The book I recommend to you is "The End of Doomsday". It is a novel about the Earth entering a period of death, with earthquakes and tsunamis happening every day. All humans are unable to survive and are forced to migrate to the interstellar space to find a suitable place for human survival. I hope you like this fairy's recommendation. Muah ~😗
A really well - known one is 'Watership Down'. It's about a group of rabbits finding a new home. Along the way, it shows how nature works, the importance of habitats and how different species interact, which is very relevant to the concept of a 'green planet earth'.
Once upon a time on Planet Earth, there were lush forests filled with all kinds of animals. The trees were tall and provided homes for birds and squirrels. In the oceans, beautiful corals swayed gently. But then humans started to cut down the forests for land and resources. Many animals lost their homes. However, some kind - hearted people realized this and began to plant trees and protect the environment. Now, Planet Earth is slowly getting better, with more and more areas being conserved for the future.
In some fanfiction, the powerful magic in 'Game of Thrones' could be used to protect the endangered species on 'Planet Earth'. For instance, a wizard from Westeros could use spells to safeguard the pandas in China or the polar bears in the Arctic. It would be a unique way to combine the two universes.
It might be about the end of the world scenarios that are based on scientific facts. Maybe it's about how the polar ice caps are melting at an alarming rate due to global warming, which is a true phenomenon. This could lead to rising sea levels and the flooding of coastal areas, ultimately threatening the existence of life on Earth as we know it. Or perhaps it's about the depletion of natural resources and how that could lead to the collapse of ecosystems and civilizations.
Perhaps its unique point is the combination of a single man's story with scientific aspects of Planet Earth. It could be that the way it presents the man's experiences in the context of Earth's scientific phenomena makes it stand out.
Perhaps in the fanfiction, the technology from Star Wars is used to explore the deepest parts of Planet Earth. For example, using starships to reach unexplored caves or the ocean floor.
The theme of good vs. evil can be incorporated. For example, environmental protectors on Earth could be the 'good guys' and polluters or those who harm the planet could be the 'evil'. Just like in Star Wars, the good side fights to preserve balance.
I'm not sure specifically as I haven't read this particular graphic novel. But it might be about John Muir's view on the Earth, the planet in the context of the universe. Maybe it shows his environmental ideas and how they relate to the bigger picture of the cosmos.
