Article: We know that cigarette smoking kills. So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco. Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them. They are powered by battery . However, if e-cigarettes are so safe, why has the United States Center for Disease Control(CDC) seen an increase in telephone calls about e-cigarette poisonings? The answer is children. Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns. More than half of these calls were for children aged five and younger. The devices had made them sick. Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation. Meaning, the U.S. federal government does not control e-cigarettes even though they contain liquid nicotine. Mr.McAfee adds that liquid nicotine is a well-known danger. Mr.McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed. It can cause stomach pain or a sense of unbalance. And too much nicotine can kill, Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do.He notes that almost 500,000 Americans die each year from cigarettes. "So, cigarettes are the winner in that contest." E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes. So, the U.S.Surgeon General Boris D. Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use. But McAfee worries that teenagers may think electronic cigarettes are harmless. They could become addicted to the nicotine and then start smoking real cigarettes. In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing.
Answer: Cheaper.

Article: The Arctic Fox Characteristics The arctic fox is dark gray to bluish brown in the summer. In the winter its fur is white or creamy white. It has a long bushy tail, a short nose and small, curled back ears. It has short legs and thick fur. Its short legs and nose, thick fur and small ears are adaptions that help it survive in cold climates. Because its legs are so short and its ears and nose are small, they are less exposed to the cold. The arctic fox also has thick fur and hair on its paw pads that help keep it warm. When the arctic fox is sleeping, it protects its nose from the cold by curling its bushy tail around its body. The arctic fox is about three feet long and weighs between five and fifteen pounds. Males are larger than females. Diet The arctic fox is an opportunities eater. It will eat just about whatever it comes across. It eats small mammals like lemmings and it also eats birds, insects and eggs. In fact, in the winter it often follows polar bears and wolves and eats their leftover kill. In the summer the arctic fox will carry extra food to its den and store it under rocks to eat later. The arctic fox sometimes even makes its own freezer by digging a hole in the permafrost and storing its food there. A major source of food for the arctic fox is the lemming. In fact, the arctic fox population often peaks every four years in a cycle that follows lemming population changes. Life Cycle The arctic fox mates between February and June. The female builds a new den and gives birth to between six and twelve dark--furred kits. Both the female and the male will take care of the young kits. The male will guard the den and bring food to the den for the mother and the kits. The kits are weaned when they are between two and four weeks old and then they will start to leave the den.
Answer: It is difficult to hunt lemmings as food.
