When forests disappear, migratory (遷徙的) songbirds disappear, too. In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification. Bird Friendly coffees are shadegrown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shadegrown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more plex flavor. Bird Friendly certified coffees grow under biodiverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet. Bird Friendly producers can also earn more for their crops. The wood and fruit trees on shade coffee farms provide farmers with additional ine. Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat. Buying Bird Friendly supports the Smithsonian Migratory Bird Center39。s conservation research aimed at understanding and protecting your feathered friends. You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup. Find a store or cafe near you, or better yet, have it shipped to your door when you order online.（1）What is the present situation of coffee farms?

They need to do more to prepare for the sideeffects. For the past 3,000 years, when people thought of money they thought of cash. Over the past decade, however, digital payments have taken off— tapping your plastic on a terminal or swiping a smartphone has bee normal. Now this revolution is about to turn cash into an endangered species in some rich economies. That will make the economy more efficient—but it also causes new problems that could hold back the transition(轉(zhuǎn)型). Countries are removing cash at varying speeds. In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years. America is perhaps a decade behind. Outside the rich world, cash is still king. But even there its leading role is being challenged. In China digital payments rose from 4% of all payments in 2012 to 34% in 2017. Cash is dying out because of two forces. One is demand— younger consumers want payment systems that plug easily into their digital lives. But equally important is that suppliers such as banks and tech firms (in developed markets) and teles panies (in emerging ones) are developing fast, easytouse payment technologies from which they can pull data and pocket fees. There is a high cost to running the infrastructure behind the cash economy—ATMs, vans carrying notes, tellers who accept coins. Most financial firms are keen to abandon it, or discourage oldfashioned customers with heavy fees. In the main, the prospect of a cashless economy is excellent news. Cash is inefficient. When payments dematerialise, people and shops are less open to theft. It also creates a credit hi
