Humankind’s growing need for food is running up against thousands of other species’ need for space. By 2050, humans may need to clear an additional 3.35 million square
2 . On Feb. 21, four students were standing on the side of Pacific Coast Highway in Malibu when a driver going 110 miles per hour lost control of his car and it crashed into the parked vehicles.12 people were killed at the scene, including 2 drivers.
This kind of traffic death shouldn’t be called an accident. In Los Angeles, we seem to have accepted constant carnage (屠杀) in our streets in exchange for maximizing driver speed and convenience. The official responses to proven traffic dangers are mere gestures, if even that.
Los Angeles is a uniquely deadly city with a death rate that is four times the national average. Unsurprisingly, it’s also a city that has been designed with one thing in mind: a concept called level of service, which grades streets on how well they serve those in automobiles. To many Angelenos, that makes sense — to design our streets for car traffic, which is the way many get around the city. Unfortunately, we don’t recognize that there’s a trade-off. We can either have streets bettered for free-flowing traffic, or we can design streets for people to move around safely outside of cars.
City leaders consistently choose for the easy but deadly option. In one recent example, a resident asked the city’s Department of Transportation to block drivers from using Cochran Avenue at Venice Boulevard as a cut-through street, as they were speeding through a quiet residential neighbourhood. The department responded by suggesting a “speed awareness campaign” in which neighbours put up yard signs urging drivers to slow down.
People don’t drive based on signage, but they drive on the design of the street. The trunk roads of Los Angeles such as Venice Boulevard all need to be revised so that people are prioritized over cars. This would include narrowing travel lanes (道), building bike lanes, and banning right turns at red lights. These measures would make drivers feel like they’re in a city and not on a highway. A recent John Hopkins study says this would have substantial safety benefits.
With more than 7,500 miles of streets in the city of Los Angeles, they won’t all be rebuilt anytime soon. But with each road construction project, or each crash, we should be revising streets to make them safer for all road users.
The solution to traffic jam isn’t to make more space for cars. It’s to design the streets to be safe enough for alternatives such as biking, walking and mass transit, especially for the 50% of trips daily in Los Angeles that are less than three miles. The solution to protecting people dining outdoors isn’t crash barriers. It’s a street design that forces drivers to go slowly. The problem is carnage in the streets, and we know the solutions.

7 . A new study by scientists at Utrecht University concludes that about half of global wastewater is treated, rather than the previous estimate of 20%. Despite this promising finding, the authors warn that treatment rates in developing countries are still very low.
Humans and factories produce vast quantities of wastewater per day. If not properly collected and treated, wastewater may severely threaten human health and pollute the environment.
The authors use national statistics to estimate volumes of wastewater production, collection, treatment and reuse. “Globally, about 359 billion cubic metres of wastewater is produced each year, equivalent to 144 million Olympic-sized swimming pools,” says Edward Jones, PhD researcher at Utrecht University. “About 48 percent of that water is currently released untreated. This is much lower than the frequently announced figure of 80%.”
While the results show a more optimistic outlook, the authors stress that many challenges still exist. “We see that particularly in the developing world, where most of the future population growth will likely occur, treatment rates are falling behind,” Jones explains. “In these countries, wastewater production is likely to rise at a faster pace than the current development of collection and treatment basic facilities. This poses serious threats to both human health and the environment.”
The main problem, especially in the developing world, is the lack of financial resources to build basic facilities to collect and treat wastewater. This is particularly the case for advanced treatment technologies, which can be extremely expensive. However, the authors highlight potential opportunities for creative reuse of wastewater streams that could help to finance improved wastewater treatment practices.
“The most obvious reuse of treated wastewater is to increase freshwater water supplies,” Jones states. Treated wastewater reuse is already an important source of irrigation water in many dry countries. However, only 11% of the wastewater produced globally is currently being reused, which shows large opportunities for expansion.
“But freshwater increasing is not the only opportunity,” says Jones. “Wastewater also has large potential as a source of nutrients and energy. Recognition of wastewater as a resource, opposed to as ‘waste’, will be the key to driving improved treatment going forward.”
However, the authors stress the importance of proper monitoring of wastewater treatment factories, accompanied by strong legislation (法律) and regulations, to ensure that the reuse of wastewater is safe. The authors also acknowledge public acceptance as another key barrier towards increasing wastewater reuse.

Gather a couple of friends and take a leisurely walk through the streets—this is
When Kylie
Crystal breathed in the sweet January air. It was a cold, sunny day. Sunlight shone between the branches and fell onto the street.
It was so quiet, this neighborhood. Wandering down the road at a leisurely pace, Crystal noticed an open curtain in the window of one neighbor. They were busily typing on their home network. Remote workers, obviously.
Crystal’s glance shifted to a kid who had just come home from school. He looked down to the cell phone in his hand.
“Hey，kid!” Crystal waved.
The boy didn’t raise head, some game keeping his attention.
Crystal sighed and closed her eyes. It took her back to when she was a little girl back in the late 1980s. Neighbors knew each other by name then. Crystal’s best friend Anne was the next door neighbor. They often played for hours using imaginary names for far-off places, pretending to be or do something they hoped someday they could be or do.
Nowadays, to pretend to be somewhere else, you could just click on some random program for a virtual reality video of Italy or Australia, and your wish was instantly satisfied. You could do that alone. And if you needed a person to chat with, you could pick a random person in your interest group online.
“You don’t need neighbors anymore,” Crystal commented to herself.
And yet, there is so much that can be missed for the simpler times. Those who grow up not knowing the invisible person-to-person simplicity of being a good neighbor, have missed an entire piece in their maturity. It’s not about personal space. It’s about being there for another person. How could a metal chip replace a life? Crystal could never understand.
As she turned onto her home sidewalk, she noticed a little girl about 5 years old looking confused and afraid. There was no coat on her thin arms. Must be some neighbor’s girl. Crystal was very concerned. W here were her parents?
“Are you alright, honey?” Crystal asked.
1. Why did the boy give no response to Crystal?2. What did Crystal do with her next door neighbor in her childhood?
3. Decide which part of the following statement is wrong. Underline it and explain why.
▶Crystal believed that technology advanced and the relationship with neighbors mattered less than before.
4. What do you think the relationship between neighbors should be like nowadays?(In about 40 words)
