Inspiration to act. Why is the ozone layer threatened? What are the implications of ozone depletion, and what can be done to prevent it? What contribution can developing countries make towards the phase-out of ozone depleting substances? This video provides responses to these questions, targeted at a general audience. It can also be useful for specialists involved in activities to implement the Montreal Protocol as an awareness raising tool, as part of a national information, education and communication (IEC) campaign. It is accompanied by a booklet presenting background information on the themes covered in the video in a question-and-answer format. The booklet also suggests subjects for discussion and provides references where information can be found.
