There’s very little more to tell. I picked up my thermos and the wrapping for the sandwiches, and started walking back. I was about half way back when I heard two shots, followed by a dull slam a few seconds later. Those two shoots usually mean a kill. I had forgotten there were other hunters that day.
Those hunters would never know they could have scratched his head…
10. Jane Goodall
In 1960, the twenty-six-year-old scientist Jane Goodall risked entering the thick bush. She intended to discover how chimpanzees(黑猩猩，缩写为chimp) were like human beings. She found out, instead, how much we are like them. Goodall broke new ground with her active involvement with some chimpanzees. She lived among them, ate and played with them and earned their trust by simply observing how they lived. Before Goodall, most visitors had frightened the chimps back into their rain forests. As a result, very little was actually known about them. Goodall, who insisted on going into the bush alone for longer periods of time, collected more information about apes(类人猿) than all other scientists put together.
Born in London to a writer and an engineer with a passion for car racing, Goodall received their daring and imagination---qualities that, along with her curiosity, would serve her well in her future occupation. She was inspired at seven by the stories of Dr Dolittle, the scientist who could talk to animals. And with her stuffed toy chimpanzee by her side, the young girl spent hours studying worms(蠕虫，蚯蚓) in the garden, hens in the henhouse, and whatever insects she could find.
After she graduated from high school in 1952, Goodall worked as a secretary at Oxford University. Even then she knew she wanted to go to Africa.
In 1957 she was invited to Kenya(肯尼亚) to visit a friend, where she met the world-renowned anthropologist(人类学家) Louis S.B. Leakey. Goodall’s enthusiasm impressed him and he hired her as an assistant. Leakey later recommended her to a two-year research project studying chimpanzees in Gombe(冈贝，位于坦桑尼亚).
It was a difficult decision to send a young woman, with neither a college degree nor scientific training, on such a demanding task. Leakey had trust in her, but his colleagues predicted the young woman would fail. Goodall proved them wrong. Goodall tried hard to observe the chimpanzees and to be observed in return. Eventually, the chimps grew to regard “this white-skinned ape” as their friend. Goodall made a number of surprising discoveries.
She found that chimps used tools to dig ants out of their hills for food. Goodall found that chimps experience a wide range of emotions like anger and grief as humans do. Her discovery was a significant breakthrough. Among her famous works are: My Friends: the Wild Chimpanzees (1967), and In the Shadow of Man (1971). These, along with her numerous films, TV specials and articles, made her one of the best-known scientists of the 20th century.
11. Oceans under threat
People use oceans for trade, travel, tourism, and recreation. We also take food and resources from oceans. All these activities can have harmful effects on the oceans and the creatures that live in them. Overfishing and pollution are the most common problems. Oceans link countries all over the world; seawater circulates around the globe, so what we do in one part of the ocean can affect another.
OVERFISHING In parts of the world, fishing boats with huge nets sometimes take too many of the same species of fish from a small area, causing some ocean waters to be overfished. As a result, there are not enough fish left to breed in these areas. This affects other fish in the food chain, and it affects people because there eventually may not be enough fish left to eat. In some parts of the world, limits have been set for the number of fish to be caught at one time.
THREATS TO MARINE LIFE Some species of marine creatures are now rare because too many have been killed for food or sport. Tropical islands and coasts with coral reefs(珊瑚礁) also attract large numbers of tourists every year. Indeed, this helps people develop an understanding of marine life. however, coral and shellfish(水生贝壳类动物) can be destroyed by heavy boats. Divers, who stay under water just for fun or to hunt for souvenirs, are disturbing the natural cycles of marine life.
POLLUTION One of the biggest threats to oceans is pollution from industry. Most pollution happens in coastal areas. In fact, many coastal cities and ports are reported to have long been polluted by chemicals and other harmful things from heavy industries. The industries dump these materials into the nearby rivers, which then wash them into the sea. Once they settle on a continental shelf, pollutants pile up. We do not know a great deal about the long-term effects of pollution. However, we do know that the North and Black Seas in Europe have been polluted so much that the marine life is poisoned and may never recover.
