The problem has led to efforts to “rewild” places where such life existed before human development, pollution and climate change forced it out. The American city of Detroit is an example of how human actions can increase rewilding, which generally means helping natural systems in damaged locations, removing dams or building tunnels to reconnect animal pathways cut by roads.

Detroit’s population reached a high of 1. 8 million in the 1950s. Then the population began dropping. By 2000, there were fewer than one million people living in the city. Thousands of houses and other buildings were left empty over the years. Some structures were destroyed, leaving empty areas that plants and animals regained as habitats. Nonprofit groups have also planted trees and community gardens in these areas. Bald eagles found their way back as bans on DDT and some other insect poisons were put in place nationwide. Anti-pollution laws and government-supported cleanups made nearby rivers better for fish and native plants.

Now, Detroit is home to 300 bird species and is a busy visiting place for ducks and others during migration. Additionally, this city offers a special way to study plants and animals in urban settings. Unlike most big cities, its population is decreasing but its streets and buildings remain in place. And there are many kinds of habitats, including large lakes, rivers and human neighborhoods. Detroit’s parklands are so quiet that people don’t even know they’re in the city.

“It used to be that you had to go to some remote location to get exposure to nature,” said John Hartig, a professor of University of Windsor. “Now that’s not the case. Like it or not, rewilding will occur. The question is how we can prepare communities and environments to anticipate the presence of more and more wildlife. After all, many city people have lost their tolerance to live with wildlife. To really make a difference in dealing with the biodiversity crisis, you’re going to have to have people on board. ”

They were all Welsh Corgis and were so cute with their little legs, long bodies and heads that looked too big for their bodies. It took me a long time to figure out which one I wanted, but I finally decided when the female came up to me and licked (舔) my face. I named her Dion.

It took a while for Dion to get used to our home. Every night, she cried in a way that made me burst into tears. She cried almost every second of the day. But after a couple of weeks, she got used to us. That's when we began to train her.

My mother and I took Dion to puppy kindergarten. It was funny to see all the disobedient (不温顺的) dogs. They all barked (吠叫) very loudly, making my ears hurt. The only one who didn't bark was Dion. She was very shy and hid from people. But she was very friendly with the other dogs. The trainer says that she is doing very well for a four-month-old puppy.

If you are thinking about getting a dog, consider all the time and effort you must put in. There are a lot of responsibilities . I walk Dion four to six times a day. I feed her, spend time with her and watch her when she is out of her doghouse. Even if my favourite TV programme is on, or a good part in a movie is coming up, I still have to take care of her. It is a lot of work to keep her clean. Sometimes when I brush her I end up with hair all over me.

However, it is all worth it. I have benefited in many ways from having Dion around. For one thing, she provides constant love. She is always there to lick me, lie on me and comfort me. I always have someone to keep me company. I enjoy playing with her. Dion is always there to talk to. Even though she doesn't talk back, I think she can tell when I am happy, sad, angry, confused or troubled.

Dion is a big responsibility but she is the most comforting friend because she is always there, with me.

【推荐3】Thai wildlife officials have laid out a plan to bring peace to a central Thai city after at least a decade of human-monkey conflict （冲突）.

The monkeys that hang around Lopburi are a major tourist draw. But after years of conflicts with residents and visitors, and several failed attempts to bring peace with population controls, local people and businesses have had enough.

The monkeys often try to take food from humans, sometimes leaving people with injuries. In March a woman got her knee hurt after a monkey pulled her off her feel, and another man was knocked off a motorcycle by a hungry monkey.

The authorities hope to catch some 2,500 monkeys and place them in massive wildlife preserves, said Athapol Charoenshunsa, the director-general of the Department of National parks, Wildlife and plant Conservation. They’ll work with wildlife experts to find a way for a limited number of monkeys to stay freely in the city, he added.

“I don’t want humans to have to hurt monkeys, and I don’t want monkeys to have to hurt humans,” he told reporters during a news conference in Bangkok. “I expect the first period of the operation to start within weeks, and I believe the wildlife preserve will be able to contain （容纳） thousands of them and will solve the problem very quickly.”

Athapol said they are also working in other areas of Thailand that are facing problems with monkeys. He said 52 of the country’s 77 provinces often report monkey problems.

The monkeys are said to be a symbol of the province, about 140 kilometers north of Bangkok, where the ancient Three Pagodas temple celebrates a yearly “Monkey Buffet” festival. However, some have complained about the city’s monkey troubles on tourists and residents feeding the animals, which they say drew monkeys into the city, helped with their numbers, and got them used to getting food from humans.

【推荐1】Stores play music to change the way customers feel. Clothing stores for teenagers play popular music. It is exciting and makes the customers feel happy, but music does more than that. It can change the way a person shops.

According to studies, the volume (音量) of music changes how people shop. Customers shop quickly when store music is very loud. They hurry through the store, but they buy just as much. When music is quiet, customers shop slowly. Customers take time to look at the products and talk with the salespeople. Quiet music is good for products that take time and information to buy.

Slow music makes people slow down. In restaurants with slow music, customers spend more time eating. Slow music also slows down customers in supermarkets. Customers notice more products as they walk through the store. With slow music in supermarkets, sales go up by 38 percent.

Familiar music gives shoppers a good idea of time. People know the beginning, middle, and end of a familiar song. When customers hear music that is not familiar, they don’t notice the time. When they don’t notice the time, they spend more time shopping and buy more. People remember past experiences and feelings when they hear familiar music. Many stores play old, happy music so customers feel good. When customers hear new music, they forget about the world outside of the store. Some stores use new music so their customers relax while they shop.

Stores choose music that fits their products. A bookstore plays classical music and jazz. It gives the store a serious and intelligent feeling.

【推荐3】As 3D printing technology improves, people keep finding new uses for it. And the latest is pretty sweet: cheesecake. Researchers with the department of mechanical engineering at Columbia University created a seven-ingredient slice of cake using a 3D printer, and they say printing foods could be a new cooking option with several benefits.

Such printers have been used to make organs before, and similar technologies already exist in the food space 一like pizza and bread robots, pasta printers and automatic cake decorators, the researchers say in the study, published in the NPJ Science and Food journal.

The researchers defined printed food as“the controlled deposition(沉淀), of an ingredient; as such, any ingredient that was pushed into paste(酱),” and they say many existing processed foods can be considered “printed” by this definition. So, in order to make the 3D-printed peanut butter -banana cheesecake with a cherry coat, all the ingredients had to be converted into paste-like substances. All seven ingredients were put in to the 3D printer and then printed out in layers into the shape of a piece of cheesecake.

The researchers say 3D printing food could allow cooks to control the nutrient content in a meal and also offer the ability to make more customized meals. It also reduces human contact with food, which could prevent the spread of food-borne illnesses and diseases.

They also see sustainability benefits to printing food, because ingredients can be locally sourced, plant-based meals can be created and the shelf life of the foods could be extended.

Printing food could also help people with swallowing and other digestive disorders,by providing new food options, rather than the bland foods they may be restricted to.

While some processed foods could have better taste, texture, cleanliness and shelf lives, processing foods can also degrade their nutrients. However, the researchers hope developing the 3D printing technology can help prevent nutrient degradation while processing foods.
