1 . When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.
The fur trade kept nutria in check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashion. Model Paige Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them-I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She is trying to come up with a label to attach to nutria fashions to show it is eco-friendly.
What is the purpose of the fashion shows in New Orleans and Brooklyn?| A．To promote guilt-free fur. |
| B．To expand the fashion market. |
| C．To introduce a new brand. |
| D．To celebrate a winter holiday. |
3 . The green, natural forest absorbs carbon dioxide from the air through photo- synthesis (光合作用). There is another way of dealing with the climate crisis. That is setting up fields of dark-colored solar panels (太阳能电池板), also known as “solar forests”, which replace power stations that use fossil fuels such as coal and gas to make electricity, thus mitigating harmful emissions (排放) of greenhouse gases.
But since they are both relatively dark, they absorb a lot of solar radiation. Some of the energy is used for photosynthesis in natural forests or to produce electricity in “solar forests”, but most returns to the atmosphere, heating it up. Then what would be the more effective land use option in terms of the climate crisis: planting a forest, or building solar panels? This issue has long been debated by decision-makers around the world. Now, we may have an answer, thanks to a new study.
First, the researchers compared the impact of a forest on the climate crisis in a dry area to that of a solar farm in a similar environment. The researchers found that the albedo effect (反射效应) of both of these “forests” was similar, but that the absorption or prevention of carbon emissions was very different. It turns out that it takes 2.5 years for the heat emitted by solar farms to be balanced by the carbon emissions that are avoided, thanks to the energy they produce. In the case of a natural forest of similar size, it would take more than 100 years of photosynthesis to balance its heating effect.
The researchers also studied how the heating-cooling relationship changed in other climates and found that in more humid environments, the heating effect of planting large numbers of trees is smaller. And the break-even point is reached within 15 to 18 years.
“In dry places, building solar forests seems far more effective in addressing the climate crisis. Meanwhile, forests absorb about a third of annual carbon emissions and play a vital role in the global rain cycle, in maintaining biodiversity and in many other environmental and social contexts. Preventing them from being cut down and planting more trees in humid areas are of great significance,” explains one of the researchers in the study.
What did the researchers find in the study conducted in the dry environment?| A．The natural forest exhibits a stronger albedo effect. |
| B．The solar forest can generate more energy in dry areas. |
| C．The solar forest is superior in balancing the heating effect. |
| D．The natural forest is more effective in solving the climate crisis. |

5 . Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush. Through her own efforts, her letter was reproduced on over 250 donated billboards across the country.
The response to her request for help was so huge that Poe established Kids For A Cleaner Environment (Kids F.A.C.E.) in 1989. There are now 300,000 members of Kids FACE worldwide and is the world's largest youth environmental organization.
Poe has also asked the National Park Service to carry out a "Children's Forest" project in every national park. In 1992, she was invited as one of only six children in the world to speak at the Earth Summit in Brazil as part of the Voices of the Future Program. In 1993, she was given a Caring Award for her efforts by the Caring Institute.
Since the organization started, Kids F.A.C.E. members have distributed and planted over 1 million trees! Ongoing tree-planting projects include Kid's Yards – the creation of backyard wildlife habitats (栖息地) and now Kids F.A.C.E. is involved in the exciting Earth Odyssey, which is a great way to start helping.
"Starting the club turned out to be a way to help people get involved with the environment. Club members started doing things like recycling, picking up litter and planting trees as well as inviting other kids to join their club."
"We try to tell kids that it's not OK to be lazy," she explains. "You need to start being a responsible, environmentally friendly person now, right away, before you become a resource-sucking adult."
