Chapter Questions - Week 3 Chapter 7: Discussion Questions 1, 2 and 5. 1. Suppose you were engaged with biotechnology, or genetic engineering? What environmental safeguards would you impose on your own 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 that claim that famines are caused more by human actions (or in actions than by environmental forces. What scientific evidence would you need to have to settle these questions? 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 to rototilling your land too much to fire to et cetera. To draw up a thesis to these question(s) you would need: -To chooses a specific crop (because lettuces fair differently than potatoes) -Get weather records for the past odd years -Find specific agricultural locations (specific as in same land structure, same elevation, same sort of climate, and et cetera) or develop an indoor agriculture working mock up. -Choose the months or stage of agriculture you want to see effected by human or environmental forces -Develop a controlled test group, an influenced test group, and stable test group. (i.e. one that deals with weather occurrences and changes, one that deals with average weather and human
