do you think the global population of 7.1 billion is to too large? Explain. If your answer was yes, what do you think should be done to slow human population growth? if your answer was no, do you believe that there is a population sizethat would be too big? explain. do you think that the population of the country where you live is too large? explain.
The human population was 6.0 billion in 1999 and has been growing ~ exponentially with an intrinsic rate of increase of 0.007. How many people could there be 100 years later (2099), if that trend continues? [e = 2.7183 ]

- 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?arrow_forwardWhich country looks like it is experiencing exponential growth?
