[Q]: Article: Great white sharks! Just hearing that name _ . In reality, these big fish have more to fear from us than we do from them. For many years, people killed countless great white sharks in the waters around the United States. But thanks to conservation efforts, great whites are making a comeback in the U.S. Two recent studies show that the population of these sharks is rising along the east and west coast. Why is the growing population of a killer fish something to celebrate? "When you fish too many of them, you start to lose balance in the environment," says shark researcher Tobey Curtis. As the biggest killer, sharks help keep the populations of fish, seals, and other creatures they eat from growing too large. In spite of their importance, great white sharks had long been hunted for their meat and their fins . Then, in 1997, the U.S. government passed a law that didn't allow the hunting of great whites. Afterwards, the numbers of these sharks in the U.S. waters started to increase. The law wasn't the only thing that has helped great whites. Conservationists have also played a part in the sharks' comeback. The research group OCEARCH is using a method called tagging to help change people's attitudes about great white. They let the public follow each shark as it travels the world's oceans. OCEARCH also gives each tagged shark a name to help people form a closer connection with the big fish. The group's most well-known shark is named Katharine. She was tagged last year near Cape Cod, Massachusetts. Since then, thousands of people have tracked Katharine's movements on Twitter and the OCEARCH website. This helps people see sharks in a new way. Chris Fischer, the founder of OCEARCH believes learning to appreciate great whites will encourage people to do more to protect them.

[Q]: Article: If you give something to someone for free, will that person value it and use it? Development experts have debated this question for decades. Some think the act of paying causes people to value something and use it more. Selling necessary health treatments, others argue, may deny them to the people who need them the most. Consider, for example, chemically treated bed nets, which kill mosquitoes anti protect people against malaria while they are sleeping. William Easterly, an economist at New York University, believes this is one example of development having gone wrong. In a recent book, Professor Easterly suggests bed nets given free in Africa are often used for the wrong purpose. Yet, the World Health Organization (WHO) recommends bed nets be given out free and used by whole communities. The success of a large free bed net campaign in Kenya led the WHO to announce this recommendation This debate will likely influence social programs in the developing world. Many non-governmental organizations support the creation of self-supporting programs in poor countries. Goods and services are sold for a price to help these programs survive. According to Rachel Glenerster, who runs a research lab doing development and poverty studies at the Massachusetts Institute of Technology, her several studies have proven that small price changes have a big influence on the number of people who use a product. A price change will reduce the total amount of use of the product as well, she says. She has also found no evidence that the very act of paying for something changes how people use it. As for a particular product among special populations, some development experts argue that pricing is useful. When it comes to bed nets, Miss Glenerster says research shows no evidence of this. People are just as likely to use a bed net whether they paid for it or not.
