ethical essay 4

Population taxation on resources is producing a strain on the world population that can not be ignored. Today, our world is under a tremendous strain to produce resources for our use and consumption. This is only going to get worse as more third world countries become more advanced, which in turn, will become more dependant on the worlds resources. We are beginning to really feel the strain with China. China and its vast population is becoming more dependant on commercialization. More people are able to afford vehicles. This has created a larger demand on oil. The news reports the negative issues with the demand of oil for the world consumption. This is not a "ripple", but rather a Tsunami. Even though China has a law regarding how many children a couple may have, this is not a solution that is working out. We as Americans, are just as dependant on oil as China. What was one of our solutions to the oil crisis in the 1970's? Lowering the speed limit. Did this help? I don't know. What i do know, is that we are in a crisis today. Is this because of oil speculators raising the cost of oil, or is because o population that has become a commuting 30miles one way to work in a gas guzzler society? I can't answer that. I know that in the public safety sector of society, everyone pays the price when it comes to fuel costs. Prescott, as an example with it's large senior citizen population, has created a fuel burden on local departments. Even though around 80% of EMS calls to 911 turn out to be non-emergent in nature (sometimes it is just an abuse of what 911 was designed for), we still burn lots of fuel to respond and transport in case that 911 call is truly an emergency. How does this affect everyone? Very simple, taxes have to go up to cover the cost of "responding". This will only continue, since our population is growing. This could be the same for other countries. For a society to change and help shave the use of oil (as an example), we have to promote alternate means of transportation. Prescott is still fighting over on putting more bike lanes in. This is only an example. The same can be said for food demand. Simple supply and demand will suggest that with a growing population comes a higher demand for the potentially limited food supply. This will only raise prices. These are very large issues that can't be ignored. It is sad that the world is just now trying to figure out what to do, but are we to late?

Unit 4, Lab 2

This is a human demographics lab that compares the different fertility rate against the the whole world population.

1. What was your high fertility rate country and what was its fertility rate? My high fertility rate country is Somalia, with a fertility rate of 7.11

2. What was your low fertility rate country and what was its fertility rate? I used the U.S. because the fertility rate is at 2 and this is our home country.

3.The high fertility rate in Somalia represents that many issues that face that country. There are many births that can contribute to the country and its lack of industrialization. Which i find interesting because it is a very poor nation with very little help in terms of food and medical supplies. This is proves to show that the average life span is low when compared to the U.S.. This has the potential to effect the world because we are already experiencing a large demand on resources due to the Asian population becoming more industrialized. This will only compound the issues at hand as more countries become even more dependant on our worlds limited resources.

4. In the low fertility rate country, the middle aged class has grown, in my opinion, because those societies have more to offer in regards to choices in living a more structured life because of the need to have income in order to keep up with the cost of life. People are becoming more focused on income in order to "have a life". You can have more money to live off of if you do not have children to support. So, in my opinion, people are having less children, which in turn, gives us a higher middle-aged class vs. the fertility rate.

5.Middle aged no children: Focused, driven, set in their ways, structured, professional, bad drivers, slow, rude, have to be catered to, taxing(abusive) on the U.S. health care system.

Children: Fast, funny, no-care, really enjoying life, no worries, reckless, bad drivers, limited regard to respect, loud, play full, not focused.

Final Lab

This final lab will list 20 species that i will interact with on any given day.

1.Fire Ant- Solenopisis invicta. Predation since they seek out food that is alive or dead.

2.Dog- Canis Lupos Familiarias. Mutualism because we both benefit but i have the overall advantage

3.Cat- Felis catus. Tricky because cats are predators, we both benefit with the attention given and received.

4.Hamster- sub family Cricetinae. Commensal, because my kids and the hamsters both benefit from one another.

5.earthworm- phylum annelida. Mutualism because the worm decomposes sediment.

6.horse-equus caballus- Mutualism for humans and horse because they provide labor uses and relaxation to humans.

7.house fly- musca domestica- Commensal because fly help to decompose organics, but they can make us ill.

8.quail-phasianidae or in the family odontophoridae- Symbiotic since they provide food and help keep insects in check.

9.rabbit- leporide, cotton tail genus sylvilagus- Symbiotic- mutually benefit as food source and helps with foolige.

10.plum- genus prunus, family rosaceae- Symbiotic since it is a food source and a source for pollination.

11.Russian sage- Perovskia atriplicifolia. Commensal since the bees use the pollination for many things in our eco-system.

12.rose plant- genus rosa, family Rosaceae. Same as the sage, Commensal

13.cheery tree- genus prunus, family rosaceae-Symbiotic due to food source and the pollen production.

14.grape vine- vitus, vitaceae. Predation, because its vines "choke" out any shrubs near it.

15. Spaghetti squash- cucurbitapepo, i find the interesting because out of the fruits and vegetables at my house, this is the only one that is an American native. Predation because of its aggresive vines.

16.tomato- solanum lycopersicum. Symbiotic because we benefit from the plant and it benefits from our "up-keep"

17.cattle- bovines. Parasitic, because they eat plants and then we eat them.

18.Corn/Maize- family poacea, genus Zea

19.wheat- family poaceae, sub-pooideae, genus triticum. Mutualsim since wheat grows and produce food we farm it then harvest it.

20.cricket- insecta, orthoptera, gryllidae. Parasitic to foliage but used as a food source in some countries.

1. How is a new organism started.

a)Mitosis- Somatic cell division that produces 2 daughter cells that contain the same number and kind of chromosomes as the original cell.

b)Meiosis- Begins with a diploid stem cell. After 2 divisions, 4 gametes are produced.

c)Fertilization- Union of a sperm and egg to form a zygote. This is the first cell created in order to create a person.

d)Pre-Embryonic- First week of embryonic fetal development

1) Embryonic Development- Begins 2nd week and lasts until the second month of development.

e)Fetal Development- Uterus is growing since the baby is being constructed. This will continue until birth of baby.

f)Eggs- Produced by the ovaries, lives 6-24 hrs unless fertilization occurs.

g)Sperm- Produced in testes, and transported by semen secreted by the prostate and seminal gland during ejaculation
