... trees is cleared by either being logged or burnt. Two other deadly greenhouse gasses which are entering the atmosphere even faster than carbon dioxide are methane and chloroflourocarbons, although they are not as damaging in the long run. These increases are likely to affect worldwide temperatures dramatically. In 100 years time the average temperature for most parts of the world will increase from between 2C to 6C if greenhouse pollution continues at its present rate. This temperature increase would drastically affect the growth of many different crops and cause the polar ice caps to melt, thus increasing sea levels to rise up to several metres. I ...

... is probably because they have to carry a whole other organism within (Harman, 1996, 21). Basking sharks have, at some point in time, also been known as the elephant shark, the Bone shark, sailfish shark, and sunfish. The reason this shark is occasionally referred to as the Bone shark, is because when they die, they sink (their density is greater then the water's density) and are ravaged among the sea floor, by rocks, etc. (Steel, 1985, 132). However, when they do finally wash up on shore they are usually quite mutilated; their skeletons are all that remain. Hence the name, Bone shark. Although the Basking shark most ap ...

... by more than 40 per cent from 1980 to 1993. In the same period, Norway's emissions were reduced by more than 70 per cent. · As a result of higher precipitation in recent years, sulphur deposition has not dropped as much as might be expected from the reductions in emissions. · Estimates of how much pollution the environment can absorb without damage are called critical loads. · Sulphur, like nitrogen, is essential to all animals and plants. The natural sulphur cycle includes volcanic emissions, sulphate in sea salts, and sulphur compounds produced by marine organisms. On a global basis, emissions from such sources are of about the same order of magnitu ...

... are used in making plastics and in aerosol spray cans, refrigerants, air conditioners, and similar objects. Like carbon dioxide, the CFCs are trapping more heat in the earth's atmosphere. CFCs have also been blamed for ozone depletion. CFCs are suspected of breaking down ozone particles that shield us from the sun's ultraviolet rays. Too many ultraviolet rays can cause cataracts and skin cancer. A hole in the ozone has been discovered over Antarctic the size of the United States. The hole is actually where the ozone has been depleted or thinned by the CFCs. The use of aerosol cans accounts for most of the release of CFCs. This resulted i ...

... spending on other things such as fixing highways, better healthcare, and more funding to school. Nuclear power is also a lot environment wise. Nuclear power requires a mere fraction of the space that is required to set up a solar, wind, or hydroelectric generating station which. This will allow more space for private landowners and will also keep land prices at a lower cost. Nuclear power is also a much cleaner operating type of fuel. The amount of waste produced is from a nuclear power plant is not even a fraction of the amount of sulfur, carbon monoxide, and nitrogen oxide produced by a coal plant. By building a nuclear power we will reduce acid rain and not a ...

The jaguar is predominantly a forest dweller with the highest population densities centring on the lowland rain forests of the Amazon Basin - dry woodland and grassland also serve as suitable terrain, although the cat is rarely found in areas above 8000 feet. The overall body size and coloration of the cat often relates to its location - found in dense forested areas of the Amazon Basin are often only half the size of those found in more open terrain and it has been suggested that ...

Some traits are not politically and religiously charged: the hardness of the enamel on your teeth, which is controlled by a single gene, whose location is known, and who’s function we do understand. Now scientists are attempting to find proof if the infamous “gay gene”. For years, the gay community has been trying to prove that they were “born gay” and that their lifestyle was not choice. The news media has a ridiculous double standard for the trait "sexual orientation" and every other trait. ABC's science journalist David Marash reported on Nightline that a gay ge ...

Diagnosis can be difficult because many of the critical diagnostic features change with age. It is most difficult to diagnose in newborns and adults. Reaching an FAE diagnosis is even more difficult because only some of the symptoms are present, and possibly not as visible. This disorder cannot be detected by genetic testing because the damage is done after the baby is born. It is not known how much a pregnant wom ...

... have more traction in the higher elevations. The kangaroos that live in the coastal regions also have several special adaptations. They have wider feet to allow them to walk is shallow water. They can eat several different types of sea plants. They can do this because they have a higher tolerance to salt than normal kangaroos. Kangaroos that live in forests have adapted to this climate as well. Their feet are wide to allow them to climb trees. This allows them to eat leaves off of the trees. They also do not have claws as long as other species. There is usually a larger supply of fresh water in the forests. FAMILY STRUCTURE A group of kangaroos livi ...
