【推荐1】Best Parks to See Wildlife

A recent report from a vacation site listed the total number of species and sizes of several well-known national parks. Here are some of them to see the widest variety of animals.

Cuyahoga Valley National Park, Ohio

Number of species per square meter: 317

Located 20 miles southwest of Cleveland, Ohio, Cuyahoga Valley National Park is a mixed ecosystem of forest and wetlands sheltering a variety of animals. From the boardwalk at Beaver Marsh, watch for water-loving mammals or snapping turtles (鳄龟) that can weigh as much as 55 pounds each. More than 200 bird species live in the park.

Carlsbad Caverns National Park, New Mexico

Number of species per square meter: 286

The representative for Carlsbad Caverns is the Brazilian free-tailed bat. Every summer, hundreds of thousands of the furry, big-eared creatures live in these caves in southeastern New Mexico, attracting crowds at sunset with their spectacular out flight. The Brazilians are one of the 17 bat species that nest at Carlsbad. You might also encounter wild pigs and cave swallows.

Acadia National Park, Maine

Number of species per square meter: 242

The Atlantic Ocean meets the Maine coast at this popular park on Mount Desert Island, providing habitat for wildlife with feet and flippers (鳍状肢). From the shore, scan the water for the heads of harbor porpoises (鼠海豚) and gray seals.

Black Canyon of the Gunnison National Park, Colorado

Number of species per square meter: 219

In western Colorado, the 2, 722 feet between this park s canyon edge and the Gunnison River below support numerous wildlife habitats. Experienced climbers and hikers who adventure into the inner canyon find collared lizards and mule deer.

Previous theories say light probably blinds flying insects so that they get trapped by the light, or maybe they interpret light at night as a place to fly for a quick escape. Now the new study suggests flying insects instead turn their backs to the sky’s light to keep their feet pointing toward the ground. Insects naturally turn their backs toward light. But when that light is from an artificial source, it may affect their sense of direction, leading to them flying in circles or diving toward the ground.

At a field station in Costa Rica, Samuel Fabian, an entomologist from Imperial College London in England and his teammates set up hanging and standing lights, and then used high-speed cameras to track wild, flying insects including moths and flies. Some circled the lights endlessly, and others flew sharply upward, losing speed until they couldn’t fly any higher. When the light source pointed up, some insects turned around and headed for the ground. During the flight, the insects always kept the lights at their back even if they’d end up crashing. Crash landings were common when the team lit up a white sheet on the floor. But not when a white sheet — stretched into a height above the floor—was bathed in diffuse (漫射) light, much as the sky would be, insects flew through the area without getting trapped by the light.

The team also observed some species in a lab. Moths and dragonflies generally behaved like the wild insects, and they kept the light at their backs. However, in the lab, fruit flies, like oleander hawk moths — which can fly in the dark — could fly over LED lights without being thrown off course. In the wild, though, the moths still crashed. Maybe this is because, Fabian says, the insects can sometimes control their response to light, or over time, they might learn to avoid artificial light.

【推荐2】A Lesson from the Elder

Grandfather was an elder Cherokee Native American who had a wrinkled, nut brown face and kind dark eyes. His grandson often came in the evening to sit on his knee and ask the many questions that children ask.

One day the grandson came to his grandfather with a look of anger on his face and the following story. “Father and I went to the store today and because I helped him, he bought me a present — a jack-knife. I went outside to wait for father and to admire my new knife in the sunlight. Some town boys came by and saw me. They surrounded me and started saying bad things. They called me dirty and stupid and said that I should not have such a fine knife. The largest of these boys pushed me back and I fell over one of the other boys. I dropped my knife and one of them picked it up and they all ran away laughing. I hate them. I hate them all.”

The elder Cherokee, with eyes that had seen too much, lifted his grandson’s face so his eyes looked into the boy’s face. Grandfather said, “Let me tell you a story. I, too, at times, have felt a great hate for those who have taken so much with no sorrow for what they do. But hate wears you down and does not hurt your enemy. It is like drinking poison and wishing your enemy would die. I have struggled with these feelings many times. It is as if two wolves are inside me...

It is a terrible fight.

One wolf is good and does no harm. He lives in harmony with all around him and does not take offense when no offense is intended. It will only fight when it is right to do so and in the right way. This wolf stands for joy, peace, love, hope, sharing, modesty, kindness, friendship, sympathy, generosity, truth, and faith.

The other wolf is full of anger. The littlest thing will set off his fiercest temper. He fights everyone, all the time, for no reason. He cannot think because his anger and hate are so much.

It is helpless anger, for his anger will change nothing. This wolf represents fear, envy, greed, self-pity, guilt, lies, false pride and superiority.

Sometimes, it is hard to live with these two wolves inside me for both of them try to control my spirit. This same fight is going on inside you and inside every other person too.”

The boy looked into his grandfather’s eyes and asked, “Which wolf will win?” The old Cherokee simply replied ...

“The one you feed.”

【推荐1】For a long time, I kept a selection of books on a shelf next to my bed that I called my “heart books”. To qualify for a place on the shelf, a book had to be not only one I loved, but one that mattered. There was one book that never made it onto that shelf, though I read it in high school: Writing Down the Bones by Natalie Goldberg.

I can still remember the day I bought it. It was summer and I must have been 14 or 15. Desperate to get out of my house, I rode my bike into town and walked into the bookstore. I was going through the shelf of books on writing and it caught my eye. I picked it up, read a few pages, and bought it. Then I took it with me to a park, read the first few chapters, and opened my notebook to write.

It’s a fairly straightforward writing book. Goldberg’s method is simple: you choose a topic, set a timer, and write for 10, 15, or 20 minutes without picking up your pen. Free writing, timed writing, writing topics: anyone who has taken a creative writing class may have encountered these things. It’s not earth-shattering. There was nothing particularly new or unusual about the book so I can’t say why it attracted me so much. But it changed everything. I went from being someone who enjoyed writing to being a writer.

During my teen years and early twenties, following Goldberg’s method was at the core of my identity. No matter where I was or what I was doing, I filled notebooks. When I eventually started writing fiction, I did the same thing. The “I” in my notebooks became someone else, but I held to the same practice.

This writing practice led me to a writing group in Boston. It led me to my current career. It led me, in so many ways, to myself. Becoming a writer allowed me to become so many other things: an activist, a business owner, a farmer, a baker. . . Writing is where I found my confidence. It was where I became curious about the world. From that, everything else has followed.
