On one hand, a film can be more effective in raising people's awareness of protecting the environment because it can visually show the consequences of environmental destruction and climate change, which can have a greater impact on the viewers' emotions and understanding. A film can use various techniques such as music, narration, and cinematography to engage the audience and make them feel the urgency of the issue.

On the other hand, a book can also be effective in raising people's awareness of protecting the environment. A book can provide in-depth information and analysis of environmental issues, and can also offer solutions to the problems. It can be more detailed and comprehensive than a film, and can be a valuable resource for those who want to learn more about the subject.

Ultimately, both mediums have their strengths and limitations, and the effectiveness depends on the audience and the message being conveyed. It is possible that some people may be more receptive to a film while others prefer a book. It is also important to consider the accessibility and reach of each medium. A film may be more accessible to a wider audience through theaters or online platforms, while a book may require a certain level of literacy and access to resources.

Overall, both films and books have the potential to raise awareness and promote action towards protecting the environment. It is essential to use various forms of media to reach different audiences and make a significant impact.
