Multiple Choice

Define linear and exponential growth. Do human beings exhibit linear or exponential growth? What is the implication of this growth pattern?

If the population in each generation increases by a constant multiple and if, for example, it doubles in each generation, this is called exponential growth. it can also be said that exponential growth results in unchecked growth due to its faster growth. While linear growth occurs at a constant rate. Human growth exhibits an exponential growth model as it is evident that the population has always been increasing from its initial value. It can be inferred that as time passes by, resources will be a limiting factor.

2. Define the Scientific Method and Informed Decision Making. What are the advantages and disadvantages of each? Which method do we use to make decisions regarding environmental issues?

The scientific method is a process for experimentation that is used to explore observations and answer questions based on it. The great advantage of the scientific method is that it is unprejudiced and it does not need any super human powers. Disadvantage is that it lacks ecological validity and it uses quantitative data rather than qualitative data. Another disadvantage is that the mastering of the techniques requires time

In informed decision making process a major part of decision making involves the analysis of a finite set of alternatives described in terms of some evaluative criteria. These criteria may be benefit or cost in nature.

Advantage include that the decision is made only with the consent of the subject involved. Disadvantage is that the so derived decision can go wrong.
