我国海洋生物多样性的保护现状及法律对策   总被引:1,自引:0,他引:1  
海洋生物资源提供了人类社会重要的生存物质,有效地保护好这些资源,对促进人类社会的持续发展具有重要意义。最近几十年来,海洋生物物种灭绝的速度加快,丰富的物种多样性日趋下降,对人类的生存和生活产生一定的影响。因此,有必要结合海洋生物多样性保护的现状,分析探讨海洋生物多样性保护方面存在的问题和原因,并提出完善海洋生物多样性保护的政策和法规、建立海洋自然保护区、广泛开展海洋生物多样性保护的区域合作和国际合作等具体的法律对策。  相似文献

Rachel Carson is a famous but unknown writer. She is remembered as a pioneering heroine of the ecological movement, but even her Silent Spring is hardly read and the great books about the sea that made her name are unknown to the public. Recent biographical accounts have focused on the problems Carson faced as a woman entering the male-dominated scientific community, and the sexist reception of her books. But her real life was plainly in her writing. Although the accounts of geology in The Sea around Us and of genetics in Silent Spring are outdated, her books remain classics, not only for their lucidity and beauty, but for a vision of the impersonal processes of evolution and geological time comparable to Darwin's. This is especially true of her trilogy of books on the sea: The Sea around Us , describing the biochemistry, history and geography of the oceans and their tides, Under the SeaWind, focusing on the interdependent lives of sea-creatures, while The Edge of the Sea deals with the lives, great and microscopically small, of the intertidal world. The corresponding theme of Silent Spring is the death of nature through man's folly.  相似文献

Forensic scientists periodically check working test reagents with knowns or standards to verify that the presumptive testing reagents are working properly. Oftentimes, this is done with a neat body fluid such as blood or saliva that is dried onto a swab and kept in a freezer. The problem with this practice is that a degrading test reagent, for example acid phosphatase testing reagent, may test positive on a neat standard but miss a weak semen stain from a case.To ensure that presumptive testing reagents are working properly, a series of “weak” standards have been developed for the testing of acid phosphatase, amylase, creatinine and hemoglobin. The preparation and use of these biological standards will be discussed.  相似文献
