.... is the one to take over. The females are usually responsible for the nursing portion in the unit. Gorillas are peaceful and tolerant by nature. Whenever two groups meet, they either ignore each other, or they give each other a grumpy grunt. Sometimes the two groups would even stay together, and then eventually separate. There are many rumors about gorillas being very violent, but there are no reports about it. There are times when they have little mock fights, but there is never any blood shed in them. Right now there are not too many you will find in the Virungas. Their population is only in the hundreds. In 1960, there w .....

.... % of the ground temperature 70 % of the Earth is water so the readings would still not be acceptable. Orbiting satellites cover 99 % of the Earth's surface. According to surface-based temperatures, 1997 was the warmest year on record. According to U.S. government satellites and weather balloons1997 as the seventh coolest year since satellite measurements began in 1978. Further more, satellite and balloon based information, which uses different technology, concur with each other's readings according to NASA. My opinion is that surface-based information can not be relied on until it covers more land. Also, I find it difficult to argue wit .....

.... plants has been used for thousands of years for medical use only until the 19th century when use of cannabis spread from China and the Middle East to the population of Europe and America. Since that time cannabis became illegal and very popular drug known in all countries. In some way the affects of the marijuana may be serious. When smoked, the effects of cannabis begin immediately. When eaten the effects can take 1 to 2 hours to begin, depending on how much food is in the stomach. The effect after smoking cannabis may last for 1-2 hours and when eaten, the effects may sometimes last longer than 4 hours. One of the primary effects .....

.... not affected and the gene is recessive, she is now classified as a carrier. In some cases, there is no previous record of hemophilia in the family. Male children who would be born with hemophilia would be the result of the mutation of the gene. There are two types of hemophilia: Hemophilia A and Hemophilia B. Hemophilia A, also known as "Classical Hemophilia" is caused by a factor Vlll deficiency. This is the most common form of hemophilia. The second type of hemophilia, is Hemophilia B, and is sometimes referred to as the "Christmas Disease." Hemophilia B is caused by a factor lX deficiency. Both types of hemophilia are characterized .....

.... in humans or have been contradicted by other work. This section will address each of these reported negative side-effects. Various studies have claimed that cannabis destroys brain cells. However, several other studies found no structural or neurochemical atrophy in the brain at all. Furthermore, it should be noted that Heath's work was sharply criticized for avoiding safeguards of bias and reporting "changes" that occur normally in the mammalian brain. Wu et al. found a correlation between cannabis use and low sperm counts in human males. This is misleading because a decrease in sperm count has not been shown to have a negative eff .....

.... issues that are considered when loggers enter and area. Haphazard clear cutting of forests, while it maybe what Meadows would like us to think, does not happen. With every industry, every aspect is carefully debated and analyzed for the short and long term outcomes. Any industry that capitalizes on earth's resources figuratively signs a pact with the earth. This pact bonds this industry to the earth and requires that any harvesting of resources is not done so with haste and waste. There is a symbiotic relationship between the two. For the industry to exist there must be a constant supply of the resource. Without a constant supply t .....

Native plants "without assistance from a gardener in the area where they originated. Although all native plants are wild, not all wildflowers are natives" (Loewer 6). Where did the non-native flowers come from and how did they get here? "Probably the largest number of plants accidentally introduced in this country arrived in ships' ballast. Because the early merchant ships that sailed from Europe were empty of goods on the trip over, their hulls were loaded with dirt so that they would float pr .....

" A lot of concern has come from one certain crop and that is maize, which was altered to an extent. The development was done by a company known to be Swiss, called "Ciba-Geiby". That which was debated dealt with the Advisory Committee on Novel Foods and Processes (ACNFP) stating that "A gene resistant to the antibiotic ampicillin used in an early stage of the developmental process, could theoretically be passed to man via bacteria lodged in the gut of animals which eat the maize unprocessed (559)". .....

.... Since the 1600's, however, the rate of extinction has accelerated rapidly because of human population growth and resource consumption (17). Today, most of the world's habitats are changing faster than most species can adapt to such changes through evolution, or natural selection. The current global extinction rate is estimated at about 20,000 species per year, exponentially greater than the background extinction rate (17). Many biologists believe that we are in the middle of the greatest mass extinction episode since the disappearance of the dinosaurs 65 million years ago (18). The survival of ecosystems (plant and animal communitie .....

.... the reader know the credentials of the cancer researchers. Another example of poor credentials is when Viscusi states some percentages in "a 1991 survey of company smoking policies". He again fails to let the reader know the credentials of the survey. Another explanation as to why Viscusi's article is not successful is because the organization is confusing. The thesis Viscusi is trying to prove is that the are exaggerated. He fails to support his thesis because his main points in his story are all scattered and have no organization. Also, Viscusi's main point is that risks are exaggerated, but he fails to bring out the "risks" until after .....
