Discussion a solution to the problem of protecting endangered species - Essay Example Humans must realize that we are not the only creatures which use the world. Many species of animals are all around us, and sometimes our activities destroy the specialized habitats that these animals need in order to live, produce young, and have enough to eat. In the case of the right whales, conservationists recognized a need to preserve this rare and beautiful animal which was hunted nearly to extinction before being protected. Once protected, human activities were still killing the whales. The shippers did not have to entirely eliminate using the Bay as a port, but changing the routes to avoid the places where the whales spent their time meant that continued human activity would not continue to destroy the endangered species. This example shows that it is possible for conservationists, activists, industry and government to work together toward a common goal. Sometimes activists would like to completely prevent industry from exploiting natural resources, and sometimes industry does not make wise choices and completely destroys the habitats of endangered animals. The result of the small change in the Bay of Fundy was a record number of right whale births in 2009, which is a big step toward rebuilding the population of this endangered species. Small changes lead to big changes when humans pay attention to their

Discussing Issues Relating to Oceanography Assignment

Discussing Issues Relating to Oceanography - Assignment Example A substance melts when its molecules move apart and have a â€Å"wider range† of motion than is possible in the solid state (Yong and Wai 197). During boiling or conversion from liquid to vapor state, energy is not only required for overcoming the attractive forces between molecules but also for expanding the vapor against the atmospheric pressure. The energy required for this process is called latent heat of vaporization. In this case, too, the kinetic energy of the molecules remains constant. Latent heat of melting only breaks down a few bonds between molecules while latent heat of fusion breaks down all the bonds. Moreover, during vaporization, the molecules are reorganized more vigorously than during melting. Therefore, the latent heat of vaporization is greater than the latent heat of fusion. For example, the latent heat of melting of ice (6.0Ãâ€"103 Jmol-1) is only 15% of the latent heat of vaporization (Adkins 79). This is because of the strong intermolecular forces between water molecules. Water molecules are polar because of charge separation between the oxygen and hydrogen atoms, where oxygen atoms are partially negative and hydrogen atoms are partially positive. Because of the presence of positive and negative poles, each water molecule bonds with other water molecules. This leads to strong intermolecular hydrogen bonding. The boiling point and the freezing/melting point of water are higher than that of other compounds of similar makeup, such as H2S, H2Te and H2Se, because larger amounts of heat are required to overcome the strong hydrogen bonds in water compared to other compounds where hydrogen bonds are absent. Thus, the freezing point of water (which is equal to the melting point) is 100 ºC higher than expected and the boiling point is 200 ºC higher than expected (Spencer, Bodner, and Rickard 333).
