Guide to Hiking on the Appalachian Trail

How do I “Leave No Trace on the Appalachian Trail?”

At about 2,189 miles, the Appalachian Trail is the longest single unit of the National Park System. With the number of people visiting this place increasing each year, the chances are great that any of us may damage the natural environment along the Trail and affect the experience for others. So please do your part by following these hiking and camping practices, and encourage others to learn about and adopt these techniques.

1. Plan ahead and prepare.

Evaluate the risks associated with your outing, identify campsites and destinations in advance, and use maps and guides. Prepare for extreme weather, dangers, and emergencies — especially the cold — to avoid impacts from searches, rescues, and campfires. Learn when areas are most crowded and try to avoid those times.

2. Dispose of waste properly.

Pack out all trash and food waste, including that left behind by others. Don’t bury trash or food, and don’t try to burn packaging materials in campfires. Use the privy (茅房) for human waste only. Do not add trash. If there is no privy, dispose of human waste by burying it in a hole, a hole at least 200 feet (80 steps) from campsites, water sources and shelters, and well away from trails.

3. Leave what you find.

Leave plants, cultural artifacts (器物) and other natural objects where you found them for others to enjoy. Do not damage live trees or plants; green wood burns poorly. Collect only firewood that is dead, down, and no larger than your wrist. Leave dead standing trees and dead limbs on standing trees for the wildlife.

4. Minimize campfire impacts.

Use stoves for cooking — if you need a fire, build one only where it’s legal and in an existing fire ring. Keep fires small. Never leave your campfire unattended, and drown it when you leave. Do not try to burn trash, including plastic, glass, cans, tea bags, food, or anything with food on it. These items do not burn thoroughly. They create harmful fumes (烟雾), and attract wildlife like skunks and bears.

5. Respect wildlife.

Don’t feed or disturb wildlife. Store food properly to avoid attracting bears, varmints, and rodents. If you bring a pet, keep it leashed (用皮带系住).

Before the Internet age, critical thinking was the most important skill of people. But in the digital age, according to Anastasia Kozyreva, a famous psychologist, a more important skill is critical ignoring (批判性忽略).

As researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with many eye-catching stories while providing little useful information, so they can offer us advertisements producing profit (利润). So we are not customers but products, and each link we click is a sale of our time and attention. To protect ourselves from this, Kozyreva calls on us to learn the skill of critical ignoring, in which readers can control their information environment to reduce exposure (接触) to false information.

According to Kozyreva, critical ignoring includes three strategies. The first is to design our environments, which includes removing low- quality y et hard-to-resist (难以抵制的) information from around. Successful dieters need to keep unhealthy food out of their homes.’ Similarly, we need to set up a digital environment where attention-catching items are kept out of sight: Like dieting, if one tries to depend on willpower not to click eye-catching “news”, he’ll surely fail. So, it’s better to keep them out of sight at first!

The next is to judge the reliability (可靠) of information, whose purpose is to protect you from false information. It can be realized by checking the source in the mainstream, which can be reliable.

The last is: “never feed the trolls.” Trolls are some people who spread false information online to cause harm. Do not correct them, because they do not care about whether the information is correct. Annoying others is their goal. So, ignore their bad behaviour.

By using the above critical ignoring skills, we can make the most of the Internet while avoiding being harmed by those who try to control our attention, time, and minds.

【小题1】What can we learn about the attention economy from paragraph 2?
A.It offers more information.B.If offers depressing stories.
C.It saves time for Internet users.D.It goes after profits from each click.
【小题2】Why does the author mention dieters in paragraph 3?
A.To explain the power of will.B.To prove the benefits of healthy food.
C.To show the importance of environments.D.To discuss the quality of information.
【小题3】What should we do to deal with Internet trolls according to the text?
A.Review their aim.B.Turn a deaf ear to them.
C.Correct their behaviour.D.Send hard facts to them.
【小题4】What is the text mainly about?
A.Strategies for Internet users to apply critical thinking.
B.Reasons for critical thinking in the attention economy.
C.Practising the skills of critical ignoring in the digital age.
D.Increasing the benefits of critical ignoring on the Internet.
