Frequently, several forms of environmental change are responsible for the disappearance of species. For example, as tropical forests are cut down, primates have progressively smaller feeding and living spaces. They also become more accessible to ... used to feed animals that are raised for their pelts, such as sable and mink. Thus, the wearer of a ranch-raised Russian sable coat may have indirectly contributed to the ultimate disappearance of the great whales.

In the final section of the poem Substance, Shadow, and Spirit he discusses the Taoist view, which is that one should not ...
- 4453: Cloning
- ... the interests of humanity as a whole. This includes providing funding for, and endorsing cloning research. The ban on human cloning should be reconsidered. The positive aspects that cloning has to offer are entirely to great to ignore. Recently the United Nations has adopted a declaration against cloning. The declaration calls on all nations around the globe to ban reproductive cloning (HCF 1999 ). There are more reasons to clone human beings ... plants. Imagine all of the species of life on this planet that may never have become extinct if were able to clone. Never again would we be forced to stand by idly, watching as a great animal becomes little more than a fossil. Cloning would allow us to make extended journeys into our universe. By perpetuating our physical selves scientifically, we could embark on space journeys of infinite distances. We would ...
- 4454: CLONING HAS SCIENCE GONE TOO F
- ... provide them with the natural habitat that they need. Let us not forget that it is the diminishing environment from which they come that is to blame for their extinction. And while it would be great to save the Panda bear population, we should focus our efforts more towards the real reason for their extinction. As stated earlier, there are many possible genetic deficiencies that can result from cloning. Now, taking ... produced in a natural environment. Undoutedly, the most beneficial result that cloning can present is the ability to create organs. But, we must realize the risk involved as well. There would most likely be a great many failures before there were to be even one success. And there is no substantial evidence that this would even be possible. So the risk seems to greatly outweigh any possible benefit. The risks involved ...

- ... at the start of the regimen); spotting (light bleeding at times); change in menstrual flow (most commonly lighter flow than one is used to); breast changes such as increased tenderness, enlargement, secretion; change in weight, depression, intolerance to contact lenses. Women who suffer from migraine headaches may experience an increase in migraine occurance. It is important to always, always mention to any doctor you are visiting the type of birth control ... related to progesterone or estrogen. This is important, because while for most people estrogen related side effects, such as nausea, will usually diminish or stop within a few months, progesterone related side effects such as depression and diminished sex drive tend to only get worse over time. These side effects can usually be remedied by simply changin formulas, though. No serious side effects of overdosage have been so far reported. Most ...
- 4456: BLACK HOLES
- ... a black hole is, we must first take a look at the basis for the cause of a black hole. All black holes are formed from the gravitational collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then ...
- 4457: Genome Sequencing
- ... relatives, evidenced by the observation of many similarities between the two groups. For example, in all information processing systems, that is, translation, transcription and DNA replication, the archaeal and eucaryotic versions resemble each other a great deal more than either genome resembles the bacterial version . Other resemblances between Archaea and eucaryotes include histones, cell division proteins, proteosomes, and protein transport systems. Despite these similarities, the archaea resemble the bacteria in morphology ... a weak, and in a sense immature, discipline, and as such, molecular data is being used readily to develop a new phylogenetic system . Because the universal phylogenetic tree brings us face to face with the great evolutionary questions, our growing ability to formulate these in molecular and genetic terms is particularly exciting. We can now inquire about the origins of not only the eucaryotic cell, but also parts of the eucaryotic ...
- 4458: Global Warning
- ... next 20 years and save money; but another claims that a reduction of twenty percent below 1990 levels would cause a drop in the U.S. Gross Domestic Product by 1 to 2 percent".

- 4459: Gold And Its Uses
- Gold's great virtues of malleability, ductility, reflectivity, resistance to corrosion and unparalleled ability as a thermal and electrical conductor mean it is used in a wide variety of industrial applications consuming close to 300 tonnes annually. Gold ... over 30 open-pit operations, of which the largest is Gold strike with an expected average production of over 50 tonnes per year. Historically, Russia was one of the earliest sources of gold.

- ... necessarily indicate an extreme health hazard. For example, roasted coffee contains 800 volatile chemicals, of which only 21 have been tested on rodents, and of those, 16 were carcinogenic. Coffee has never been considered a great cancer-causing substance, though. Cannabis has also been known for its many therapeutic uses, including the treatment of open angle glaucoma, asthma, and the nausea associated with chemotherapy. It has also been described as a ... physical effects, yet are as accurate today as they were 100 years ago. Following is an early account of its intoxicating properties made by Dr. John Bell in 1857: "I had taken the drug with great skepticism as to its reputed action, or at any rate with the opinion that it was grossly exaggerated, and I accordingly made up my mind not to be 'caught napping' in this way again, and ...
