1970年4月22日是第一个“世界地球日”,从那时起,人类已经意识到必须保护我们生存的环境。随着全球人口的持续增长和经济全球化,如何保护天然资源已成为全人类可持续发展的重要课题。国际天然资源保护协会的调查表明,现在世界上仅存37片“处女地”,在那里,有70%以上的动物、植物和天然资源未遭人类“毒手”。 April 22, 1970 was the first “Earth Day”. Since then, humans have realized that we must protect our living environment. With the continuous growth of the global population and economic globalization, how to protect natural resources has become an important issue for the sustainable development of all mankind. According to a survey conducted by the International Association for the Conservation of Natural Resources, there are currently only 37 “virgin lands” in the world, where more than 70% of animals, plants, and natural resources are not “hands down” by humans.
