1. Every two weeks, the time period after which many people collect a paycheck, a language dies.
So concerning is the potential for language loss that the National Science Foundation launched the Documenting Endangered Languages program to advance knowledge related to endangered human languages. The launch of the program is even more urgent given the fact that about half of all current languages being ud in the world have been classified in varying degrees of endangerment.
At the University of Arizona, which is an important site for language prervation, a number of rearchers are involved in activities meant to document endangered and lost languages. Others are working to help prerve languages classified as "moribund", meaning that no children are learning their native languages as their first languages in their own homes.
A number of UA programs—some of them decades old—are dedicated to language prervation. Most recently, Christian Ruvalcaba, a graduate student, launched "The Language Capital Project" and created maps for corresponding website to help non-national language speakers to find and connect with one another.
"Languages allow people to create an identity for themlves and as community members," said Elizabeth Kickham, a visiting professor in the UA Department of Linguistics. "Language is so cloly tied to culture: it not only reflects cultural practices, it is also influenced by them. Language and culture influence each other, so it's difficult to parate them. You can, but you will lo something when you do."
"One of the advantages of studying at the University of Arizona is the wealth of linguistic diversity to be found among the student population," said Kickham, who involved her students in language prervation training this mester.

meone speaking a language they needn't feel that the person doesn't know how to speak English but rather that person has a wealth of resources."

2. A new study published in the journal Nature Communications has concluded that a 100 percent change to organic(有机的) food production in England and Wales would actually lead to a great increa in greenhou gas emissions. In turn, this would contribute to further climate change.
Although organic farming directly pours out fewer emissions than conventional farming—around 20 percent lower for crops and 4 percent for farm animals—it produces notably less food. As to this study's findings, total organic agriculture in England and Wales would produce 40 percent less food. With less food in the market, the countries would need to increa food imports, which would produce more global greenhou gas emissions.
个人思想政治总结 Organic farming also increas the amount of absorbing carbon, a process where carbon dioxide (CO2) is "absorbed" out of the atmosphere and captured by plants and stored in the soil. However, even a total change to organic farming would only be equal to a tiny part of the higher emissions from overas land u.
"We predict a drop in total food production of 40 percent under a fully organic farming process, compared to conventional farming, if we keep to the same national diet," Dr. Adrian Williams, lead author and reader in Agni-Environmental Systems at Cranfield University, said in a statement. "This results from lower crop quantity, becau output is limited by a lower supply of nitrogen, which is mainly from other crops or solid waste from cattle on the grassland."
Nevertheless, it is important to note that organic farming still holds some uful benefits for the environment, such as reducing exposure to chemicals and improving the varieties of creatures. In conclusion, the study suggests that organic farming will continue to play a key role in resolving the world's environmental problems. However, it's just one part of a much wider solution.
