Seeing the World Centuries Ago
If you enjoy looking through travel books by such familiar authors as Arthur Frommer or Eugene Fodor,it will not surprise you to learn that travel writing has a long and venerable history.Almost from the earliest annals of recorded time individuals have found ready audi-ences for their accounts of journeys to strange and exotic locales.
One of the earliest travel writers,a Greek geographer and historian named Strabo,lived around the time of Christ.Though Strabo is known to have traveled from east of the Black Sea west to Italy and as far south as Ethiopia,he also used details gleaned from other writers to extend and enliven his accounts.His multivolumed work Geography provides the only sur-viving account of the cities,peoples,customs,and geographical peculiarities of the whole known world of his time.
Two other classic travel writers,the Italian Marco Polo and the Moroccan Ibn Battutah, lived in roughly the same time period.Marco Polo traveled to China with his father and uncle in about A.D.1275 and remained there 16 or 17 years,visiting several other countries during his travels.When Marco returned to Italy he dictated his memoirs,including stories he had heard from others,to a scribe,with the resulting book Ⅱ milione being an instant success.Though difficult to attest to the accuracy of all he says,Marco's book impelled Europeans to begin their great voyages of exploration.
Ibn Battutah's interest in travel began on his required Muslim journey to Mecca in 1325, and during his lifetime he journeyed through all the countries where Islam held sway.His travel book the Rihlah is a personalized account of desert journeys,court intrigues,and even the effect of the Back Death in the various lands he visited.In almost 30 years of traveling it is estimated that Ibn Battutah covered more than 75,000 miles.

Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.
Eleven gray whales have died in the San Francisco Bay in the last three weeks．No one knows why the whales are dying.
Last year 270 whales died along the whales'migration route．Many people think starvation is the cause．This year the dead whales seem to have more blubber(fat)on them.
Twenty years ago,the gray whale was listed as an endangered species.
Some scientists think that the larger number of whales makes it hard to find enough food．More whales create more pressure on the food supply,a supply that some scientists say may have dwindled as a result of the warm waters of El Nino.
Most of the whales have been dead for many days before they are found and studied．This makes it hard to find the reason for death.
65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year．The whales could be dying from many diseases,but it may be over-population．
