"The oldest fiber"
Cotton's exact age is unknown. Scientists have found pieces of cotton cloth in caves in Mexico that are at least 7000 years old. It is one of the most popular fabrics in the world. It has been traditionally grown with mass use of pesticides, chemicals and water.
The chemicals used in conventional cotton production are some of the most harmful to humans. Every year, new chemicals are created to spray cotton crops as the cotton plant and insects that invade it grow immune to the current chemicals used.
Cotton is now being grown in certified organic fields, and in many cases it is processed in a manner to reduce environmental damage.
