- How would you describe human population growth for the past 200 years. When determining Earth’s carrying capacity for humans, why is it not enough to just consider human numbers? What will happen if there is a rapid growth in human population? What solutions do you have in mind to limit the human population growth?Do you think there are environmental limits to human population growth? If so, how close do you think we are to such limits? Explain.What factors led to the dramatic decrease in population growth rates in Kerala, India?Compare the case of Kerala to India’s national population control program put intoplace in the 1970s.
- Why is the minimum viable population size smaller for a geneticallydiverse population than for a less genetically diverse population?How does the study of population ecology help us understand why some populations grow, some remain stable and others decline? The human population has grown as we have increased our global carrying capacity. In your opinion, can the global carrying capacity continue to increase/ Explain your answer? Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades?Mention any four probable reasons for the rapid rise of population in our country?
- What is an organism population that has had exponential growth, and what circumstances led to that exponential population growth?What would happen to the moose population if the wolves were removed from the island?

Identify 2 possible limiting factors that have influenced the wolf population?In the development of the exponential model of population growth, why can B and D be substituted by bN and dN, respectively? Explain.
- In a graph of population size versus time, a J-shaped curve is characteristic of (a) exponential population growth (b) logistic population growth (c) zero population growth (d) replacement-level fertility (e) population growth momentumExplain the difference between logistic and exponential population growth. What do these growth curves look like. Which represents human population growth over the last few thousand years?According to Worldometers, in late November, 2018, the U.S. population was 327,726,061 and the world population was estimated at 7,666,602,725. Considering those numbers, do you think the United States is in a population crisis? Do we have enough land and resources to support a continuous increase in population? Should we, as a nation, concentrate on controlling our population or controlling resource use? Why, or why not?
