Ryan Hickman is only seven years old, but he’s already been saving for his college fund with profits he’s making from his recycling business.

When Ryan was three-and-a-half, he went with his dad to the local recycling center and made money from a few bags of cans and bottles. When he learned money can be made from that, Ryan decided recycling was his future.

“We had gone to the center with a couple of bags, and he really loved the actual act of putting all the cans and bottles into the machine and getting the money from it, and that kind of act got him hooked, ” described Damion Hickman, Ryan’s father.

Ryan told his parents that he wanted to give empty plastic bags to all the neighbors and hoped they would save their recyclables for him. Not only did the neighbors save their cans and bottles for Ryan but so did their co-workers, families, and friends. Soon after, Ryan started his own business, Ryan’s Recycling, and has since recycled over 200,000 cans and bottles. Every week, he and his family sort through bags of recyclables and they take them to the local recycling center where they are sorted and weighed.

So far, Ryan has saved more than $ 10,000 for college from his profits and he also sells T-shirts on his website and donates the profits to the Pacific Marine Mammal Center in Laguna Beach. “For the sea lions to get food and medicine,” he said.

Ryan has an important message for everyone, “If you already recycle, just keep on recycling. If you don’t recycle, start recycling.” Always a great businessman, Ryan added, “If you want to buy one of these T-shirts, it’s $ 13 on ryansreecycling.com.”

   Dragging a sleigh loaded with enough presents for the world’s children can be no easy skill. But, since ancient times, the Christmas Eve duty has been performed by a team of beloved reindeer.

Soon, however, Santa Claus may have to start looking around for a stronger type of animal, as newresearch shows the species is becoming increasingly puny. A 16-year survey on the arctic Norwegian islands, Svalbard, found the reindeer there have declined in weight by an alarming 12 percent.

The reduction in average body weight is being blamed on global warming. In the research presented lately at a meeting of the British Ecological Society in Liverpool, scientists have explained how upward temperatures are robbing female reindeer of nutrients during important periods of pregnancy.

Snow in Svalbard typically covers the ground for eight months of a year, which, combined with low temperatures, limits grass growth to June and July. But as summer temperatures increase by around 1. 5℃, grass has become more productive, allowing female reindeer to gain more weight by autumn and therefore to have more babies. However, winters have brought with them greater rainfall which freezes when it settles on the snow. Reindeer can often access the poor food sources beneath the snow by clearing it away with their antlers (鹿角) , but they cannot break through the hard ice. As a result, female reindeer are becoming starved, causing them to lose their babies or give birth to the much lighter young.

Despite the findings, reindeer appear to be suffering less from the effect of climate change than some other arctic species. Last week the scientists warned that a third of the world’s polar bears could disappear in the next 40 years.

Can you imagine wear a pretty sweater made from garbages? It could happen! A few companies across the country are making clothes from things that are being thrown away by people. For example, company makes sweaters of old plastic bottles. First, the bottles are cut into small pieces. The pieces are melted. Then the melting plastic is made into long and thin threads. The threads are used to make sweaters which feels very soft and light.

Believe it or not, these sweaters sell good in spite of the fact which they are not cheap at all. Many people thought that these recycled clothes can help us cut down on garbage.

In many countries today, laws protect wildlife. In India, the need for such protection 【小题1】（realize）centuries ago. About 300 years ago, 【小题2】 Indian writer described forests 【小题3】   were somewhat like national parks today. The killing of animals was 【小题4】（careful）supervised（监督）. Some animals were fully protected in the forest. Nobody was allowed 【小题5】（cut）timber（木材）, burn wood for charcoal, or catch animals for their fur. Animals which became 【小题6】（danger） to human visitors were caught or killed outside the park, so that other animals would not become uneasy.

The need for wildlife protection is 【小题7】（great）now than before. About a thousand species of animals are in danger of dying out, and the rate at which they are being destroyed 【小题8】（increase）. If we don't take 【小题9】（measure）to protect wildlife,some day our children will see no living creatures 【小题10】 themselves.

   Caroline Solomon was on her high school's swim team. But at times she could not go into the creek（小溪）near her home. It was simply too polluted. "I decided I wanted to do something about it，"she recalls. So she studied environmental science and public policy at Harvard University in Cambridge. Later，she went to graduate school. Some of her classes could be challenging，though，since she couldn't hear her teachers. "I've been deaf since I was 15 months old，"Solomon notes.

Today she teaches biology at Gallaudet University in Washington，DC. She has no trouble communicating with her students. They，too，are primarily deaf or hard of hearing. That's why all classes at Gallaudet are taught in American Sign Language. Solomon also has an active life outside the classroom. She especially enjoys hiking，biking and other activities with her family.

Her research takes her to the Anacostia River. "It is very close to Gallaudet，and I easily bring my students there，"she says. Water running through local forests and marshes drains into this river，so does water running off urban streets，golf courses and industrial sites." The river's watershed（流域）kind of concentrates all the things that happen when humans mess with the natural landscape，"she explains. Not surprisingly，this river has developed a reputation for being quite polluted.

Solomon has been focusing on how pollutants affect tiny organisms that form the base of the river's food web. "I am now looking at the bacteria population，" she says，"to see what types there are."

Solomon wants to see more students who are deaf or have other disabilities make a difference in environmental science and other fields. As she often says, "If I can do it, you can do it."
