Less meat and dairy in our diets could help reduce agricultural greenhouse gases by as much as 80% by 2055, according to a recent study by the Potsdam Institute for Climate Impact Research (PIK). The researchers created global land-use model to project likely outcomes given different scenarios involving consumer dietary trends and changes in agriculture production methods. The models take into consideration population growth, the world economy, and other factors.The researchers found that, if meat and dairy consumption patterns remain constant of increase, the associated global agricultural omissions will increase significantly. On the other hand, a 25% reduction over the next 40 years would help bring levels to where they were around 1995.Methane and nitrous oxide in particular could be reduced if less meat and dairy is produced and consumed. These gases are caused largely by livestock waste and synthetic fertilizers. Around two-thirds of nitrous-oxide emissions come from agriculture—and most of that as a result of either raising animals or producing the feed used to raise them. Consumers'food choices, combined with what one PIK researcher terms “technical mitigation options on the producers side” could make an enormous impact on these emissions.While not nearly as much methane or nitrous oxide is released into the atmosphere as carbon dioxide, both are significantly more potent and they form substantial pieces of the greenhouse gas pie. Both of these gases trap heat and radiation in the atmosphere much more effectively than does carbon dioxide. The U.S. Environmental Protection Agency cites methane as being "21 times more effective at trapping heat in the atmosphere than carbon dioxide over a 100-year time period. " Nitrous oxide is more than 300 times more effective than CO2.While the PIK study doesn’t detail exactly which consumer choices and eating habits can help reverse the trend, it seems clear that less is more when it comes to consuming meat and dairy products.1.The current PIK study（ ）.2.As the PIK results imply, it is possible（ ）.3.Simply put, to produce and consume less meat and dairy is to（ ）.4.The greenhouse gas pie tells us（ ）.5.

On June 26, 2000, two scientific teams announce at the White House that they had deciphered virtually the entire human genome, a prodigious feat that involved determining the exact sequence of chemical units in human genetic material. An enthusiastic President Clinton predicted a revolution in “the diagnosis, prevention and treatment of most, if not all, human diseases”.Now, 10 years later, a sobering realization has set in. Decoding the genome has led to stunning advances in scientific knowledge and DNA-processing technologies but it has done relatively little to improve medical treatments or human health.To be fair, many scientists at the time were warning that it would be a long, slow slog to reap clinical benefits.And there have been some important advances, such as powerful new drugs for a few cancers and genetic tests that can predict whether people with breast cancer need chemotherapy. But the original hope that close study of the genome would identify mutations or variants that cause diseases like cancer, Alzheimer’ s and heart ailments—and generate treatments for them—has given way to realization that the causes of most diseases are enormously complex and not easily traced to a simple mutation or two.In the long run, it seems likely that the genomic revolution will pay off. But no one can be sure. Even if the genetic roots of some major diseases are identified, there is no guarantee that treatments can be found. The task facing science and industry in the coming decades is at least as challenging as the original deciphering of the human genome.1.Back in the year 2000, what was exciting about the deciphered genome?2.Clinically, according to the passage, the prophecy ten years later （ ）.3.From our disappointment we have to realize that （ ）.4.It can be concluded from the passage that （ ）.5.The writer's tone in the passage is （ ）.
