Discuss the themes of Environmental Science in Today's World. Describe the demographic transitions that are influencing family size.
Human populations continue to grow worldwide. Using selected countries as examples, you have been asked to prepare a short report for a conference about the consequences of continued human population growth on a global scale.
Please answer the following questions in your post:
* What types of information or data would you need to prepare for a report on this issue?
* What topics would you include in the report? Why do you feel these issues are important or relevant to the consequences of increased human population growth?
* Which countries might you select to include in the report? Why did you make these choices?
* Would you include information about where these countries are in regards to the demographic transition? Why or why not?

Any intro environmental science book will list population growth and/or poverty as the number 1 & 2 environmental problems. Quite simply more people use more "stuff." As the developing nations strive to go from "have-not" to "have" (or at least "want"), then net consumption rises. Per capita income is a fair equator for growth.

Pollution too, tends to be a "waste item", that is if it isn't used it's waste. If all processes were 100% efficient, then not worries - however, none are.
Hence pollution = inefficiency!

One thing I would be tempted to look at is the increasing gap between the "have" and have not" countries with respect to energy use, and caloric intake. The US (5% of world ppl) uses 25% of the energy output. Doesn't take a math wiz to figure out the Earth cannot support 6 billion Americans. Furthermore, There is an energy boundary that population will run up against one day. There is only so much sunlight to ; drive the hydrologic cycles, cause plant growth, sponsor winds, etc. Likewise there is only so much land (and of that, only so much "viable" land. If we measure the land, measure the sun and the rate plants "create" biomass - then we can estimate a gross sustainable population of the planet. Its not as big you'd think! (about 5 billion)

Environmental Science #2
I need assistance with a project concerning demographic transition, which is little confusing to me. I am really concerned with this class as I have a failing grade. Any and all of your assistance will be greatly appreciated. I really need your help with this assignment
Not all countries have moved through all four phases of the demographic transition. You are a consultant for a developing country that is not yet in phase IV of demographic transition.
In your own words, complete the following:
Define demographic transition.
Describe the 4 phases of demographic transition, including if the population is stable, growing, or declining in each. ·
According to demographers, what factors lead to a decline in the crude birth rates (CBR) and crude death rates (CDR) in the epidemiologic and fertility phases of the demographic transition? ·
Briefly describe three living conditions and/or environmental impacts in developed countries that have reached phase IV, and contrast them with these conditions or impacts in developing countries that remain in earlier phases. ·
Assuming that the demographic transition phase IV is a goal for developing countries, what two programs or initiatives would you suggest to assist them in progress toward this goal?
