Chemistry is the study of all chemical substances and how to change one chemical into another. The food you eat, the air you breathe, your own body, your mobile phone, the plants and streets around you are all made of chemicals. As you want inexpensive products, chemistry helps to decrease economic costs. As you want a safe environment, chemistry helps to decrease pollution by detecting the toxins, and by destroying them. Gone are the days when poisonous red lead oxide was used to colour cheese, or to sweeten cider; and now we do not put toxic arsenic in cosmetics, nor do we use lead in white paint, or make CFCs that destroy the ozone layer. These chemicals were used mostly out of ignorance, so with the development of new understanding in chemistry a safer world is built.
