“民以食为天”,饮食是人类赖以生存和发展的首要物质条件,也是社会进步的基础,因而饮食文化作为以饮食为载体而产生和发展起来的文化现象,在人类全部物质文化中,处于最重要的地位。任何文化都要依托于一定的环境,饮食文化也不例外。饮食文化在受环境影响和制约的同时,也要对环境产生反馈作用,尤其是饮食文化中的糟粕引发了种种环境问题,而这些环境问题的最终受害者无疑是人类自身。随着时代的进步,人类需要重新审视自身的饮食文化,并从饮食文化这一视角来开展环境教育,以协调人与环境的关系。 一、饮食文化对环境的负面效应 中国博大精深的饮食文化一直令国人为之骄傲和自豪,但我们也应深 相似文献

去年8月,一条百字新闻在《新疆军垦报》上刊出后,迅速在天山南北引起轰动:有人在号称“死亡之海”的塔克拉玛干沙漠里,竟发现有国家保护动物白天鹅。塔克拉玛干沙漠地处塔里木盆地中央,东西长1000多公里,南北宽400多公里,面积相当于3个浙江省。在世界最著名的流动沙漠中,塔克拉玛干仅次于非洲大陆的撤哈拉大沙漠。这里是人们谈虎色变的不毛之地,天上无飞鸟,地上无寸绿。维吾尔人称它“进去出不来”,西方人叫它“死亡之海”。晋代高僧法显路过这里时。在《佛国记》里描述:沙河中多有恶鬼热风,遇者皆死,无一余者。据新疆军区某部班长孙谦仪介绍,去年秋天,他带领5名战士到大漠边上执行任务,返回途中忽然发现4只长着长颈、羽毛雪白的大 相似文献

黄秋耘上个月刚刚去世。人们不会忘记他所透支给大众的爱。他在最后的日子里竟然读了雪波的这部长篇,而且写下“颇有意思”,“使我掉下泪来了”的评语。黄秋耘说过:“我自己是个‘罗兰党’。”他一生从不讳言他的人道主义立场,“也许人到黄昏,更容易伤于哀乐吧。”我相信秋耘。《大漠狼孩》是一部写实的大寓言。写非人之人性或写善性之人性,新作不在少数。前苏联的长篇《白比姆黑耳朵》,动物片《狐狸的故事》等。王蒙的《杂色》,困乏的老马竟然开口说话:“让我跑一次吧!”宗璞的《核桃树下的悲剧》听到核桃村的哀鸣。张承志的黑骏马那眷眷之情总是在“无言地述说着什么”。乌热尔图的《一个猎人的恳求》和《七岔犄角的公鹿》。狗通人性,公鹿像大丈夫一般爱子。前不久在《北京晚报》上读到一篇美国人写的《狼故事》.写一个狼孩带着 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 相似文献

The increase in the number of tourists visiting a coast is desired by most of the countries for economic reasons. However, this increase in tourism may cause pollution of the sea. This can be only avoided by proper planning and by predicting the carrying capacity of the coast in terms of sea pollution. This is especially important for developing countries where part of the wastewater is discharged without any treatment into the sea.In the present study the beaches were classified according to their use — and consequently the amount of waste discharged into the sea — into four groups: (1) coasts that are used only for swimming and recreational purposes; (2) coasts used simultaneously for dwelling, swimming, and recreational purposes; (3) coasts along which only dwellings exist; and (4) natural and man-made harbors, i.e., coasts used as shelters. During the survey,40,320 observations were made between December 1985 and February 1988 to determine the effect of the number of tourists on seawater quality. The results obtained were analyzed by a multilinear regression program to obtain an empirical equation giving the extent of the sea pollution in terms of coliform concentration as a function of population density and some other environmental factors.The equations derived in this study enable the determination of the carrying capacity of a beach in terms of pollution as well as the expected degree of pollution corresponding to a given population density. Furthermore, it allows the prediction of the extra carrying capacity that can be obtained by improving the waste-disposal conditions. 相似文献
