12、going to shine, I took an extra one,” he said. Exposure to the sun is the major source of vitamin D. However, people are spending less and less time outdoors in many areas. The problem is particularly serious in Scotland. "The Scots are the whitest people in the world because their entire body

13、systems are crying out for vitamin D," he said, adding that life expectancy in Scotland is two years shorter than in England or Wales. Multiple sclerosis (多发性硬化症), a medical condition which is often seen in northern Europe, is also higher in Scotland than in England. Vitamin D helps with the ab

14、sorption of Ca, which helps keep bones strong. And Jones said the fact that rickets (佝偻病) was making a comeback in Britain after nearly 50 years was another sign of how changing behavior patterns were bringing physical harm. Jones admitted that concerns over the damaging effects on skin of long-time

15、 exposure to the sun were reasonable, but said sunlight was healthy and necessary for the human body, and could help in lowering blood pressure. "If you lie on the beach for an hour, you will drop your blood pressure by about 10 points, because it relaxes your blood vessels (血管). So, get out in

However, the plastic in their lenses can linger (存留), polluting both water and land.Rolf Halden, an enginee

20、r at Arizona State University in Tempe, and his team created an online survey. More than 400 contact lens wearers took part. The questions asked how many got rid of their lenses inappropriately. About 20 percent one in five sent their used contact lenses down sink drain or toilet. Assuming all conta

21、ct lens wearers in the U. S. do that at the same rate, the researchers then calculated how much plastic would be flushed away each year. Their estimate: 6 to 10 metric tons! That's about the weight of two to three adult African forest elephants. Contact lenses are a tiny part of the world's

22、plastic pollution. But the unique plastic used in contact lenses could make them a big concern. To figure it out, researchers exposed contact lenses to the microbes (微生物) used to clean wastewater in water-treatment plants. These microbes made the plastics begin to fall apart, but they weren't fu

23、lly broken down. Instead, they created a lot of tiny pieces called microplastics. Halden worries that these small plastic bits will cause trouble in the food chain. In water, the plastics from contact lenses sink. Animals could view these tiny bits as food. But because the plastic won't provide

24、them with nutrition, this could threaten the health of animals who dined on it.And that's already happening. Many studies have shown that corals, larval fish and shellfish are mistaking microplastics for food. Over time, they risk accumulating even higher levels of plastic in their bodies. Also
