In such a fictional world, ecosystems would collapse. Insects play crucial roles in decomposition and as a food source for other animals. The lack of them would have cascading effects on all life forms.
A world without insects in fiction could be a barren one. Fewer species would exist, and the balance of nature would be severely thrown off. It would likely lead to ecological disasters and changes in human survival too.
In such a novel, there'd likely be a sense of security and trust everywhere. People wouldn't have to worry about their possessions being stolen, and society might function more smoothly.
It could show a desolate and nature-dominated landscape. Maybe with wild animals thriving and plants taking over cities.
In such a manga world, there'd likely be strict rules and no room for individual expression. Maybe a totalitarian regime controlling everything.
A world without Superman comics would lack that iconic symbol of justice and strength. The genre of superhero comics might not have developed in the same way, and fans would be deprived of his adventures and the values he represents.
It would be a world lacking some unique and potentially groundbreaking stories. Many axed manga might have had great potential that was never fully realized.
Human society would become much less diverse. Insects support a vast number of species, and without them, many birds, fish, and small mammals would die out. This would mean less biodiversity in our environment, which could lead to a more monotonous and less - resilient ecosystem. In terms of our built environment, we'd likely see an increase in pests that are not insects but thrive in the absence of their natural competitors. For example, spiders that used to feed on insects might start to invade human - occupied spaces more often in search of other food sources, causing problems for people.
The setting would likely be a desolate place. Gardens would be full of wilting, unpollinated flowers. Fields would have sparse crops as they lack the help of insects for pollination and pest control. There would be an eerie silence without the buzzing of bees or the chirping of crickets at night.
In a world without insects fiction, the plot could involve a mystery. Scientists start to notice strange things happening, like certain diseases becoming more prevalent. They eventually realize it's because of the lack of insects. The story could then follow a detective - like scientist who tries to figure out how to bring insects back. They discover that a powerful corporation was behind a chemical release that wiped out the insects, and they have to fight against the corporation's attempts to keep the status quo to save the planet.
In a world without parallel worlds in manga, the imagination of the creators would be somewhat limited. There'd be fewer opportunities for mind-bending concepts and unexpected plot twists related to multiple realities.
It might be a desolate and imbalanced ecosystem. With no fish, many other species that depend on them for food or as part of the food chain could face serious survival challenges.
