Maybe you don't know the fact that the green forests we see from an airplane or from the highway can be false. Because centuries ago forests were twice as many as what they are today. A hike into many of those woods will tell different stories, too--of diseases and insects that are slowly killing trees, of some forests that are burned by fire, of logging that local people do more often. Deforestation  and degradation   of the world's forests mainly harm the basic ability of those ecosystems   to function or provide services, such as fresh water, air, plants and animals, which benefit people everywhere and keep the balance of nature.  Deforestation Forests today are a small part of what they once were. Nearly half of the world's forest cover is gone, and each year 40 million acres more are cut and replaced by agriculture and development. Over the next 45 years, wood use in the world is guessed to increase by 50 per cent over its present rate. Many of the forests that remain are severely destroyed, which harms the ability to protect birds or wild animals, and to supply natural resources to people. Deforestation also brings about between 20 per cent and 25 per cent of all air pollution causing global climate change. Degradation Forests continue to be degraded by some uses such as the gathering of wood for fuel, the arrival of pests and diseases that kill trees, the effects of climate change and poor management such as the fire, flood and so on. How many forests will be cut if we don't take measures after ten years? A) About 300 million acres of forests. B) About 30 million acres of forests. C) About 40 million acres of forests. D) About 400 million acres of forests.

Many drivers say the large digital billboards flashing ads every few seconds along Bay Area freeways are just too bright and too distracting. And they may be right. A Swedish study published in the journal Traffic Injury Prevention concludes that digital billboards hold the gazes of drivers longer than two seconds. Previous studies have shown that anything that takes a driver's eyes off the road for that length of time increases the risks of a crash. "This study proves what is common sense when it comes to digital billboards," says Mary Tracy, president of Scenic America, a national nonprofit group that seeks to limit billboards. "Bright, constantly changing signs on the sides of roads are meant to attract and keep the attention of drivers, and this study confirms that this is exactly what they do." The Federal Highway Administration allowed digital signs for the first time in 2007 after concluding they did not pose a significant danger. But a follow-up report is pending   and could be released this year. California has no law banning the billboards, and is one of 39 states that allows them. "We would need to review more research, so it's too early to call for a ban," says Jonathan Adkins, executive director of the Governors Highway Safety Association. "There is a role for digital messaging, such as conveying urgent information and other safety messages." There are more than 1,800 digital billboards nationwide, more than double the number five years ago. While no data indicate an increase in accidents due to the Bay Area signs, many drivers are opposed to them. "Monstrosities" is what Merlin Dorfman of San Jose calls them, while insurance agent David Whitlock says he has found them a major distraction. "They're much too bright at night," he says. "When the advertisement switches from a bright color to a darker one, your eyes cannot adjust fast enough, and you end up losing sight of the roadway." Officials with sign companies could not be reached for comment, but Bryan Parker, an executive vice president for... Which of the following is TRUE? A) The brightness of digital billboards is harmful to people's eyes. B) The Federal Highway Administration banned digital signs in 2013. C) There is evidence indicating an increase in accidents duo to digital billboards. D) Digital billboards are used to convey messages.
