The principles of chemistry have been modified over time and are still evolving. At the dawn of human experience, our ancestors survived through knowledge acquired by trial and error which types of stone were hard enough to shape others, which plants were edible, and so forth. Today, the science of chemistry, with its powerful quantitative theories, helps us understand the essential nature of materials to make better use of them and create new ones specialized drugs, advanced composites, synthetic polymers, and countless other new materials (Figure 1.4, on the next page). 

Several different plants have been used for the expression of proteins in plants. All these systems have certain advantages regarding edibility, growth rate, scalability, gene-to-protein time, yield, downstream processing, ease of use, and so on, which I will not discuss in further detail here. A selection of different expression systems is listed on the next page ... 

The news media reinforcement is subtle in misconceptions on risk of chemical plants. They provide selected news coverage. No doubt there are many poor unfortunates in southwestern Louisiana who die harvesting shrimp, oysters, blue crabs, pogy fish, and edible fish. Their demise is not a top story. No news reporter takes a photo of the water or the boat that steals the hard worker s life. Or in the case of the timber cutter who perished, no one takes a photo of the tree that struck the deceased or a photo of the chain saw that was involved in the tragic accident. These incidents usually appear in the back of the paper, or only the worker s name, age, next of kin, and personal information get published on the obituary page.
