Article: . As the world's largest terrestrial carnivore ,the polar bear is the king of the great white north. Adult males can measure more than 9 feet in length and weigh between 770 and 1,430 pounds. The bear's body and neck are elongated, and the head is narrow and long with small, rounded ears. Polar bear populations can be found in northern Canada, Greenland, Norway and Russia, and there have been reports that polar bear tracks have been found as far north as the North Pole. The 5,000,000-square-mile range of the polar bear circles the Arctic and contains stretches of open water where seals are easily caught. Polar bears live on the annual Arctic sea ice that provides a platform from which they can hunt. They hunt seals on the sea ice by breaking into seal dens in the sea ice. The dens aren't visible from above,but seeing is less important than smelling to a polar bear -- with their keen sense of smell,polar bears can sense the breathing holes of seals in their dens beneath the snow and ice. As the southern edge of the Arctic ice cap melts in summer, polar bears are stranded on land and spend their summers fasting ,living off body fat stored from hunting in spring and winter. It might come as a surprise that this species faces an uncertain future. Climate change is causing the disappearance of sea ice from which polar bears hunt seals. Sea ice in the Arctic is melting earlier and forming later each year. With about 22,000 polar bears living in the wild,the species is not endangered at the moment, but its future is far from certain. People have reached an agreement that controls the hunting of polar bears and directs each nation to protect their habitats, but it does not protect the bears against the biggest man-made threat to their survival : global warming. If current warming trends continue, scientists believe that polar bears may disappear within 100 years.

Article: Thirteen-year-old Greg Hoffman had been begging his parents for an iPhone all year. So on Christmas morning he was thrilled to find the object of his desire under the tree, but there was a _ . The phone came with an 18-point set of terms and conditions that he had to agree to before the phone could be his. And the agreement did not come from Apple or the phone provider, it was from his mother. His mom, Janell Hoffman, included a contract along with the iphone that listed eighteen conditions or rules that Greg has to follow if he wants to keep it. Some of the rules limit the time he can use the phone; not after 7:30 p.m , and he can't take it to school. He also has to promise not to send "hurtful" text messages and e-mails to people; give his passwords to his parents, and always answer the phone when his mom or dad calls. Greg also has to use his own money to replace the phone if it's broken or lost Janell says the idea behind the contract is to teach her son to have a sense of responsibility and to learn to "co-exist with technology, not be ruled by it'. She told him not to use this technology to lie, fool, or cheat another human being. Most of the terms do not just apply to the iphone, but to life. She also advised him to, "keep your eyes up. See the world happening around you," "Stare out a window. Listen to the birds. Take a walk. Talk to a stranger. Wonder without Googling." "You are growing up in a fast and ever changing world. It is exciting and enticing. Trust your powerful mind and giant heart above any machine. I hope that you understand it is my job to raise you into a well rounded, healthy young man that can function in the world and coexist with technology, not be ruled by it," "I love you. I hope you enjoy your awesome new iPhone. Merry Christmas!"

Article: An old man in a faded yellow shirt sat in a windowless room on a raised concrete form. The only source of heat came from somewhere beneath the plastic mattress and the rough blanket the blank-faced police woman had handed him after taking his thumb prints. He heard voices and metallic clang as the cell door swung open. At the front desk a tired looking policeman handed the old man back his belongings, his worn-out cap and the Seiko watch that had stopped working the day his beloved Evelyn left. The policeman dramatically held the blue plastic bag at an arm's length to the old man who took it and made sure its contents were undamaged: the goat meat, palm oil, leaves and spices. He ignored the confused expression on the officer's face and signed the document declaring he had been returned the possessions they had taken off him the night before. No one spoke to him as he walked slowly towards the exit. "Mr. Easy-nwa?" He stopped and prayed to the God who now took care of Evelyn to please take him far away from this unhappy place of expressionless faces, clipped accents and people who did not even attempt to pronounce his name right. "Ezenwa," He said and looked at a woman with tangerine lips, her name tag said Jessica Harlow, Social Services. "A bit far from home,,,she said as she drove fast and with confidence the way Evelyn used to. He wondered if she meant the 50 miles from Liverpool or the 50,000 miles from Enugu,a city in Nigeria. He did not bother replying as this woman had plenty to say about the weather, bad drivers, her daughter's school play... At last she drew up outside the block of flats where he lived. "Got here in the end",said she seriously, "Really Mr. Easy-nwa, if you keep getting lost, we will have to consider moving you into a home". "No need, I was not lost,,,he answered. He carefully rolled up the sleeves of the oversize bomber jacket he wore and turned on the tap to wash his hands, relieved the pipes were not frozen. In a clean pan he placed the chopped pieces of goat meat. The herbs and spices that had taken him three months to track down, the uziza seeds had taken him into the heart of Granby Market in Liverpool, his uchanwu leaves down a shady back alley in Manchester, and yesterday, among other food items, the finest goat meat from a Sierra Leonean Butcher in Birmingham. That had taken some time, so much he missed the last train and when the police found him shivering outside the locked up station, so cold he couldn't answer loudly enough the pink-faced big copper who yelled in his face, "What's your name sir?" spraying his face with spittle as he did so, leaving them with no choice but to search an exhausted, frozen old black man and finding him in possession of mysterious condiments including a bag of dried bitter-leaf which could of course be mistaken for anything that resulted in him getting read his rights and charged with ...possession??? He lifted the lid of the bubbling soup, the room was filled with the rich and spicy scent of his culinary effort. He served two bowls, taking the chipped one and placing the other opposite where Evelyn would have sat. He would tell her about his adventure, it was their anniversary and this was the perfect pepper soup to celebrate. Ken Onyia, UK (Nigeria) Commonwealth Sport Short Story Prize
