupt the local ecology and is probably of local origin, e.g. Slow Food.

The label organic is variously defined. There is a range of audit procedures one might apply to determine what is "not organic". Factions make it impossible to settle on one strict and global definition, so this is a contested term - see glossary for other such contested terms.
