Cemetery
After more then 200 years of industrial revolution and growth, the human economy has come to threaten the workings of nature and has put long-term survivorship and demography in great danger. Globally, the world is witnessing unprecedented changes in population structure. Questions arise about environmental problems getting worse, population related diseases increasing, if AIDS continues to increase and no cure is found what happens and if Medical advances continue will most diseases and infant mortality be eliminated is the world going to be O.K.?Nature has its own economy, a complex system of exchange, competition and cooperation. In many ways, nature's economy is like our economy. For example, the economy of nature contains producers and consumers and avenues of exchange between them, food chains and webs (Chiras, 1995). But lest we forget, the human economy is really only the smaller economy in nature. The human economy is possible only because of nature. All food and materials come from the soil, water, air, and biota. Ultimately, our wealth is derived from earth.Unfortunately, the human economy has grown so dramatically that it is destroying the larger economy that powers it says Chiras, 1995. After
ResultsThe following are the results of class data on cohorts between the years 1840 and 1899 Figure 1: Shows the survivorship between the different cohorts. Demography is the study of the internal composition of populations and the effects of that composition on the population growth (Microsoft Encarta 2000). One species whose fertility and survivorship is affected by age is humans (Homo sapiens). We should watch! for more catastrophic and new epidemics that are near before the graph really changes. Figure 3: Shows information on the survivorship of men versus women. Human survivorship fits the Type 1 curve in that most humans live a healthy and for the most part a safe life. With all the medical advances and technology today AIDS is not the only disease process that we should watch for. com c 1997-2000 Microsoft Corporation. We risk upsetting it at our own capacity. This works out at about 8,500 a day - 7,500 in adults and 1,000 in children. UNAIDS (1996) Global estimates of the HIV/AIDS epidemic. This figure shows us that the age of death will increase over time dependent on conditions such as food, water, shelter, general health, and safety. Between 1850 and 1890 survivorship increases. A Type 1-curve shows that there is low initial mortality and many individuals are going to live to an older age.
