The benefit of community fridges has never been clearer. In difficult times, with pretty much all costs increasing greatly, it is reassuring to know that
2 . Meat is crucial for feeding the planet, leading scientists have said, as they warned it is not more environmentally-friendly to go vegan (素食).
Prof. Geoff Simm, Director of Global Academy Agriculture and Food Security at the University of Edinburgh, said, “I think livestock (家畜) farmers do feel they are being demonized (妖魔化).” Often the argument is made that going vegan would minimize land use, but the modelling studies that have been done demonstrate that’s not the case. We feel that while livestock production has a range of economic, social and environmental costs and benefits, the costs have perhaps been receiving far more attention recently than some of the benefits. Meat has massive social benefits. It’s an important source of dietary protein, energy, highly bioavailable micronutrients (微量营养素), even small amounts of animal-sourced food have a really important effect on the development of children, in the developing world on their cognitive and physical development and they are really important.
Prof. Mike Coffey, from Scotland’s Rural College, added, “It’s completely unnecessary to go vegan. If everybody went vegan it would be devastating for the UK environment. Animals bred for food help boost biodiversity.”
Researchers are currently attempting to breed more environmentally friendly cattle, which grow faster and eat less, which could further reduce the sector’s carbon footprint by reducing the amount of methane (甲烷) released by cows.
Prof. Coffey said that the difference in methane emissions from best and worst cattle was about 30 percent and that if all UK farmers used the most efficient animals this could reduce carbon emissions by nearly a third. But Prof. Coffey said the next stage will be trying to measure the methane given off by different breeds of cattle to find which are the lowest emitters. Prof. Coffey said that soon shoppers could be able to check meat labels to find out how much environmental impact their food has had. He added, “My expectation is that at some point in the near future there will be product labels that relates to the efficiency or carbon impact of the food.”
Professor Andrea Wilson, also of Edinburgh University, said more research was needed into the impact of veganism (绝对素食主义). She added, “We know a lot about the livestock sector because people have looked at it. We actually know very little about the vegan sector. The danger is we demonize one and jump too quickly to the other.”

4 . Some Questions About Coronavirus
How long does coronavirus last?
Every case of coronavirus is different, but experts have a general idea of how long the typical course of the illness lasts. Most people can expect to recover within two weeks after the onset of symptoms, but more severe cases could last up to six weeks — and for some, dubbed “Covid long haulers,” symptoms can linger for months.
What are the symptoms of the coronavirus?
Symptoms of the coronavirus can seem a lot like the flu. Initially, a fever, cough, and shortness of breath emerged as the three most common symptoms of COVID-19. Now, other signs such as muscle pain, fatigue, and loss of taste and smell are on the Centers for Disease Control’s (CDC) symptoms checklist.
How long does coronavirus live on surfaces?
Though the conronavirus is typically transmitted through the air via respiratory droplets (from an infected person sneezing or coughing) rather than by touching objects and materials, the virus can still remain viable on variety of surfaces, according to the CDC, though it’s not exactly clear for how long.
How is coronavirus spread?
According to the CDC, COVID-19 is spread mainly from person to person, usually through close contact (within six feet). Being near an infected person who coughs, sneezes, or talks can expose you to their respiratory droplet carrying the virus — and they can spread the virus even if they don’t have any symptoms yet. If those virus-containing particles are inhaled (吸入) or land in your eyes, nose or mouth, you could become infected.
1. How long does coronavirus stay on surfaces?| A．Two weeks. | B．Six weeks. | C．Months. | D．Unclear. |
| A．contacting close (within six feet) |
| B．being near an infected person |
| C．talking with a healthy person |
| D．inhaling some virus-containing particles |
| A．Entertainment. | B．Health. | C．Education | D．Travel. |
