 	"Americans should be aware that there is still a problem with elephant poaching and loss to the illegal ivory trade," Ginette Hemley, Fund's vice president for species conservation, told The Washington Post in September. And so our message is, 'Don't buy it, and don't take that chance'."

Even tiger's whiskers are sold because some people in Asia think they are a good-luck charm - like a rabbit's foot in the United States. "Part of our job is education," said Professor Dillon.

	Since the world became industrialized, the number of animal species that have either become extinct or have neared extinction has increased. Bengal tigers, for instance, which 'once roamed the jungles in vast numbers, now number only about 2,300. By the year 2025, it is estimated that they will become extinct.
What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not always interested in material gain but in personal gratification. This is an example of the callousness that is contributing to the problem of extinction. Animals such as the Bengal tiger, as well as other endangered species, are valuable parts of the world's ecosystem. International laws protecting these animals must be enacted to ensure their survival - and the survival of our planet. 
	Countries around the world have begun to deal with the problem in various ways. Some cou
