The microplastics(微型塑料) problem in the oceans has made its way to sea turtles in a big way. A new study has found microplastics in the stomach of every single turtle they tested—a total of 102 sea turtles.
The researchers tested more than 100 sea turtles from all seven kinds and three different oceans, and they were looking for man-made things less than 5 mm long. The most things the team found were fibers, which most likely came from clothing and fishing equipment.
“The influence of these particles on turtles is unknown,” said Emily Duncan. “Their small size means they can pass through the stomach without causing a problem, as is frequently reported with larger plastic pieces.”
The researchers found more than 800 man-made particles in the turtles, but since they only tested part of the stomach, they believe the total number of particles could be 20 times higher. They don’t know how the turtles take in the particles, but they think they are from polluted seawater and polluted plants.
Professor Brendan Godley said that eating microplastics isn’t the biggest problem to sea turtles at the moment, but it is a clear sign that we need to do a better job watching global waste.
This turtle study shows that we need to reduce the amount of plastic waste, so we can keep clean and healthy oceans for future people.

【推荐1】NEW YORK (Reuters) — Global warming has cut about $5 billion worth of value from the world’s most commonly grown grains over 20 years, according to a new study.
Warming temperatures from 1981 to 2002 cut the combined production of wheat, corn and other crops by 40 million tons per year. “Contrary to what most people think, this study shows that warming over the past two decades has already affected global food supply. The effect is not a faraway thing,” said Christopher Field, a co-author on the study, the first to estimate how much global food production has already been affected by climate change.
Not every scientist agrees that agriculture is suffering from warmer temperatures. A UN report said warming is expected to turn the planet a bit greener by encouraging plant growth, but crops and forests may wilt beyond mid-century if temperatures keep rising.
Average global production for several of the crops suffered from warmer temperatures, with production dropping by about 3-5% for every 1°F increase, the study said. Average global temperatures increased by about 0.7°F during the study period, with even larger changes in several regions.
“If the past is an indication, agriculture will also suffer going forward,” Field said. “We expect future warming to continue to be a drag on grain production, like driving with the parking brake engaged.” The study said the cereal crops hit by global warming account for 55% of non-meat categories consumed by humans and they also contribute more than 70% of the world’s animal feed.
“Farmers can adapt to warmer temperatures by changing crop planting times, the varieties they grow, or the locations used for each crop,” Field said. “In the past farmers have been very adaptable to environmental challenges, but adaptation to warming can take years.”

【推荐2】Careers in zoology are extremely varied and unique, and can provide incredible learning and work opportunities for anyone devoted to animal studies and welfare. Zoology, or the study of animals, is a wide field with many specialties, including research, conservation, veterinary (兽医的) medicine, and the care of animals. For people with a love of animals and some training, dreams of careers in zoology may come true.
Some careers in zoology focus on research and scientific studies. These careers may allow those with a good theoretical science background to develop and run studies that improve human understanding of the animal world. Research in zoology can help create safer and more effective products for animals or can teach humans more about animal behavior in order to aid in conservation, breeding programs, and habitat preservation.
Careers in zoology that focus on conservation attach great importance to the continued survival and increased protection of animal species. Conservationists may work with political groups or governments to help make laws to protect and preserve animals, or may work in the field gathering information on potential threats to the health of global ecosystems. Some conservationists work in educational fields, trying to improve human efforts to save animals from extinction.
Animals are subject to illness and injury, and some careers in zoology help to create a safe, stable animal population. Veterinary medicine is an important specialty field, and may take several years of intensive training to qualify as a certified veterinarian. While many veterinarians focus on the small-animal practice of domestic pets, vets in rural areas often work with large farm animals and more adventurous veterinarians may work with exotic species in zoos and wildlife preserves. .
Humans love to observe animals, and modern-day zoos and wildlife preserves help meet that interest while providing facilities to assist with conservation programs. Zoology careers in zoos can range from overseeing breeding programs, to creating the proper diet for a deer, to cleaning the tiger’s cage. Many volunteer and entry-level jobs are available for people that love animals.
1. What is the purpose of researching on animals in zoology?| A．To help governments make laws. |

【推荐1】Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills (风车) began to be used in ancient Iran back in the 7th century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote (偏远的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available (可利用的) to people in almost all areas of the United States, windmills were seldom used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

【推荐2】In a joint effort to tackle the climate crisis, humans are turning to offshore wind farms (OWFs) as a source of renewable energy. OWFs are, quite literally, one of the biggest forms of renewable energy. The world’s largest OWF covers an area of 462 square kilometers, with each turbine (涡轮) standing 200 meters above the sea. It has the capacity to power over 1.4 million homes. But what impact do the towering turbines have on life in the waters below and the skies above?
It’s thought that OWFs could affect marine (海洋的) life in a number of ways, from noise disturbing the behaviors of fish and whales to changes in the diversity of species in the area. Seabirds that live in the North and Baltic Seas — where a vast majority of OWFs are placed — are also thought to be endangered by turbines. A report from Bird Life International found that twelve North and Baltic seabird species were at high risk of crashing with farms and seven at high risk of being displaced by their construction.
Not all impacts are negative though — some research has suggested that OWFs have the potential for environmental benefits too. A study following the movement of gray seals in the North Sea found that they were frequent visitors to two OWFs, searching between turbines for food. The researchers suggested that farms be acting like artificial reefs, representing a new and concentrated source of food. In areas where marine life has become less dense, it could allow life to flourish (繁荣) once again.
Even so, researchers explained that it’s difficult to predict the full extent of the potential environmental outcomes from these unexpected artificial reefs: “Only a small proportion of our study seals used wind farms or pipelines,” study author Deborah Russell told The Guardian at the time.
To avoid replacing one problem by creating a new one, it seems that researchers and developers will have to continue working hand in hand to ensure OWFs and marine life can successfully live side by side.

【推荐3】Pollution’s disastrous effects on the environment have become more obvious in recent years, leading to a movement to promote energy efficiency, less reliance on fossil fuels and a reduction in air and water pollution. Most scientists agree that such changes are necessary to protect our environment from further harm.
The construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. In the United States, building and development account for 39 percent of the country’s total energy use, 12 percent of total water consumption, 68 percent of total electricity consumption and 38 percent of carbon dioxide emissions, according to the Environment Protection Agency.
Green buildings use less energy, water, create less waste and are healthier to live, work and go to school in than standard buildings. Builders of green buildings use techniques that use resources more efficiently during the entire building cycle — construction, restoration, operation, maintenance (维护) and demolition (拆毁) — than those who construct more regular buildings.
The environmental benefits of building green include the protection of ecosystems and biodiversity, improved air and water quality, less waste flowing into streams and the conservation of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live there.
The process of building green includes technical and artistic planning with nature conservation in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials long distances.
Careful site selection is important to minimize (最小化) human impact on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool breezes (微风) and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small.
Green roofs are another feature of green houses that reduce energy use and cost. These roofs are partially or completely covered with plants, which helps to keep heating and cooling costs low, prevent water running off and deal with pollutants.
Other features of green buildings often include energy and water conservation, recycling and waste reduction. In addition, renewable energy sources such as solar power, hydropower (水能) and wind power are used for heat and electricity, which greatly reduces costs and decreases the impact on the environment.

【推荐1】In the rush of day-to-day life, we don’t always have the time to slow down and move at our own speed. Even on vacation, we always try to visit, do and taste as many things as possible in a new place or many places.
“I’ve heard countless times how tired people are when they come back from their vacation and feel like they ‘need a vacation from their vacation,’ and that’s because many times we pack so much into a very short time,” said travel blogger Esther Susag. “We want to see everything, do everything, and not waste a minute.
There is, however, another method that many experienced travelers suggest: slow travel. But what exactly is slow travel, and how do you take full advantage of this kind of trip? Below ,travel experts break it down.
As the name suggests, slow travel generally needs travelers to slow down and enjoy each moment, rather than rushing to check off the list items. “Slow travel may mean different things to different travelers, but I define (定义) it as staying in one place for longer and going deeper into the local culture,” said Paul Jacobs, general manager and vice president of Kayak North America. “It’s taking the time to make real connections with locals instead of packing a schedule full of tours.”
For travel expert and author La Carmina, slow travel allows people to stop and smell the roses-quite directly. “It’s about being fully present in the moment and experiencing the sights, sounds and sensations (感觉) around you completely “letting the experience develop at its own speed and without expectations,” she said. “To me, slow travel doesn’t have a strict definition or certain things to do, but rather focuses on the feeling of being a visitor to a place.”
Slow travel is becoming more and more popular now, because it can do good to us in many ways.

【推荐1】Albert Einstein has a great effect on science and history. An American university president once said that Einstein had made a new outlook—a new view of the universe. It may be sometime before the average mind understands fully the identity of time and space and so on, but even ordinary men now understand that the universe is something larger than ever thought before.
By 1914 young Einstein had been worldfamous. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties, little teaching and unlimited chances for study, but soon his peace and quiet life were broken by World War I.
Einstein hated fighting and killing. The great suffering of the war affected him deeply, and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work. In the years following World War I, honours were increasingly put on him. He became head of the Kaiser Whihem Institute of Theoretical Physics. But he himself refused the effort to put him in a position far above other people. He was well known for his humble manners. He often said that his success would certainly have been achieved by others if he had never lived. In 1921 he won the Nobel Prize, and he was honoured in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.

【推荐2】An elephant, who accidentally fell into a dry, 25-foot deep well in Northeast India, lived to see another day thanks to the quick-thinking rescuers' scientific knowledge. The chain of events unfolded early in the morning on Tuesday, January 28, 2020, when citizens of Amliya toli village, in the state of Jharkhand, awoke to the cries of the trapped animal and called the forest department for help.
When the rescuers arrived, they instantly realized that pulling out the huge animal, which seemed to be about 30 years old, was not a practical idea. Fortunately , the forest department officials had been paying attention in their science class and were well aware of the Archimedes' principle. The physics law of buoyancy(浮力)，which explains how ships stay afloat, states that when a body is partially or fully immersed in a liquid, it experiences an apparent loss in weight that is equal to the weight of the liquid displaced by the part of the body in the liquid.
In this case, that meant filling the well with enough water to displace the elephant's weight. It took the three motorized pumps over three hours to add the hundreds of gallons needed to enable the heavy animal to float up to the surface. However, it was well worth the effort. A heart-warming video shows the villagers cheering as the animal, using the makeshift ramp (斜坡)dug by the rescue team, pulls itself out of the well and walks away to safety in the nearby forest.

【推荐3】The word "barbecue" comes from the Caribbean word "barbacoa", which originally wasn't a way of cooking food, but the name of a wooden structure used by Taino Indians to smoke their food. It was recorded that the first barbecue as a diet consisted of some sort of fish, creatures from the sea obviously being plentiful in the Caribbean. Besides used for cooking, the structure of sticks could also be used as an area for sleeping, storage, and a shelter.
Spanish explorers took the word "barbacoa" back to Spain, where it appeared in print for the first time in 1526.At first,"barbacoa"still referred to the structure in which food was cooked, but later people started using it to refer to the process of cooking food in a barbacoa and the cooked food itself.
It was in A New Voyage Round the World written by William Dampier, published in 1697 that the word firstly appeared in print in English. It referred to the structure as a place for sleeping. By 1733, "barbecue began to mean asocial gathering when meat was grilled. About two decades later, in 1755, the word"barbecue"was entered into Samuel Johnson's A Dictionary of the English Language.
Today, there are different spellings as well as meanings for "barbecue". Many people use"barbeque,"BBQ", "Bar-B-Que, and other forms. The"official "spelling is generally considered to be "barbecue"with the letter"c, similar to the original. While people may debate over what should be the correct spelling or what exactly constitutes barbecue,there is one thing we all agree on: a barbecue is definitely no longer a shelter or a sleeping structure!
President George Washington himself was a big fan of barbecue. He wrote in his diary about going to a barbecue in 1769("Went in to Alexandria to a Barbecue and stayed all Night ), and hosting one in 1773("a Barbicue of my own giving at Accatinck"). Barbecue competitions have been taking place since at least 1959. The first one seemed to have taken place in Hawaii, just a few months after it became a state, but was only for men. 25 men competed for the grand prize of $10.000.
