Thirteen hundred tons of fuel oil were flowing right in the middle of the Afric
10、an Penguins? habitat. Soon the oil covered about 20,00（） penguins. Without swift help, the seabirds would have no chance for survival. Volunteers were showing up by the thousands and I also took part in what was the largest animal rescue operation ever.A warehouse was turned into a rescue center nea
11、r the habitat and hundreds of pools were built to hold about 100 oiled birds each. When walking into the center, I couldnt believe my ears. I had expected to walk into a chorus of honking and squawking（叫 声）. Instead, the center sounded like a library. The penguins were dead silent. My heart ached fo
12、r the painful birds. Cleaning them all seemed like an impossible task. But we had to carry on like doctors in an emergency room. There was no time for doubt. Cleaning oil off a penguin wasnt easy. Even with more than 12,500 volunteers, it took a month to bathe all 20,000 birds at the center.While vo
13、lunteers were busy bathing the oiled penguins, another crisis（危机） was developing. Oil from the spill had started moving north. Tens of thousands of penguins were in the oils path. But we already had our hands full with 20,000 recovering birds. If any more birds were oiled, we wouldnt have enough res
14、ources to save them.One researcher came up with an idea: What if the penguins were temporarily moved out of harms way? Experts decided to have a try. Volunteers rounded up the penguins and released them 500 miles away. The hope was that by the time the seabirds swam home, the oil would be gone. The
15、plan worked! Another 20,000 penguins were saved.The entire penguin rescue took about three months. More than 90% of the oiled penguins were successfully returned to the wild. Looking back on the rescue, I am still amazed by the work of the volunteers. What I could hardly believe was that we accompli

18、the influence of a T-shirt on the planet? Youd probably be surprised to loam whafs involved in the lifecyle of just one T-shirt.There are 5 major stages: material, production, shipping, use and disposal（处理）. The material stage involves farming, irrigating, fertilizing, harvesting and ginning. While
19、colton is a natural fiber and not as harmful lo the environment as manmade fibers, it still takes a toll in the material and production stages. Commercial cotton farming uses a large amount of water, and the use of pesticides（杀虫剂）is widespread across the globe, especially in cotton farming. Studies
20、have shown that farmers spend around $4.1 billion on pesticides annually, of which 25% was spent on cotton crops in the US.Once the cotton is grown and harvested, so begins the production stage: spinning, knitting, bleaching, dyeing, cutting, sewing, etc.these processes also use a great deal of wate
21、r and energy. Commercial dyes and bleaches are harmful pollutants and can eventually pollute groundwater.After the T-shirt is produced, it enters the transportation stage. This often involves overseas shipping. Take a look in your closet. Chances are most of your cotton garments（衣月及）are made in Chin
22、a or India. Garments can be shipped via plane, ship or truck., all of which spill CO2 into the atmosphere. Calculations show that CO2 emissions from light trucks alone amount to 1.15 pounds per mile.Once the T-shirt reaches the retail market, it is purchased. This stage may seem like the least envir
23、onmentally damaging part. But consider the number of times youve washed and dried your favorite T-shirt. Washing machines are certainly becoming more efficient. However, the average American household does 400 loads of laundry per year, using about 40 gallons of water per load. Such excessive water
24、use is combined with the large amount of energy used by dryers.The final stage of life is disposal. This releases harmful emissions, or involves a landfill where cotton takes years to break down. Current U.S. records show that an estimated 15% of clothes and shoes are recycled, which means that cons
25、umers send a shocking 85% of these materials to landfills.We all need new clothes every once in a while, but lets all try to keep in mind what goes into the production of clothing. it has a real impact on the planet.There are a lot of things you can do to help reduce your impact. Reuse and recycle c
26、lothes. If theyre too worn out to wear, cut them up and use them as cleaning rags. Donate them to charity or another organization that recycles textiles. When possible, make an effort to buy organic cotton. Turn down the thermostat（恒温器）onyourwasher, and line dry your clothes when the weather will al

To introduce the five stages in the lifecycle of clothing.DWhat is the most meaningless thing every Texan will do at the same time thisweekend?You guessed it. We will fall back when our clocks are set backward one hour in observan
31、ce of daylight saving time.This strange practice has an interesting history. In 1784, Benjamin Franklin published a critical essay in a French newspaper suggesting that Parisians could save $200 million through “the economy of using sunshine instead of candles”. Therefore, many people owe the origin
32、 of the idea of daylight saving time to our Founding Fathers writings. In the United States, the clock-changing practice began just over 100 years ago, in 1918, when Congress decided to control time by passing the Standard Time Act to save energy and create time zones. Back then, coal was our top en
33、ergy source and ensuring that Americans had more daylight working hours made sense.In 2008, the U. S. Department of Energy assessed the effect of observing daylight saving time on national energy consumption. It found that resetting our clocks amounts to a reduction in our total energy consumption o
34、f 0. 02%. The study also delermined that sticking with one time could actually save about （）.5% of electricity per day nationwide. Apart from this, the risk of heart attack increases 10% in the days following springing forward, most likely caused by the interruption of biological rhythms. Studies al
35、so indicate we are more likely to get sick, we are less productive, and frankly we are just exhausted directly following the time change.Il is hard to explain why we still change our clocks. Perhaps it is due to special interests. Congress passed the Energy Act of 2005, which extended the length of
36、daylight saving time an extra week in the fall, in large part due to an effort by candy producers to allow for an additional daylight hour on the night of Halloween for trick - or - treating.This May, we sought to end this ancient practice. It would have allowed Texans to vote whether to stay on sta
37、ndard time year-round or daylight saving time year-round. Our proposal passed the House（众议院）133-9. Sadly, once the bill reached the Senate（参议院）,it was never referred to a committee. The proposal died in the Senate without even a word spoken about it on the floor.Im moving forward with plans to file
38、the legislation again in 2021. I urge you to contact your state legislators to move this legislation forward so that this weekend will be one of the last times we have to “fall back.”31.
