3 . Overlooking the Davis—Gant Varsity Soccer Field, a bed of overturned soil waits for further development. In a few years, this area will become a natural habitat and a playground for animals and residents. This peaceful area didn’t appear naturally, but through planning and action taken by Catlin Gabel’s Tiny Forest project launched by teacher Patrick Walsh.

Forests typically take hundreds of years to mature, with four stages of growth. “Tiny forests flatten out time through the planting of all four layers (层),” Walsh explained. The end result is a fast-growing, native forest in about 20 years. Over 600 plants from 43 species will be planted in the tiny forest, the first one in Oregon.

Walsh was inspired to build a tiny forest after hearing about this idea, which emerged in Japan and has taken hold in North America. He shared his vision with seniors in his class. The seniors researched tiny forests and made a proposal resulting in Clean Water Services donating 60 trees and $5,000 from the National Oceanic and Atmospheric Administration. Armed with these resources, Walsh and the students started working. “Something I didn’t really expect was the outpouring of students’ enthusiasm. Seeing students from all grades volunteered to contribute to the ‘dirty work’ really blew me away,” Walsh said.

Senior Megan Cover has been at the school since the first grade. “I’ll graduate after working on this project, which is surely sad, but it’s really rewarding and great to be a part of this project and to do my bit. We’re creating this educational space for many young kids,” Cover said.

Walsh summed up his goal of the project, which is to build a place where students can enjoy and learn about nature. “The forest will obviously not solve climate change, but it will deserve the efforts if the kids think about climate change and remember the importance of reforestation and trees when they look outside at the forest.”

4 . Be a Green Child

What does it mean to be green? “Green” is more than just a colour.     1     Why green? Plant are green, and without them the Earth wouldn’t be such a lovely home for us human beings. Every day, people make choices that affect the amount of rubbish and pollution produced in our world. What can we do? Here’s a four-step guide to being green:

Reduce It!

    2     For example, a shorter shower means you use less water and less fuel(燃料) since your house uses fuel to run the water heater that warms up the water.

Reuse It!

Sometimes people call ours a “throwaway society”. That means that we re a little too willing to throw away old things and buy new ones.     3    For example, if your baby brother outgrows his plastic basketball hoop, why not give it to another family who has a little kid?

Recycle It!

Recycling has never been easier. Many communities will pick it up right in front of your house and some towns even require it. Recycled goods go to a recycling centre, where they can be turned into new cans, bottles, and paper.

Enjoy It

It’s true that rubbish and pollution are problems, but the Earth remains a huge and beautiful place that’s ready for you to explore.     4     Go for a hike, visit local nature centres and gardens, and climb up mountains. But before you travel the globe, take a look at your own backyard. Is there a place where you could plat a tree or put in a little fruit or vegetable garden?     5    

A．If so, get out there and get your hands dirty.

B．Turn off the water when you’re brushing your teeth

C．You can watch with pride as your garden plants grow.

D．It also means taking special steps to protect the environment.

E．When you use less of something, you do a good thing for the Earth.

F．You can start locally by visiting the naturally beautiful places in your cities.

G．Many times, even if you no longer need something, someone else just might.

5 . I first realized that plastic was a serious matter for our planet during my travel in Western Australia. One day about 12 years ago, I stopped at a supermarket along the Coral Bay coast ta buy some groceries. But the lady at the counter told me that the supermarket didn’t sell any shopping bags to prevent plastic in the ocean and help preserve the endangered turtles(海龟) living in that area. After a first reaction of surprise, I gathered all purchases in my arms and left, reflecting on what I had been told.

The experience in that trip made me more conscious about my impact and pushed me to adopt various habits to travel and live more sustainably. For example, I always carried a cotton bag when I went shopping.

My travel to Indonesia was another life-changing experience that strengthened my determination to turn to a zero-waste lifestyle. In Indonesia, finding safe drinkable water was always a challenge, so I traveled with my water bottle, managing to avoid almost entirely the use of plastic during my trip.

However, I was seriously struck by my stay on the Libaran Island, where a sustainable and turtle conservation project was launched 10 years ago. Despite the big efforts by the project staff and the community in cleaning up the beaches and creatively reusing plastic, the shore was washed daily with tons of plastic coming from the tides. Walking on a carpet of plastic that almost prevented me from seeing the beach underneath was quite shocking.

Facing this global issue in person, I felt a sense of sadness and anger that soon turned into determination: to do as much as possible to reduce plastic in my life. Sometimes we might feel helpless in front of big problems, but we should be aware that small changes could actually make a difference step by step!

7 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

8 . Tips for Green Travel with Kids

Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.     1    

It’s easy when travelling to pull in to fast food restaurants for snacks.     2     My kids love to help plan snacks. I let them create their own snacks for the trip at home.

    3     At the airport, keep your reusable bottles empty until you have passed through the security (机场安检区). Fill them up on the other side of the security checkpoint. Single-use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

    4     In addition, opening a few windows and turning off the air conditioner (空调) are also good ways to save energy. You should also help your children keep their good, green habits while travelling. Sometimes vacation can mean more than one shower each day-once in the morning and again after getting out of the pool. Pay attention to the number of showers (淋浴) and the length of showers.     5    

A．Walking is good for your health.

B．Try to cut back to save water and energy.

C．But you can pack healthy food from home.

D．Travelling is a great chance to introduce your kids to the world.

E．Reusable water bottles are easy to bring along wherever you travel.

F．Save energy by turning off the hotel room lights when you head out for the day.

G．You might have to drive a bit farther, but saving on carbon emissions makes it worthwhile.

9 . Plastic straws (吸管) have been a major problem in global discussions of environmental damage. Maybe because of their small size, the production cost of straws is low. In many countries, straws are offered freely after buying soft drinks. Therefore, plastic straws are one of the most used plastics and pollutants in the world.

The plastic straw is light and small. Due to their small size, plastic straws are often eaten by sea animals. Environmentalists have shown that the death of many sea animals is caused by eating plastic straws. The other damaging characteristic of plastic straws is that they are made of materials which cannot degrade. That means the materials cannot be changed into small harmless (无害的) ones.

The most effective way of dealing with the environmental pollution caused by plastic straws is the reuse or banning (禁止) the use of plastic straws. Being plastics, the straws can be made new items. Many organizations around the world change used straws into new products. In Africa, local communities collect used plastic straws and use them to make mats and bags. Another way of dealing with environmental pollution caused by plastic straws is placing a ban on their production and use. Experts advise governments to ban using plastic straws to save the environment. A few countries in the world such as Rwanda, Macedonia, China, Kenya have already banned the use of plastic bags and are expected to include plastic straws and bottles. But it will be a long way to do this effectively.

There are few environmentally friendly and biodegradable productions to take the place of plastic straws. These productions include paper straws, bamboo straws. However, such straws are usually expensive as their production cost is high. It’s still a question whether they can entirely take the place of plastic straws.

1. Why can people be free to use plastic straws?

A．They are very cheap.	B．They are light and small.
