Urban ( 城市的 ) heat kills about 600 Americans every year, andsends another 65,000 to the emergency room, according to a recentreport from the Urban Land Institute. Climate change is going tomake these problems worse, the report's authors write.
Given that risk, Boston — like many cities around the country —plans to plant more trees. Urban trees have benefits beyond shadingand cooling. They clean the air, reduce noise pollution and helpprevent flooding by absorbing storm water."Great," you might be thinking, "let's plant many trees."
Unfortunately, the solution isn't that simple; a lot of street trees don'tmake it more than a few years in the big city. "It's tough to be a babystreet tree because their roots are really little. And the summers inBoston are quite hot, so drought alone can kill them," says AndrewTrlica, who recently earned an urban biogeochemistry doctorate fromBoston University.
An urban tree, especially one planted on a sidewalk bordering abusy street, has many factors against it. "Cars run into them. Bikesgetting locked to them is really surprisingly damaging when they'relittle because their bark (树皮) is weak," Trlica explains. "Road saltsare hard on their roots. Dogs would pee on them. It's just a toughenvironment."
Trlica says he began to wonder: If city officials want to increasetree canopy (树冠) cover to deal with climate change, should theyfocus on planting new trees or helping older ones survive? To figureit out, he looked at two conditions for Boston: spend the next twodecades planting saplings (树苗) in every available sidewalk location,or spend the time reducing the mortality rate of older trees by 50%.
For Trlica, the answer was clear. Yes, Boston should continueplanting trees, but the real canopy payoff will come from preservingbigger, leafier ones.
Diet Coke, diet Pepsi, diet pills, nofat diet, vegetable diet....We are surrounded by the word "diet" everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brains to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, highcalorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale (秤) instead. All we have to do is to swallow or recognize the word "diet" in food labels.
On another level, diet products have greater psychological effects. Every time we have a zerocalorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consumingthem instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous. Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological and physical harm that comes from using them.
Overweight people produce more greenhouse gases, researchers say. Therefore, watching your weight does more than protect your health. It also may help fight climate change.
Researchers at the London School of Hygiene & Tropical Medicine say that because food production is a major source of greenhouse gases, a population with normal weight, such as in Vietnam, consumes about 20 percent less food and produces fewer greenhouse gases than a population in which 40 percent of people are too heavy and fat, a rate close to that of the United States.
Also, less energy is required to transport slim people. say Phil Edwards and Ian Roberts, the lead researchers of the study.
They found that a physically fit population of a billion people would give off 1,000 million tons less transportationrelated wastes a year than an overweight population would give off. "When it comes to food consumption (消耗), moving about in a heavy body is like driving around in a car that burns a lot of gas, " the researchers said. "The heavier our bodies become, the harder and more unpleasant it is to move about in them, and the more dependent we become on our cars. Staying slim is good for health and for the environment."
"We need to do a lot more to stop the global trend toward fatness and recognize it as a key factor in the battle to reduce greenhouse gases and control climate change, " they said.
However, they noted that the trend is in the opposite direction. The number of overweight people is increasing in nearly every country. The male who were overweight in England, for example, increased from 20 percent to 27.3 percent between 1999 and 2009, while the female increased from 25.8 percent to 29.6 percent.

For me, two of the loveliest words in English are "Life persists".
I1 them years ago as a college student, sitting in the library, 2, working on a paper. Out of nowhere, those words came 3 off the page in a quote: "In the midst of death life persists; in the midst of 4 truth persists; in the midst of darkness light persists."
Suddenly I wasn't unhappy and impatient any more. Then I called my granddad. I loved to talk with him. And I was5 to hear what he'd think of it. He had poor hearing, so I had to repeat it a few times, but once he 6 it, he laughed. "All I can say to that is totally7,"he said on the phone. I told him how glad I was, after a long winter, to finally see spring and 8 to find that quote. "Why is that?" he asked. "Well, spring is a sure 9 that life persists. And it just makes me 10."
He laughed again, and then in his lovely voice, he recited to me his11"spring time" words: "The desert shall rejoice(欣喜), and 12 as the rose."
Many years later,13 my husband and I drove across a desert with many wildflowers and blooming cactuses(仙人掌), I could almost hear my granddad laughing: "The desert shall rejoice."
Life persists, and so do we, in the silence of 14 and the blooming of cactuses;and in the dead of winter and the green of spring. Spring 15 us that we're alive forever.

Using reusable packaging (be) an important wayto cut packaging waste from the source, but only four out of the ninecompanies surveyed have taken (act) to put recyclableboxes into use.
In terms of the types of packaging recycled, the delivery companies(main) recycle paper boxes but plastic packaging hasnot been included in their recycling programs.
In June, the State Post Bureau released a guideline (manage) green packaging. The guideline calls for (use) reusable and lighter materials. It also urges companies to set uprecycling bins at delivery stations for wrapping.
