Q: What one chemistry fact should every member of the public know?

A: All life is based on chemical matter and processes. Our body is made out of chemicals, and functions according to the principles of chemical reactivity, and chemistry greatly improves living conditions: without antibiotics and other powerful medicines created by chemists our life expectancy would be much reduced, without polymers and plastics, there might be no trees left on earth. Without chemistry, the world population of more than seven billion people could not be fed.

A: To some people, the word ’chemical’ has become synonymous with poison. But Joe (and Josephine) Public should know that all matter, animal, vegetable or mineral, is made up of chemicals.
