The advantages of chemisty are so many that it's impossible to give more than a brief outline: Almost *all* medicines were discovered by *chemists*, not by physicians. (The latter are merely practicianers.) Food safety is dependent upon chemistry. Without chlorine (a chemical) water supplies would give typus rather than quench thirsts. Modern life, as we know it, could not exist without chemistry. Chemistry is the basis of *all* sciences. The disadvantages are based on one factor alone: Too many people are science illiterate and *misuse* chemicals. Chemistry has so many uses in our daily lives that we could barely survive without it. Chemistry knowledge and methods are used to make: Detergents, Drugs and medicines, Textiles, Dyes and pigments and Fertilisers, to name only a few products.

A major disadvantage of chemistry is that matter changes when it comes into contact with another. Mostly we use that quality to an advantage--such as drugs, converting elements into energy, food, cleaners and so on. Sometimes, though, the elements can be used to wage war (chemical warfare, explosive devices) or may be accidentally mixed when used for a reasonable purpose. For example, using ammonia and clorine together has "gassed" many a housewife while cleaning.
