Before enrolling the pregnant women in the intervention group, the informed consent form, the personal information form, the climate change awareness scale for pregnant women and the climate change hope scale (pre-test) will be completed. The researcher will then give a 30-minute training presentation on the climate crisis to the pregnant women individually in the conference room on the third floor of the maternity hospital. Two weeks after the training, the worker will open a meeting session via Microsoft Teams or Google Meet, and a short animated film will be watched on this platform as a reminder. Four weeks after the viewing of the short animation film, another meeting session will be set up via Microsoft Teams or Google Meet and the link to the survey form will be shared online and the final evaluations (post-test - questions on climate change, climate change awareness scale and hope scale for preventing climate change) will be carried out.

No application will be made to the pregnant women in the control group, and the informed consent form, personal information form, Climate Change Pregnancy Awareness Scale and Climate Change Prevention Hope Scale (pre-test) will be completed at the first interview. During this time, a sign will be hung on the door to prevent anyone from entering or leaving the room. Six weeks after the first interview, the link to the survey form (Questions about Climate Change, Climate Change Pregnant Awareness Scale and Climate Change Prevention Hope Scale) will be shared with the pregnant women via Microsoft Teams or Google Meet and their final evaluation (post-test) will be conducted. A video interview will be conducted with the control group in a Microsoft Teams or Google Meet meeting to ensure that real people completed the form. At the end of the study, an educational booklet and a short animated film on climate change will be sent online.

For the short animated film, a scenario will be created that describes climate change, risk factors that threaten human health as a result of climate change, adverse health effects of climate change, adverse effects on maternal and foetal health, precautions to be taken to protect against and adapt to the adverse effects of climate change. In the short animation film, visual materials will be created that show the adverse effects of climate change by using developing technology. The created scenario will be prepared as a two-dimensional (2D) animation film with the support of Selçuk University SERATEM (Selçuk University Radio and Television Application Center). All lines, colours, decorations and characters used in the creation phase of the short animation film will be determined by the researchers. Once the drawing and animation phases are complete, the voice-over actors will be selected after a further review. The short animated film should be about 2-3 minutes long.

The personal information form is a questionnaire developed by the researchers based on the literature. The survey includes 13 questions on the introductory socio-demographic characteristics (age, education, etc.) of women and their husbands, 16 questions on the obstetric characteristics of women (gestational week, number of pregnancies, etc.), and 18 questions on climate change (Ha et al. 2018, Kısrık and Avcıbay Vurgeç 2022, Leung et al. 2023).

The Climate Change Pregnant Awareness Scale is a 21-item scale developed by Kısrık and Avcıbay Vurgeç (2022) to assess pregnant women's awareness of the effects of climate change on maternal-fetal health. Each of the scale items is a 5-point Likert-type item as "1-I strongly disagree, 2-I partially disagree, 3-I am undecided, 4-I slightly agree, 5-I strongly agree". There is no reverse item in the scale. It consists of 3 subscales: General (items 1, 2, 3, 4, 7 and 8), Fetal (items 5, 6, 11, 12, 13, 14 and 15 and 16) and Maternal (items 9, 10, 17, 18, 19, 20 and 21). The score obtained for each sub-dimension indicates awareness of that sub-dimension. The minimum score for the total scale is 21 and the maximum is 105. As the total score increases, women's awareness of climate change increases. The overall Cronbach's alpha coefficient of the scale is 0.94.

In a global crisis such as climate change, individuals' hopes can increase their active participation in finding solutions to mitigate and adapt to climate change (Sangervo et al. 2022). The Hope for Prevention of Climate Change Scale (HOC) was developed by Li and Monreo (2018) to measure individuals' hope for preventing and combating climate change (Li and Monreo 2018). Li and Monreo (2018); emphasise that the scale can be used by researchers who want to use a quantitative approach to investigate climate change hopes, or to test the effectiveness of climate change education programmes to increase individuals' climate action. The use of the scale is particularly important in awareness-raising and education programmes in terms of measuring not only individuals' knowledge about climate change, but also their motivation and belief that they can turn this knowledge into action (Li and Monroe 2018).
