One example of an everyday use would be when you bake a loaf of bread, you rely on the chemical reaction of the yeast in order for the bread to rise. When you consider that even such small things as baking require chemistry, you can begin to understand how it impacts every aspect of life. The simple day to day things we all use that would not exist without chemistry include:
• Washing powders, liquids and detergents
• Fuels to make our cars, lorries, boats and airplanes go
• Insecticides and fertilizers for use on our farms
• Many different make ups, shampoos and shower gels require the use of chemicals
• Microchips in credit cards etc.
The role of chemistry is essential in the production of the above items which are all essential to life as we know it. Looking at chemistry from another perspective we have the development of medicines; again imperative to everyday life, as without the continual development of new medications life would be very difficult indeed.
As a society, we expect chemists are doing all they can to investigate new combinations of drugs and chemicals to treat disease and illnesses. Without this role of chemistry, our expected life span would be greatly reduced and hundreds of thousands of people would die each year through untreatable illness.
