Discussion Questions-Chapter 7 1. Suppose that you were engaged in biotechnology, or genetic engineering; what environmental safeguards would you impose on your research? Are there experiments that would be ethically off-limits for you? - In biotechnology and genetic engineering research there are many limitations if you consider the environmental aspect. But sometimes or practically many times it cannot be avoided. For example, the use of radioactivity- The radioactive probes are mostly used to detect specific molecule or gene in the cell system which gives highly promising results. But there is an alternative for this also such as chemical probes to avoid the problems caused by radioactivity. There are many reagents used in biotech or cloning experiment which are carcinogenetic. To avoid its lethal effect to living creatures, you have to follow good lab practices, and the disposal of the waste generated should be properly managed. 2. Debate the claim that famines are caused more by human actions (or inactions) than by environmental forces. What scientific evidence would you need to have to settle this question? What hypotheses could you test to help resolve the debate? - Famines can be caused by many things, human influenced or not; unannounced severe weather changes, rototilling your land too much, fire etc. But human actions almost always work with environmental factors. The potato famine was brought on by Irish farmers who farmed nearly exclusively a type of potato that was susceptible to blight. They were overly dependent on it and failed to diversify. Your question didn't exclude some natural influence as well. Most famines such as the recent ones in Africa were due to war lords keeping food from those they didn't want to feed. Suggestions that it was caused by drought misses the point. Droughts have been happening throughout history and used to be much more influential in causing starvation. Now, with our modern transportation and high technology, famines are far less common and are almost always political in nature. 5.
