Read the following article and answer the question. Article: Some of the planet's most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction. The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians . Who is to blame? Scientists believe that 99 percent of threatened species are at risk because of human activity. "We are losing animals and plants at a high rate," says Julia Marton-LefEevre, director general of the IUCN. "We need to change our behavior." Warmer oceans and over-fishing are changing sea life. This year for the first time corals made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim of habitat destruction. Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. "This shows that protection methods can work," says Marton-LefEevre. "That's the message we want to send to young people." In China the new reserve itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed. "The country's natural resources have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said. The total areas of China's natural reserves have covered 1.38 million km2, which accounts for 15.4% of China's area, higher than both the world average of 11% and the rate in most developed countries.

Read the following article and answer the question. Article: If you're a male and you're reading this, congratulations: you're a survivor. According to a survey, you're more than twice as likely to die of skin cancer than a woman, than nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you'll die on average five years before a woman. There're many reasons for this -- typically, men take more risks than women and are more likely to drink and smoke--but perhaps more importantly, men don't go to the doctor. "Men aren't seeing doctors as often as they should," says Dr. Gullotta. "This is particularly so for the over-40s, when diseases tend to strike." Gullotta says a healthy man should visit the doctor every year or two. For those over45, it should be at least once a year. Two months ago Gullotta saw a 50-year-old man who had delayed doing anything about his smoker's cough for a year. "When I finally saw him it had already spread and he finally died from lung cancer," he says. "Earlier detection and treatment may not have cured him, but it would have prolonged his life." According to a recent survey, 95% of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group. "A lot of men think they can never defeated," Gullotta says. "They only come in when a friend drops dead on the golf course and they think, 'Geez, if it could happen to him, ...'" Then there's the ostrich approach. "Some men are scared of what might be there and would rather not know," says Dr, Ross Cartmill. "Most men get their cars serviced more regularly than they service their bodies," Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups. Regular check-ups for men would inevitable place strain on the public purse, Cartmill says. "But prevention is cheaper in the long run than having to treat the diseases. Besides, the ultimate cost far greater; it's called premature death." Question: Why does the author congratulate his male readers at the beginning of the passage? Answer:
