人们一度认为,约占地球70%表面的海洋具有无限的自洁能力,人类的污染不会触及海洋。然而,现代科学研究表明,海洋污染越来越严重,甚至波及到深海区域。为了改善海洋生态环境,科学家们致力于开发海洋环保技术。最近,国外杂志评选出近年来有利于改善海洋环境的五种新技术。 It was once thought that the ocean, which accounts for about 70% of the Earth’s surface, has infinite self-cleaning ability and human pollution will not touch the oceans. However, modern scientific research shows that marine pollution is getting worse and even reaches the deep-sea area. In order to improve the marine environment, scientists are devoted to the development of marine environmental technologies. Recently, foreign magazines selected five new technologies that have helped to improve the marine environment in recent years.
