The world39。s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic. Now, that may be changing. A new environmentallyfriendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland. This shopping model, called Loop, aims to replace throwaway containers with reusable ones. Loop is the idea of Terra Cycle, an Americanbased recycling pany. Its chief, Tom Szaky told the Associated Press (AP) that removing plastics from the ocean is not enough. He said the point is to get away from singleuse packages. Szaky said that Loop is the future of shopping. But it es from an idea of the past. He pared it to the milkman model of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste. Jennifer Morgan from the environmental nonprofit organization Greenpeace also joined in the discussion about Loop at Davos. She said that Greenpeace weles the aim of the Loop Alliance to move away from throwaway culture and disposability. But Morgan questioned whether panies worldwide are ready to change their business models. Loop is set to launch later this year in three eastern . states, and also in Paris, France and some of the surrounding area. Then Loop plans to expand to the . West Coast, Toronto, Canada and Britain by the end of this year or 2020.（1）What does the author intend to do in Paragraph 2?

They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, when it has collected enough information to be able to use the vast number of cells freely in the most effective way. Pure mathematics is one of the fields in which this happens, and we know that Albert Einstein made all his worldshaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them. But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a person reaches his or her peak much later in life. Besides sharpness of brain and experience, here is another thing that is very important, and that is wisdom. One can have a very quick, inventive brain and plenty of experience, but if one uses these foolishly, one harms both oneself and others. Wisdom does not always e with age ——there are plenty of foolish middleaged people about ——but the average person tends to learn wisdom as he gets older, usually by making painful of embarrassing mistakes.
