La Tomatina, Spain

    Tomato juice flows through the streets of Bunol on the last Wednesday of August as the worlds largest tomato fight happens. Festivities begin in the town square where there is a huge pole covered in soap and with a leg of ham at the top. Participants try to climb up the pole to get the ham as watchers throw buckets of water to them. After a gun is fired to signal the beginning of the fight, people catch the tomatoes and throw each other in the streets until the gun sounds again, marking the end of the event.

    Holi, India

    This spring festival is celebrated throughout the country in late February or early March. The two-day event celebrates the legend of Prahlad, who escaped unharmed from the fire of the evil Holika Dahan. People mark the event by lighting fires and throwing colored powder on one another Children load colored water into toy pistols called pichkari and take aim at passers-by. Holi is known as a happy celebration of the victory of good over evil.

    Burning Man, Nevada

    This infamous festival began in 1986 with the burning of a large figure to mark the summer solstice (夏至). It's since grown into a week-long annual event that draws more than 48,000 people to the Black Rock Dessert. It is held during the week before Labor Day. Participants set up camp in the desert to celebrate art.

    Songkran, Thailand

    This festival marks the Thai New Year, which is celebrated in the second week of April. This is the hottest time of the year in Thailand, so it makes sense that the biggest Songkran tradition is to throw water on people. Thais of all ages join in water fights, using buckets, hoses (软管) and water guns to celebrate the event.

    Every year, billions of kilograms of fresh produce are wasted in the United States. Meanwhile, millions of poor Americans go hungry, without access to healthy and affordable meals. Evan Lutz, CEO and founder of Hungry Harvest, was inspired to act after seeing extreme poverty in areas of Baltimore, Maryland. He wants to reduce the so—called food waste in that area. His work is to make sure no food goes to waste and no person is ever hungry in America. And he combines that goal with a love for business.

    Hungry Harvest is a business which collects and sells fruits and vegetables that most food companies will throw away. Everything doesn't grow the same way on a farm. But all that is too big or too small gets thrown out. That is why everything in a grocery store looks similar. Hungry Harvest will box those imperfect ones and deliver them to customers once a week.

    For every purchase, Hungry Harvest delivers healthy food to people in need. Hungry Harvest has recovered 300,000 pounds of produce to date and provided 100,000 pounds to those in need.

    Lutz established Hungry Harvest in 2014.Its success depends on team work. Every week on Monday or Tuesday they will decide what will go into the next week's box by calling up packing houses and wholesalers to see what they will normally throw away that week. They then place the order. The last step ls to send goods to customers.

    In January 2016,Lutz appeared on the American business competition television show "Shark Tank" and got even more than he expected: $100,000.Lutz is using the money to expand. Actually, more than six billion pounds is wasted each year due to "ugly" surface. Hungry Harvest is on the way to saving more food from going to waste and feeding hungry families.

    I work with Volunteers for Wildlife, a rescue(救援) and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival(存活) is never certain. However, when it works, it is simply beautiful.

    I got a rescue call from a woman in Mutton town. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2­to-3­week­old owl. It had already been placed in a carrier for safety.

    I examined the chick(雏鸟) and it seemed fine. If I could locate(定位) the nest, I might have been able to put it back, but no luck. My next work was to construct(建造) a nest in a tree.

The homeowner was very helpful. A wire basket was found. I put some pine branches(松树枝) into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

    Now all that was needed were the parents, but they were nowhere to be found. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

    A nervous night to be sure，but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded(回应) to the recordings. I drove over and saw the chick in the nest looking healthy and active. And with it was the greatest sight of all — LUNCH！The parents had done their duty and would probably continue to do so.

    In the U. S. state of Washington, a road called Interstate(州际公路；州际的)90 cuts through a wild mountainous area to reach the city of Seattle. For the area's many kinds of animals, busy high- way greatly limits their movements. Animals need to move to find food, to find mates, to find new places to live as their populations expand or just when conditions change, like a fire breaks out. Crossing I-90 – as the road is called – is a risky but sometimes necessary act. But soon, animals will have a safer choice. They will be able to go above it.

    To help the animals, the state is finishing work on its largest - ever wildlife bridge. The 11-meter-tall, 20 - meter - wide bridge begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing anti plants to help guide the animals across the bridge, Two-meter-thick walls will help block noise from vehicles below. Scientists chose the area because it is within a natural migration(迁徙)path for some animals.

    The I -90 bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges，and some are underpasses. They all aim to keep drivers and animals away from each other.

    A U. S. Transportation Department study found crashes between animals and humans rose year by year. The accidents made up about 5 percent of all crashes nationally, and cost the economy (经济)about ＄8 billion. Such costs come from car repaid, emergency room visits and removal of the dead animals on roads. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. The study also found that 21 endangered or threatened species in the U.S. are affected by vehicle hits. Bridges, underpasses and fencing reduce I he area's animal - driver collisions by 80 percent.

    Most of the wildlife bridges are in western states. Many other areas also need such paths. But finding money for more crossings is "the- number - one problem". Patty Garvey — Darda of the U. S. Forest Service has worked on the I - 90 crossing from the start of the project. She says the $ 6 - million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. "If you shut clown Interstate 90, you shut down interstate trade." she adds.

    I'm not so sure I like my friends any more. I used to like them — to be honest. We'd have lunch, talk on the phone or exchange e-mails, and they all seemed normal enough. But then came Facebook and I was introduced to a sad fact: many of my friends have dark sides that they had kept from me.

    Today my friends show off the more unpleasant aspects of their personalities via Facebook. No longer hidden, they're thrown in my face like TV commercials — unavoidable and endless advertisements for the worst of their personalities.

    Take Fred. If you were to have lunch with him, you'd find him warm, and down-to-earth. Read his Facebook and you realize he's an unbearable, food-obsessed bore. He'd pause to have a cup of coffee on his way to save a drowning man — and then write about it.

    Take Andy. You won't find a smarter CEO anywhere, but now he's a CEO without a company to lull. So he plays Mafia Wars on Facebook. He's doing well — level 731. Thanks to Facebook, I know he's playing about 18 hours a day. Andy, you've run four companies — and this is how you spend your downtime(业余时间)? What happened to golf? What happened to getting another job?

    Take Liz. She is positive that the H1N1 vaccine(甲流疫苗) will kill us all and that we should avoid it. And then comes Chris who likes to post at least 20 times a day on every website he can find, so I get to read his thoughts twice, once on Facebook and once on Twitter.

    In real life, I don't see these sides of people. Face to face, my friends show me their best. They're nice, smart people. But face to Facebook, my friends are like a blind date which goes horribly wrong.

    I'm left with a dilemma. Who is my real friend? Is it the Liz I have lunch with or the anti-vaccine lunatic(狂人)on Facebook? Is it the Fred I can grab a sandwich with or the Fred who weeps if he's at a party and the wine isn't up to his standards?

Most of Bangladesh is at or below sea level. Rising seawater linked to climate change has severely affected the country. High water from storms in coastal areas also adds salt to soil. The land is becoming salty. Crops are less productive and many areas of cropland in the country are becoming unfit for farming. These are big problems for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.

To find a way out，farmers in the country are learning to grow vegetables in so-called "vertical gardens". The soil in these gardens is better because heavy rains have removed much of the salt.

A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain (排水).

The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.

The farmers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This "vertical tower" measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12—$13 to build.
