BIOLOGY DISCUSSION

INCLUDE A REFERENCE AND W/C OVER 250

1. Take a look at the World POPClock  where you can compare the ever changing world population with years gone by. The current world population is over 7 billion people. Do you believe that the U.S. should be concerned about overpopulation and that immediate action is warranted, or do you believe that the risks of overpopulation have been grossly overstated? What about other parts of the world? List at least one source from your research.
2. Review this website. Research the Internet about the different ecosystems. For your first post, write a description about the particular ecosystem that you live in. What is the ecosystem? What is the climate like? What type of vegetation is there? What is the temperature like? Etc? Your answers should reflect your own observations about your surroundings as well as those found on websites. List at least one source from your research.
3. Everything we do on this planet leaves a mark.  An ecological footprint is the degree of human impact on our ecosystems.  Americans are at the top of the list for their detrimental footprints on our ever increasing fragile planet.  Take the quiz on the following website: Ecological Footprint Quiz.  Share with the class your results.  How does your personal footprint compare to others in America or others around the world?  Do you personally do things which should help to lessen your footprint?  Have you within recent years changed your habits or actions to help the planet?  Do you think that global warming and destruction of our planet is really severe or do you think it is all public hype?  Are the Earth’s forests disappearing?  Does it matter if they are?  Is there any hope for our planet?  What are your suggestions or concerns? List at least one source from your research.
