We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

    Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don't keep reducing emissions(排放) of carbon dioxide (CO₂ ) and other greenhouse gases that are trapping heat in our atmosphere.

    We decided to try an experiment. For one month we recorded our personal emissions of CO₂. We wanted to see how much we could cut back, so we went on a strict diet. The average US household(家庭) produces about 150 pounds of CO₂  a day by doing common-place things like turning on air-conditioning or driving cars. That's more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?

    For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man is Changing the Climate and What it Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化) of the ice sheets in Greenland or West Antarctica. "To stay below that point, we need to reduce CO₂  emissions by 80 percent," he said.

    Good advice, I thought. I'd opened our bedroom windows to let in the wind. We'd gotten so used to keeping our air-conditioning going around the clock. I'd almost forgotten the windows even opened. We should not let this happen again. It's time for us to change our habits if necessary.

    It was a cold night in Washington, D. C., and I was heading back to the hotel when a man approached me. He asked if l would give him some money so he could get something to eat. I'd read the signs "Don't give money to beggars." So I shook my head and kept walking.

    I wasn't prepared for a reply, but he said, "I really am homeless and I really am hungry! You can come with me and watch me eat!" But I kept on walking.

    The incident bothered me for the rest of the week. I had money in my pocket and it wouldn't have killed me to hand over a buck or two even if he had been lying. Flying back to Anchorage, I couldn't help thinking of him. I tried to rationalize (找借口)my failure to help by thinking government agencies, churches and charities were there to feed him. Besides, you're not supposed to give money to beggars.

    Somewhere over Seattle, I started to write my weekly garden column for The Anchorage Daily News. Out of the blue, I came up with an idea. Bean's Cafe, the soup kitchen in Anchorage, feeds hundreds of hungry Alaskans every day. Why not try to get all my readers to plant one row in their gardens dedicated to Bean's? Dedicate a row and take it down to Bean's. Clean and simple.

    The idea began to take off. Readers would fax or call me when they got something in their garden. Those who only grew flowers donated them. Food for the spirit.

    In 1995, the Garden Writers Association of America held their annual convention in Anchorage and after learning of Anchorage's program, Plant a Row for Bean's became Plant a Row for the Hungry. The original idea was to have every member of the Garden Writers Association of America write or talk about planting a row for the hungry sometime during the month of April.

    As more and more people started working with the Plant a Row idea, new changes appeared unexpectedly. Many companies gave free seed to customers and displayed the logo, which also appeared in national gardening publications. Row markers with the Plant a Row logo were delivered to gardeners to set apart their "Row for the Hungry."

    Garden editor Joan Jackson, supported by The San Jose Mercury News and California's nearly year-round growing season, raised more than 30,000 pounds of fruits and vegetables her first year, and showed GWAA how the program could really work. Texas fruit farms donated food to their local food bank after being inspired by Plant a Row. Today the program continues to thrive and grow.

    I am surprised that millions of Americans are threatened by hunger. If every gardener in America--and we're seventy million strong--plants one row for the hungry, we can make quite a decrease in the number of neighbors who don't have enough to eat. Maybe then I will stop feeling guilty about abandoning a hungry man I could have helped.

    Are you carrying too much on your back at your back at school? I'm sure lots of children of your age will say “Yes”. Not only the students in China have this problem, but children in the United States also have heavy school bags.

    Doctors are starting to worry that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.

    “It's hard for me to go upstairs with my bag because it's so heavy,” said Rick Hammond, an 11-year-old student in the US.

    Rick is among students who have common school bags with two straps（带子）to carry them, but many other students choose rolling（有滚轮的）bags.

    But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.

    But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight.

    Scout Batch, a back doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don't stay with over 15%, because their bodies are still growing.

    “Children are losing their balance and falling down with their school bags,” he said.

    Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.

    One of the best answers is, as some children said, to have no homework at all!

    Seventeen-year-old Sariah Estrada didn't expect to receive anything in return when she saved a drowning man on Marianne Beach in Blanchisseuse earlier this year.

    However, for her random act of kindness, Estrada was awarded the Hummingbird Medal-Bronze for her bravery, loyalty and devotion to Trinidad and Tobago on Monday, September 24, when the country celebrated its 42nd year as a republic. President Paula-Mae Weekes presented the national award to her.

    In July of this year, Estrada along with two friends went to the Marianne Beach to relax. Upon leaving the beach, Estrada and her friends noticed a man struggling in the water. Immediately, she and her friends sprang into action. The teens borrowed a body board from some people on the beach and swam to the man's rescue.

    She said when they reached the man, he was already unconscious and they dragged him out of the water on the body board. Estrada remembered what she learned during a life-saving course the week before and quickly started pumping the man's chest. After several attempts，she was successful and the young man's life was saved.

    In an interview with LoopTT, the teenager said while she is grateful for the award, she wasn't expecting anything in return.

    "This award was never expected because I thought of helping someone as an act of humanity and never looked for anything in return, but the award is well appreciated. As I reflect on the action I took, I felt as though I could help this person as I have the proper training. The week before the incident I participated in a basic life support-training course offered by the North Central Regional Health Authority." Estrada explained. She said she intends to continue assisting people.

    The national award receiver also had this message for the youths of Trinidad and Tobago.

    I would like to encourage the young people of Trinidad and Tobago to strive for excellence, never sell yourself short by believing that you cannot do what you desire, all things are possible and hard work surely brings success."

    Recently, American President Trump announced his budget. One of the budgets would cut all money to the Institute of Museum and Library services and libraries across the United States. However, as far as I'm concerned, we need to save our libraries.

    Libraries provide books and after-school programs for children. They encourage literacy (识字）with summer programs. They help inspire a life-time love of learning and reading in children of all ages. Without them, where will kids with no Internet at home do their homework? Where will kids have a place to study or borrow books after school? Therefore, we need libraries for our kids. We need them so that kids can grow up with a place, other than school , where learning and exploration is encouraged. For adults, libraries serve as a place where they can use the Internet to apply for jobs, get job training, early voting centers as well as book clubs to help make new friends. It can also serve as a place to pick up a book and learn something new. What's more, they can also borrow a book and get away from it all.

    Libraries save our information for the next generation. When we live in an age of alternative (选择性的）facts, where science is ignored in favor of personal feelings, we need libraries now more than ever. We need them to educate ourselves on the facts and hold the government responsible for them. We need them to have strong public participation.

    If you agree with me, you shouldn't be silent on this issue. You can write or call directly to tell the president to save our libraries. You can also write to both your state Senators (参议员）and your district representative. If you do not know who they are, you can find out here. Let them know this is a beneficial issue because all people use public libraries in their daily life.

That morning in September, at a five-kilometer race, I waited for my 11-year-old son at the finish line. He'd run 30:34 at another 5k in late spring, so I 1 he could run a 5k in about 30 minutes. When I didn't see him at the 35-minute mark, I began to 2 .

It'd already been an 3 morning. About an hour earlier, when we drove into town, my son noticed a lovely tiny green tree cricket （树蟋） in my car. It jumped onto my son's hand where it stayed so long that we eventually gave it a name: Little Friend.

Minutes before the race, it jumped onto the sidewalk. Maybe it wanted to seek freedom, but this wasn't a safe place due to the 4 pedestrian traffic. So my son knelt and 5 his hand. Little Friend came back. But I told him he would 6 it during the race.

I ran well and felt thrilled at the finish line. However, that 7 gave way to anxiety when my son didn't show up. I 8 asking people if they'd seen him. No one had. So I returned to the race headquarters. In my confusion, I didn't even see him 9 the finish line. But there he was, just ahead of the 45-minute mark, with Little Friend 10 on his right thumb.

My 11 were wrong. My son didn't run fast, and he didn't lose Little Friend. These two 12 seemed somehow related. He 13 a cold he was getting over, but I knew it was more than that.

Sometimes life gives you something beautiful, but fragile （易碎的）. There's no need to 14 ahead. Treat it 15 and hold on when you can.
