人类生存离不开自身的周围环境,环境养育了人类。人类为了让生活的环境变得更好,在不断地改造环境,扩大对环境资源的利用。这种人为的改造和利用,可使环境越来越适合人类生存的需要,但随着世界人口不断增长、生产不断发展、人民生活水平日益提高,对环境的破坏也日益严重,环保问题已经变成当今国际社会面临的严重问题,环境保护已引起了世界各国的高度重视。目前全世界比较关注的一些环境问题,比如:大气污染、臭氧层空洞、温室效应、酸雨、海洋污染、淡水缺乏、土地沙漠化、植被减少、生物种群灭绝、有毒化学品、环境公害等方面,绝大多数问题都与化学有关。因此,作为化学教师,我们有必要尽到自己的责任,不失时机地寓环保教育于化学教学之中,让学生学习一些环境保护知识,多了解这些污染物的产生、性质及危害,以便主动地去预防或减少这些污染物对环境及自身的毒害。加强对学生环境知识的教育,可以增强学生的环保意识。
Human beings can not live without their own surroundings. The environment has nurtured human beings. In order to make the living environment better, human beings are constantly transforming the environment and expanding the use of environmental resources. This kind of man-made transformation and utilization will make the environment more and more suitable for the needs of human survival. However, as the world’s population continues to grow, production continues to develop, and people’s living standards have increased, the damage to the environment has become increasingly serious and environmental issues have changed. As a serious problem faced by the international community today, environmental protection has attracted the attention of all countries in the world. Some of the environmental issues that the world is currently concerned about, such as: air pollution, ozone hole, greenhouse effect, acid rain, marine pollution, lack of fresh water, desertification of land, reduction of vegetation, extinction of biological populations, toxic chemicals, environmental pollution, etc. Most problems are related to chemistry. Therefore, as chemistry teachers, it is necessary for us to fulfill our responsibility and lose no time in integrating environmental education into chemistry teaching. Students should learn some environmental protection knowledge and learn more about the production, nature and harm of these pollutants so that they can take the initiative to go Prevent or reduce the poisoning of these pollutants to the environment and itself. Strengthening the education of students’ environmental knowledge can enhance students’ awareness of environmental protection.
