We should be trying to prevent species from becoming extinct.

The extinction of species is part of the nature, so there is no point for human to make efforts to protect endagered speicies. "-since the whole idea behind the natural process is to kill off the weak to allow the strong to survive." 'No species on earth would put the interest of another species above its own, so why should human beings be any different? Furthermore, since the very beginnings of life, Nature has operated by the Darwinian principle of "survival of the fittest". Life forms that cannot keep up with the newest species on the block will always risk extinction, unless they adapt to the new challenge. Man has no obligation to save the weaker species; if they cannot match our pace, they deserve to die out and be supplanted by others.' "Another important aspect of preserving endangered species is the importance they bare or may bare on scientific research, many times this research leads to the benefit of the well being of humans." Since you have chosen to show examples of species that are benefitting the well being of humans, I shall show examples of species that are hazardous to humans. 'How would you like to be sitting at the beach watching your kids play in the water when a wolf comes out of the brush and starts going after each of your kids. Helplessly, these kids fought for their lives as a lone wolf caused havoc biting six people on a rampage. This event happened up in Canada just last week. The wolf was later found and killed by wildlife officials.' (http://blog.kingsoutdoorworld.com...) 'The girl was playing Friday in a sandbox at Alterra Park in Chino Hills in San Bernardino County. Around 10:30 a.m., the caretaker heard screaming and saw a coyote trying to carry the child off in its mouth, officials said.'(http://www.foxnews.com...) 'Mosquitoes Malaria is transmitted by the bite of an infective female anopheline mosquito. It occurs mainly in the summer and especially during years of good rainfall. Anti-malaria tablets should be taken before going into a potential malaria zone. In areas where malaria has become chloroquine-resistant, alternative drugs should be used. Pregnant women should avoid malarial areas. Mosquitoes feed from dusk to the early hours of the morning. Camp on heights such as hills where a cool wind blows and where the grass is not very thick, away from standing water and not near densely vegetated areas at pans or rivers. Sleep under a mosquito net and use mosquito repellants. Fire and smoke help, and burning Elephant or cattle dung apparently drives mosquitoes away. The symptoms appear approximately 12 days after the infective bite. Early symptoms include fever, chills, sweating and headache. Prompt treatment is essential even in mild cases, since irreversible complications may appear suddenly. If the early symptoms are not recognised, the victim may become critically ill with cerebral malaria. Bilharzia When visiting areas where Bilharzia (Schistosomiasis) is found, contact with contaminated water should be avoided. Bilharzia is found in shallow water that is stagnant or flowing slowly, along the banks of rivers, dams and pools, and especially where plants are growing in the water. If you wet yourself with contaminated water, clean yourself immediately by rigorously rubbing yourself dry with a cloth. The parasite may penetrate the skin within minutes. Contaminated water should be boiled or purified before being used for drinking or washing. Bilharzia infection can be severely debilitating and unpleasant and is not easily cured. In rare cases it can go to the brain, with lethal results. As the skin is penetrated, the first symptoms may be a skin reaction, although this may be mild or may not even show. Other symptoms include persistent fatigue, bodily discomfort, fever and vague intestinal complaints. If in doubt, a doctor should be consulted. Tsetse-fly The tsetse-fly, which transmits sleeping-sickness, has been virtually eliminated in southern Africa and only small populations exist. The fly can inflict a painful bite, and the symptoms of the disease, which include headache and a fever, develop after about two weeks. Bees and wasps With repeated exposure to stings, some people become hypersensitive, after which another sting could be much worse, if not fatal. People allergic to bee and wasp venoms should not wear floral-scented cosmetics or nail varnish. The solvent (amyl acetate) in nail varnish is the alarm pheromone of bees and provokes aggression. Don't wear brightly patterned clothes. If bees are about, remain calm and move slowly. Ticks The symptoms of Crimean-Congo haemorrhagic fever include a sudden onset with fever, malaise, weakness, irritability, headache, severe pain in limbs and loins, and marked anorexia. Vomiting, abdominal pain, and diarrhoea occurs occasionally. Soft ticks If bitten, hypersensitised individuals risk anaphylactic shock, which can result in death. And , spiders.'

Also, "-Finally, an example of species providing for scientific discoveries is the instance of the Pacific yew which "became the source of taxol, one of the most potent anticancer compounds ever discovered" (Wilcove & Master, 2008, p. 418-419)." Modern science has advanced to the point where inspiration from Nature is no longer required. Today, medicines derived from natural products are in the minority. In any case, the upcoming era of genetic engineering will allow mankind to rid himself of disease without resorting to medicines.
