ETHICAL ISSUE FOR UNIT IV

Who should reproduce? These guys.....

After this Unit I still fill incomplete about the population effect on the plant and our countries. I still am of the feeling that the biggest issues in our future are based around three things. Those factors are population, food sources, and disease. This is what I have come to believe.
The fact that our population on this planet is reaching the billions it is, many problems are going to come from it. When you have growth at exponential rates all planetary life is affected. The resources it takes to sustain these numbers the planet can’t afford to produce any more. With the trend in a greener more efficient life style in place we should start looking way ahead to secure supplies for us that don’t kill our big home, planet earth.
To feed the numbers of this planet you have to do some major figuring just to get an idea. The top producing countries still feed all of the poor ones. Yet the poor one has the high birth rates and is continuing to grow. What should we do cut them off in an in human way and let them fend for there selves. No, but it might come down to that in the future. Food is going to be a big issue, when do we just take care of our own.
With the huge populations there has to be some kind of bug that is going to come along and get us. The cultures are designed perfect for passing it on to one and other. Just think of how many people you come in contact with. Not only is that but the world still very small with all of the international travel. We have no way of controlling it. Maybe that is Mother Natures plan for species control. If it gets out of hand, boom there a disease and most of you’re going to die.
This unit was fun and interesting because it made you thinks of how we live and interact with the e environment we live in. Also what we do to affect it. I think that the population is going to get too big for the planet and food will either run out or a disease will come along and kill off most of the populations. Will see; hope it not in our life time.

Evolutionary history-
The concept of time, a lot of time some 4 billion years
Over that deep time molecule formed and started creating life at cellular level

Evolutionary evidence-
Fossil record
Anatomical similarities
Common embryological features
Common Shared biochemical and genetic features

Humans and Primates-
Human’s closest relatives are monkeys and apes
We share a common deep time ancestral with all species
The fossil record shows many different human and human-like species living at one time
Homo sapiens evidence
Ability to interbreed
Little anatomical difference among populations
Little biochemical difference among populations
DNA and protein analysis show recent single common ancestor

Natural selection
Evolutions Reality Show-
The most adaptable and strongest past on genetics to off spring
Environments and culture play major roles in evolution
Humans dominate planet altering evolution by artificial selection

Ecology
Physical landscape
Water Cycle-
Water transfer rate between ecosystem components
Carbon Cycle-
Exchange rate of Carbon Dioxide in atmosphere to ecosystems
Nitrogen Cycle-
Conversion of Nitrogen gas to ammonium
Phosphorus Cycle-
Ocean sediments containing Phosphorus moving to land masses

Biological landscape

Biodiversity-
Variety of life on earth, described in terms of the number of different species.
Types-
Symbiotic: mutually beneficial, both species benefit
Parasitic: one species benefits (“parasite”) and the other is harmed (“host”)
Commensal: One species benefits, the other is unharmed
Mutualism: both species benefit, like symbiosis, but it may appear one species has the advantage, but evolutionarily, over the long-term, both benefit
Predation: Usually considered parasitic, where the predator is the parasite, but can also be seen as mutualistic
A sustainable society would not become Parasitic as we have become in recent years

Alien species-
Exotics are non native members of an ecosystem.
A sustainable society would control these species movement

Pollution-
Environmental change that adversely affects the lives and health of living things.
A sustainable society would use recycling and composting, multi use agriculture

Medicinal value-
Medicine that has originally derived from living organisms.
A sustainable society would use organisms for the better of the planet

Agricultural value-
Wild plants that have been modified to become high producers.
A sustainable society would lower artificial productions

Human Population Demographics Online Lab

1. What was your high fertility rate country and what was its fertility rate?
Somalia, with a fertility rate of 7.11
2. What was your low fertility rate country and what was its fertility rate?
Canada, with a fertility rate of 1.73. The initial demographic "shape" of your high fertility rate country should have been a pyramid, with high population in young age groups. Explain why high fertility rate results in a high percentage of young people in the population. How does this affect future population growth?

The reasons for high fertility rates in this country derive from the poor economy. During tough times or in area of lower standards of life the population tends to increase. The possible reasons for that is people have nothing better to do then to just have children, it a fun past time. The lack of resources has no determinant on these life styles. The ultimate effect is there will be an exponential increase in population and the starvation and disease will kill of the weak or poor.4. Your low fertility rate country might have had a more oval-shaped curve with high population in middle age groups. This is especially exaggerated if the fertility rate is below 2.00. Explain why low fertility rate leads to lots of middle-aged people.

The possible reasons for this lower fertility rates have to cultural pressure. The Ideas of not being able to provide for you off spring and the strong family values puts the breeding in control. Also the drive to enjoy other fun entertaining parts about life has held back the growth in population.
5. Write ten adjectives or descriptive phrases for what you might expect life, people's attitudes, conditions on the streets, etc. will be like in each of those situations. Imagine a situation with lots of middle-aged and older people in the population and write ten quick "brain-storm" descriptors for you think it would be like (Prescott, Arizona?). Then do the same for a situation with lots of children in the population.

High fertilization rates-
Lazy, non driven, scared people that have no education, strong instincts to the desire of intercourse, nothing to look for in values because they have had no parenting growing up.
Low fertilization rates-
Motivated, educated people that like to enjoy their past times, have been raised to be considerate to the culture they live in and the planet. They have jobs and are focused more on them selves.
Older Group-

Slow to change if at all, set in their ways, no visions for the future never had to think about it, well mannered, good ethics and morals.
Younger Group-
Just don’t care about much, lazy and un motivated, no work ethics, no common sense, but sure can play with technology and focus on how to get away with not doing much.
