.... cutting, and an increase in population contribute to this problem. An example of this is the gold mining operation that we saw in the video. While mining, Mercury was dripping into the water. The mercury then got into the fish and into the humans who ate the fish. Biodiversity promotes a healthy environment. Environments rich in biodiversity are stronger and can with stand things such as drought, disease, and other stresses that environments that lack it cannot. In the video, during the drought, the side of the field with a more diverse environment held stern as the othe .....

.... seem to be obsessed with numbers and not trends. Let me illustrate this with tigers. There are frequently requests as to the exact number of tigers, or a tiger subspecies left in the world. That tells you that there are people that care. But there are so little tigers left that we can not even keep track of them. We should look at the trend that the population is taking, rather than the number as a slice in time. Just as you might say of a young member of the Hunt family, that they were very wealthy. A hypothetical individual was 24 years old and had $1,000,000. What isn't .....

.... 1). Possible problems may include: difficulty in falling asleep, waking up in the middle of the night with difficulty returning to sleep, waking up too early in the morning, brief periods of REM sleep, unusually long periods of stage 1 (light) sleep, or unusually brief periods of stage 3 and 4 ( deep, restorative) sleep (depression.com 1). Weight and depression are also commonly associated with each other. Many people begin loosing interest in eating which results in weight loss. Others may experience the opposite effect and gain weight .....

.... (adenosine tryphosphate) that is used for energy, made by the kidneys, which can cause the kidneys to stop producing ATP because of an overload of ATP being made from the Creatine. This can result in kidney or liver failure. Constriction of the blood vessels occurs when you use Creatine and work out for extended amounts of time. This can cause major constriction of the vessels around the heart causing abnormal heart rates and heart attacks. Pancretitis is another side effect where the pancreas stops working and fails. Creatine is said to be directly related to pancretitis if i .....

.... in danger. We can help these animals and plants by making laws that you are not allowed to hunt or kill any animal that is in danger of extinction. Government Involvement Only since the 19th century has there been worldwide concern about the case of species in their natural environments. Finally in 1916 they made a law called Migratory Bird Treaty. They had this law in United States, Great Britain, Canada, and later in Mexico. This law was made so that people can not kill animals that are endangered. This law did not work that well because the animals that were endangered .....

.... how earthquakes are formed and occur, how scientists can more accurately predict the arrival of earthquakes. Before contemplating how earthquakes might possibly be prevented, it is essential that the process and formation of and earthquake be understood. Earthquakes are caused when the earth's crustal plates move, rub, or push against each other. The earth's crust (the outer layer of the earth) is made up of seven major plates and approximately thirteen smaller ones. The name plate is used to describe these portions of the earth's crust because they are literally “plates” o .....

.... agitation. An example of a runaway greenhouse effect is Earth's near-twin planetary neighbor Venus. Because of Venus's thick CO2 atmosphere, the planet's cloud-covered surface is hot enough to melt lead. Water vapor is an important "greenhouse" gas. It is a major reason why humid regions experience less cooling at night than do dry regions. However, variations in the atmosphere's CO2 content are what have played a major role in past climatic changes. In recent decades there has been a global increase in atmospheric CO2, largely as a result of the burning of fossil f .....

.... we do not have the technology to mine it at a cheap cost. Chapter 2 Mining When uranium is extracted, pitchblende is broken up and mixed with sulfuric and nitric acids. It then dissolves into uranyl sulfate. With the addition of sodium hydroxide, uranium is precipitated as sodium diuranate which is known as the yellow oxide of uranium. To get uranium from carnotite, the ore must be finely ground and treated with a hot solution of caustic and potash to dissolve out the uranium, radium, and vanadium. And after the sandy matrix is washed away, the solution is treated with sul .....
