This paper explores the use of new media in environmental education, with an emphasis on the development of environmental literacy and the prevention of environmental alarmism. Current technological developments provide new opportunities for the dissemination of environmental information and education, but it is also important to consider the potential risks and challenges involved. The chapter contains a systematic and rigorous summary of the expert and scientific reflection on the topic over the last 10 years. From the data presented, it is possible to generate effective and objective methods to address the issue in the present, with a view to the near future. This chapter also analyzes approaches to digital technologies and media in the context of environmental education and argues for their effective use in promoting environmental literacy and a healthy relationship with environmental information. At the same time, the authors emphasize the need for critical thinking and the development of the ability to process and interpret complex environmental information in order to minimize environmental alarmism and foster a constructive commitment to protecting the planet.
