Describe the plant life, animal life, and geology of the ecosystem in the area in which you live. What populations and communities are present? How dependent is your community on this ecosystem? What are the limiting factors of the ecosystem?


If I can get this on wednesday I would be greatful

The current worldwide population is 6,775,235,700 (World Bank 2011). This number is XXXXX moment-to moment, day-to-day, and from one year to the next. Interestingly, the rate of birth for many countries is declining due to economic disparity and an increase in education and conceptive use. When looking at a plot of year vs population size an increase is very evident, but the slop of the line is less dramatic in recent years as compared to the mid 1900s. The human population is extremely high and there is not enough room on this planet to sustain the population at it’s current growth rate. All of our ecosystems are being stressed via anthropogenic impact, urban sprawl and environmental degradation. Our resources are not being used sustainably and our ecosystems are being abused. A prime example is the amount of logging taking place worldwide, particularly Mahogany in the Amazon rainforest. It is there that old growth forest is being logged and shipped globally. In the process many animals are losing their homes and going extinct, while the decline of trees means an increase in greenhouse gas emissions. Furthermore, pollution from the machines that are logging the forest is amplifying the environmental issues the Amazon faces (WRM 2001). We must get the world on the conservation and sustainability bandwagons!

I live in a tropical ecosystem. The plant life is mainly palm trees, pine scrub, and river grass. There are many types of animals. Some of the most abundant are birds, fish, alligators and snakes. The geology of the region that I live in is mainly limestone. I am almost at sea level so there is very little ground depth that is primarily limestone and of course mixed sand. There are numerous populations of bald eagles, alligators, raccoons, cattle egrets, and herons in the area in which I live. There are numerous terrestrial and marine communities, which cover tropic biomes. My community is highly dependent on this ecosystem because not only does it provide of us with fertile land for agriculture, but also it is a region prone to heavy traffic from visitors and vacation goers. Many people flock to the beaches, small off shore islands (Keys) and the Everglades. The limiting factors of my ecosystem are water and temperature. If water is unavailable all forms of life begin to take a toll, and the transfer of nutrients form one part of the system to the next cannot occur. Moreover, the organisms in my ecosystem prefer warm-humid temperatures and do not function well at colder-drier temperatures. Another limiting factor are visitors and resident development. The ecosystem is quickly being degraded by anthropogenic factors, and we need better regulation to insure this does not continue. I truly enjoy living in this tropic ecosystem and wish for it to be conserved properly. Please click the green button so I receive credit for my work.

  • 1. Capstone Checkpoint


  • You have read about Earth's numerous ecosystems and the biological diversity that inhabits them. Unfortunately, many of these habitats and the species that inhabit them are under threat from human encroachment through agricultural activities such as logging, pollution, or war.


  • Post a 200- to 300-word response to the following questions:


  • o What role, if any, do you think people should play in preserving those regions threatened by human encroachment?
  • o How should the interests of competing groups be balanced?


  • Example: Drilling in the Arctic-environmental groups oppose the plan on the grounds of the destruction to the habitat; those in favor argue that tapping into the oil there would be good for the economy and decrease reliance on foreign oil.


  • o What about when the habitat is not within the U.S. borders? Many international conservation groups are working to save the rainforest-what rights do people have to interfere with how another sovereign nation chooses to manage its lands? If the government of Bolivia is willing to allow millions of acres of jungle to be destroyed to promote the logging industry (which provides employment to their citizens), should people intervene? Why or why not?


  • 2. Final Project: UNESCO Paper on the Simien National Park


  • Resource: Appendix A
  • Write a 1,400- to 1,750-word paper assessing the ecological property you chose for your final paper. Identify the ecological uniqueness of the plant and animal life in your chosen property and address the following:


  • o Describe the diversity of life forms found in the area.
  • o Describe the biological interrelationships among the life forms in the area.
  • o The human intrusions threatening the area.
  • o The protections that exist to safeguard and preserve the area.
  • o The efforts that have been made to further this preservation.
  • o What an individual can do to help preserve the diversity of the area.
  • o What additional measures to insure the preservation of the property would you propose?
  • o What will be lost if intrusion goes unchecked? Appeal to the biological diversity.


  • Format your paper, in-text citations, and references according to APA standards.
  • Post your paper as a Microsoft® Word attachment.
