Crop Production - 879 words
Beginning about 12,000 years ago, the human population began a trend that completely changed the way we, as a race, evolved. For the first time in history, humans pushed beyond the restraints of traditional hunting and gathering, into domestication and farming. It was a change that would not only take thousands of years to prove worthy, but also may have set us back on the evolutionary path at the time. Along the path to this point, we have been constantly changing and finding new ways to produce and maximize the yield of the crops we sow. Have these changes been successful or detrimental to us? The following will search into answering this question. Since the beginning, increased crop produ ...

... d warming of climate where there is an increase in the growth of plant material and plant foods. This change would have promoted a growth in subsistence farming, at the very least. This would have increased the amount of plant carbohydrates and thus there was an increase in the occurrence in evidence of caries. Again in the Mesolithic there is further warming in the surrounding climate to the point where an even greater amount of plant food harvest is attainable for human consumption. Frayer found that for the Mesolithic, there was a negative correlation between rates of caries and latitude. This was the case where skeletal assemblages from northern sites continually show a decrease in c ...

Reasons To Kill Animals - 828 words
As a woman and animal lover, I could understand Joy William's feelings and motives in The Killing Game. Ms. William's believe that hunting or killing of animals is "murder, murder, murder". In this essay she states point blank that she is completely against hunting of any kind and for any reason. I can sympathize with her love and appreciation of animals, as I am a true animal lover and enthusiast. I am also, however, a rancher who Ms. William's ridiculed in her essay. I firmly believe in hunting over-populated game and predators of our livestock. I feel that hunting is a necessary act to keep a balance in our ecosystem between the people and animals of our world. Ms. Williams makes many tru ...

Aldo Leopold Ecocentrism - 791 words
Ecocentrism: The Land Ethic By: Aldo Leopold This is a summary of Leopold's ideas and my views on them. 1) Leopold strongly suggests the need for land ethic because he sees a great lack for it. Humans see land as an economical resource. Land is used for our needs and enjoyment with the belief that we are the ruler and conqueror of the land. Humans feel superior to the land and all that live on it and therefore lack the sense of being a part of land. To have land ethic is to become a part of the land not a disconnected from it. When we separate ourselves from the land, we forget our obligation to take care of it. We use, abuse, and take land for granted. We are the ultimate consumers of land. ...

History Of Aids - 1,418 words
Debate around the origin of AIDS has sparked considerable interest and controversy since the beginning of the epidemic. However, in trying to identify where AIDS originated, there is a danger that people may try and use the debate to attribute blame for the disease to particular groups of individuals or certain lifestyles. The first cases of AIDS occurred in the USA in 1981, but they provide little information about the source of the disease. There is now clear evidence that the disease AIDS is caused by the virus HIV. So to find the source of AIDS we need to look for the origin of HIV. The issue of the origin of HIV could go beyond one of purely academic interest, as an understanding of whe ...

Meteor Impacts - 579 words
Meteors are very common throughout outer space. They are being whipped around our solar system in every orbit possible. Normally they are peacefully and serenely floating through space, but one just has to look at the cratered face of our moon or Jupiters moon Callisto to see that more than a few meteors journeys through space have been interrupted. The earth has been hit before and will be hit in the future, statistics show this. We must detect the meteors a long time before they cross paths with Earth to prevent an impact. The likelihood of a significant meteor impact in the near future is extremely small, but it is still a possibility. The earth is just like every other planetary body in ...

Desert Tortoises - 1,127 words
Vulnerable to the harsh desert conditions, the desert tortoise spends almost all of its time waiting out extreme temperatures in its underground burrow. There, this armored, terrestrial turtle conserves its energy and stays relatively cool during summer months, and relatively warm during winter months. This turtle, Californias official state reptile, carries a high-domed tan to dark brown carapace (shell), which protects them from most predators. Yet even those shells are unable to shield the desert tortoise from such threats as the golden eagle and the automobile. Desert tortoises commonly dig their burrows in dry, gravelly soil beneath creosote bushes, large shrubs, or beside washes in the ...

The Impact Of A Car - 1,192 words
... ectric car came out a couple of years ago, which people thought would be a great idea. Electric pumps at every gas station, a charger at your house, good idea, right? No, wrong. Two main sources of pollution during the ownership of the electric car (not including its manufacture) are the source of electricity itself, and the production and disposal of the lead and sulphuric acid of the batteries. Two other bad points about the electric vehicle include the fact of how unattractive they are and how hard it is to change them up all the time, and the power doesnt last very long. In my opinion, the best alternative is the Nissan Sentra Clean-Air Model which is compared to the Sentra GXE. The ...

Global Warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earth's surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that have started and will continue to occur in the coming decades. Life could not exist if there was no natural greenhouse effect. The reason for the natural greenhouse effect is so that all the creatures living on Earth can live and breathe.
