To instruct.CRoughly half of Americans drink coffee every day. Rarely do they think much about the people half a world away who picked the beans. “The work of picking coffee is demanding, literally backbreaking work,” explains Janet Jarman, an American photographer who’s been documenting coffee workers around the world for almost two decades.On a typical coffee plantation in Mexico, Nicaragua, and many of the other countries where the crop is produced, the work begins before sunrise. Coffee pickers rise early to traverse(穿刺)steep hillsides where the coffee plants grow and then spend up to 10 hours collecting the red cherries from which beans will later be extracted. Pickers can also encounter serious health dangers: for instance, the mosquitoes in these areas have been known to carry diseases like dengue or even Zika.Coffee labor is often performed by migrants who travel from poorer parts of the, continent to find work on the plantations. The harvesting period lasts from roughly November to February, so workers either leave their homes for many months at a time or take their entire families with them. They eat and sleep on the estates(私有土地), oftentimes in dirty conditions.One plantation can employ over 600 workers at the height of harvest, though sizes vary. Workers’ ages, too, span a very wide range: Jarman met men in their 60s doing the taxing work of collecting the fruit and carrying it back painfully. It also wasn’t unmon to see parents and children doing the same work together.Despite all the struggles these workers face, a lot of people took great pride in their craft, particularly those who ran and worked smaller farms. A lot of these people consider growing coffee to be a true art.28.

Things made of plastic can be very strong and last a long time. They also do well in extreme heat and cold. Plastic is also much lighter than metal and can easily be formed into different shapes. This makes the material ideal for countless uses across many different industries.But the widespread use of plastics across the world is causing major problems for the environment. Plastic material is flooding landfills and causing severe damage in the world’s oceans. Plastics can take hundreds of years to break down on their own. It has been estimated that even the most reusable kinds of plastic can only be recycled at a rate of 20 to 30 percent. Even when recycling is possible, the process is costly, can use a lot of energy and, in many cases, produces poorquality materials.But a team of researchers working at the U. S. Department of Energy says it has created a kind of plastic that could lead to products that are 100 percent recyclable. The team recently reported the discovery in a study in the journal Nature Chemistry. Tne researchers say the new material is a plastic polymer(聚合物)called polydiketoenamine, or PDK. The team reports that the material can be broken down in parts at the molecular(分子)level. It can then be built up again to form plastics of different shapes, textures, colors and more. The researchers say this process can be repeated over and over again—without the plastic material losing any performance or quality.Brett Helms is a scientist who worked on the study. He said, “Then we would be able to more effectively div
