1 . Waste not, Want not
Today, I live in Manhattan with my husband, Alex. I’m an IT specialist and Alex is a lawyer. Life’s good, but sometimes I look at the way we live it and think of Ellie, my grandmother. Her favorite saying was “Waste not, want not.”
Such economy seems strange, even ridiculous, in our modern throwaway society, where everything is sold in boxes.

B.My grandparents threw almost nothing away |
C.In one week alone, we threw away five old magazines |
D.We didn’t often go shopping and then cook meals at home |
E.As young Manhattan professionals, we buy a lot of “convenience food” |
F.But we pay a high financial and ecological price for our lovely packaging |
G.If you placed all the cans used in the United States, in one year end to end |
Earth is home to millions of different species. Some can be very small, like bacteria and viruses, which are so small that we cannot see
3 . Human activity is changing the surface and temperature of the planet. But new research shows it is also changing the sound of the Earth’s oceans and seas.
Scientists say the changes in the sounds of our oceans and seas affect many marine(海洋) animals—from very small fish to huge whales. Sound travels “very far underwater,” Francis Juanes told the reporter. Juanes is an ecologist at the University of Victoria and co-writer of the recent research published in a magazine. “For fish,” he explained, “sound is probably a better way to sense their environment than light.”
Sounds help fish and other marine animals survive. They use sounds to communicate with each other. Sounds also help some ocean animals find food and avoid their hunters. Many ocean animals use sounds to find good places to give birth. However, increased noise from humans is making it harder for these animals to hear each other. The noise comes from shipping traffic, underwater oil and gas exploration, offshore construction, and other noisy human activity.
“For many marine species, their attempts to communicate are being masked by sounds that humans have produced,” said Duarte. The marine ecologist at the Red Sea Research Center co-wrote the paper with Juanes. The Red Sea, Duarte said, is one of the world’s most important shipping passages. It is full of large ships traveling to Asia, Europe, and Africa. Some fish and other animals, he said, now avoid the noisiest areas. Also, the overall number of marine animals has gone down by about half since 1970. In some parts of the ocean, scientists now record “fewer animals singing and calling than in the past—those voices are gone,” said Duarte.
Juanes and Duarte examined studies and research articles about changes in noise volume(音量) and frequency in the world’s oceans. Then they put together a detailed picture of how the ocean soundscape is changing and how marine life is affected.
Climate change, the researchers found, also affects physical processes that shape ocean sounds. These include such things as wind, waves, and melting ice.
Some studies suggest that noise may cause hearing loss of marine animals. Besides, many marine animals are showing higher levels of stress due to noise, which might also affect the immune(免疫) system.
Scientist Juanes says sound pollution may be easier to deal with than other ocean threats. “In theory,” he said, “you can turn down or turn off the sound immediately. It’s not like plastics or climate change, which are much harder to undo.”

6 . In January 1958, Rachel Carson received a letter from her fiend Olga Owens Huckins. Huckins lived in an area of Massachusetts where the state was trying to get rid of mosquitoes. They had used planes to spray a mixture of fuel oil and DDT (a pesticide, which can kill pests such as insects, weeds and rodents) all over the area around Huckins home. DDT was supposedly harmless but the morning after the spraying. Huckins found several of her favorite birds dead outside her house. And the spraying did not even kill all of the mosquitoes, in fact that summer there were more of them than ever before. Huckins asked Carson if she knew someone in Washington that could help prevent future spraying.
Carson had been hearing about DDT since a Swiss chemist discovered it could be used to kill insects in 1939. To many people, DDT seemed like a miracle substance. Farmers were excited about saving their crops from pests. Doctors and others were excited about saving people's lives by killing disease-carrying insects. But to Carson. DDT appeared to be dangerous to all living creatures.
The more Carson found out about DDT and other pesticides, the more she realized that she needed to help stop future spraying. Carson decided to write a book about pesticides. She said, “There would be no future peace for me if I kept silent.” She called her book Silent Spring.
Carson had spent her life studying, observing, and writing about nature. She was a trained biologist and a talented writer who knew how to present scientific information in compelling stories. Before Silent Spring, she had written other books from the perspective of fish birds, islands and oceans. Carson knew that all things in nature exist in a delicately balanced ecosystem. In Silent Spring, Carson wrote that. although the ecosystem can adjust to changes, it needs time. Carson believed that people u the 1950s were using pesticides carelessly Nature didn’t have time to adjust, wrote Carson, because so any pesticides had been used in such large quantities in such short tame.
