B1. The day harmful insects or beasts won't be Evil anymore

Symbiotic relationship with organisms

Why can't humans and organisms live with mutual respect? By unraveling the past and re-examining our relationships, we might be able to start something better.

Since the hunter-gatherer era, animals have not only been targets of hunting but also partners in hunting and sources of labor in a symbiotic relationship. From this, pets as companion animals have also emerged.

The pet boom occurred due to population growth and improved living standards, leading to the recognition of pet rights as an issue. Additionally, efforts to address climate change and sustainability have intensified, making ecosystem management and conservation important challenges.

Space development has become active, with concepts of migration to Mars and research and development of closed ecosystems such as aquaponics progressing. On Earth, efforts to ensure pets are mentally and physically healthy and happy have begun.

The values of symbiotic relationships with animals have been reiterated due to the necessities of the space exploration era. As the mutual influence between space and Earth progresses, an environment where non-human animals can also live happily has been realized.

While there are animals that become companions, pests and harmful animals are despised as they cause damage to crops and harm to people. To control them, measures such as using natural predators were implemented, and animals like bears and locusts were utilized as food.

Pesticides and electric fences are used for extermination and segregation. Various approaches to pest and harmful animal management are being explored, and the control of invasive species and coexistence with animals are sometimes subjects of debate.

Astronaut Rina was on a lonely mission in the vastness of space. In the confined space of her spaceship, her only solace was a wristwatch-like wearable pet. This small device wrapped around Rina's wrist comforted her with the warm vibrations and gentle light of the microorganisms inside. While these microorganisms are a type of dangerous pathogen harmful to the body, they are safe within the watch. Due to their rarity and unique characteristics, they have come to be kept as pets. The device detects Rina's heart rate and plays soothing music when she feels stressed. Through the time spent with her pet, Rina felt the warmth of life and could experience love and connection even in the lonely cosmos.

Cockroaches were once despised by people and sadly exterminated despite their innocence. However, times have changed, and insect droppings and carcasses are now crushed and utilized as valuable fertilizer. Household insect attractant devices, which lure insects without direct visibility and convert them into fertilizer, have become common in home improvement stores as a byproduct of space development. In the past, products that exterminated and converted cockroaches into fertilizer without being seen were mainstream. Recently, however, due to the benefits cockroaches bring to humans, they have also been treated as ornamental pets. Alongside the ever-popular rhinoceros beetles, cockroaches are increasingly becoming a popular subject for elementary school summer research projects.

Large walking robots, initially used in space development, have become versatile and are now utilized in construction and forestry. The Matagi Robot, which combines the ancient wisdom of the Matagi (hunters) with robotic technology developed through space exploration, monitors and understands the behavior of animals, constantly informing humans to prevent dangerous encounters. These robots also function as substitutes for the extinct Japanese wolves, sometimes hunting bears and deer, and have recently become a stable source of meat. Lost cultures and irretrievable ecosystems are now being patched and supplemented by machines, much like prosthetic teeth or limbs, and are becoming integrated into daily life.

In the cities of the future, strange culinary cultures are emerging in the name of sustainability. The restaurant "Eco Delight" is famous for its yukhoe made from crow meat. The chef captures crows that scavenge urban waste and carefully prepares them, addressing issues related to food waste and pest bird damage, thereby contributing to their resolution. Crow meat is said to have a rich umami and unique flavor, and due to the effort required for its capture and preparation, it is traded at high prices. Alongside heron chick meat and starlings, crow meat has become popular at this restaurant.
