The development of genetically modified (GM) plants and animals had led to a huge global controversy. Opponents say that GM “Franken foods” are a threat to our well-being, and proponents say that the risks are minimal. There is one aspect of the war over GM that is often overlooked. Anyone who wears a cotton shirt these days is using a GM crop. Cotton is the only major non-food GM crop at present, but others are coming.

GM cotton plants that is not food has not stopped the most passionate GM opponents from objecting. If GM cotton is grown in a field next to fields of non-GM cotton, they argue, then how to keep genes from being transferred from field to field. This danger, however, is not as compelling to the public as possible health hazards in food, so there is no great fury over GM cotton.

GM cotton seeds produce higher yields, and they do without the need for pesticides. Planting of GM cotton has increased five fold since 1997; three-quarter of cotton in America, and over half in China, is now GM. Farmers like it because it increases their profits.

Other options for non-food GM include new variety of flowers with different colors or scents, tougher grasses for lawns, and plants designed to soak up pollutants from the soil. The paper industry provides another example of potential for GM to help produce better and cheaper products. Paper is made from pulp, and pulp is generally made from trees. Researchers in New Zealand and Chile have been working on insect-resistant pines, and a Japanese firm has combined carrot genes with tree genes to make them grow better in poor soil.

Another interesting case is that of tobacco. It is not food crop, but it is consumed, and GM tobacco plants with both more and less nicotine have been created. The tobacco plant, however, is an ideal target for GM, since its genetics are very well understood and it produces a lot of leaves. The value of the drugs that could be produced by GM tobacco is so high, many farmers could switch from growing tobacco for cigarettes to growing it for medicine. Since medical cost is rising, consumers would also be happy to use drugs produced in bulk by GM tobacco.

If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salt behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea, off Antarctica, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

Which of the following is NOT a result of the formation of ocean ice?
