A wondrous and beautiful world protected by insects
Take a look at the countless small beings that support the Earth!

Edward Wilson, considered one of the greatest biologists, said, “It is the little insects that make the world go round.”
But how many people truly value insects? This book completely overturns the misconception that insects are disgusting and harmful to humans.
Insects eat up waste, enrich the soil, and provide moisture to plants.
There are countless invisible bugs that keep the water clean.
Technologies like nanofibers and computer algorithms are also inspired by bugs.
Could there be another being so beautiful, so intelligent, and so beneficial?

Yet, we covered their land with concrete and poured all kinds of chemicals into the land and sea.
Insects are becoming extinct at a rapid rate.
Have you ever imagined a world without bugs? Without them, flowers and plants would be unable to survive, and the animals that prey on them would also disappear.
Our tables will be empty, and our streets will be littered with garbage.
The entire Earth's ecosystem will be shaken.
In a world without bugs, humans cannot survive.


How can we bring back extinct insects? The author, an environmental activist and entomologist with 30 years of experience, uses abundant examples and solid evidence to unravel the factors that have contributed to the extinction of invertebrates and the solutions we can offer.
The key is to give bugs a place to call home.
Even small actions like leaving weeds and wildflowers on the roadside or growing plants on your balcony can provide shelter and food for bugs.
If you love nature, open this book.
Not only will you gain insights into the amazing world of bugs, you'll also gain useful tips for protecting these precious creatures that sustain nature.

Even a small number or a very small percentage of bugs can disappear, leaving an area devastated.
Insects are at the bottom of the food chain.
So when bugs disappear, the species that prey on them also disappear.
Large animals that people love and that therefore hold significant significance to human identity and culture, such as birds, bats, some mammals, fish, reptiles, and amphibians, will also disappear.
We will be hit by a tidal wave of shocks that we cannot even imagine, transforming entire ecosystems and landscapes.

If bugs disappear, the world's landscape will also change.
The beautiful meadows buzzing with bees will become a distant memory, and only images will allow us to see the world once so vibrant and full of colors, sounds, and scents.
As we walk down the street, flowers and trees will no longer greet us, nor will they provide cool shade on hot days.
Instead, we may find ourselves walking through ever-growing mounds of garbage as the invertebrates that scavenge and break down waste and waste disappear.

Invertebrates are very numerous and diverse and live almost everywhere on Earth.
They originated as ocean sponges and have survived and evolved on Earth for over 650 million years.
This is an incredibly long time considering that humans have only appeared on Earth for a mere 200,000 years.
Invertebrates, after a long period of adaptation, have become able to live almost anywhere on Earth.
The form and function of invertebrates have evolved in close relationship with the biological, chemical, and physical world that surrounds them.
Earthworms, perfectly adapted to life underground, can use their smooth bodies to efficiently dig the ground and move quickly by pushing the soil with the short, stiff hairs (setae) on each body segment.
The long, tube-like tongue of the hawk moth can reach deep into flowers that other insects cannot.

Rehabilitation is about helping these small but important creatures thrive in virtually every environment on Earth, whether pristine or otherwise.
To do this, we must preserve insect populations in areas where they are already abundant to prevent further decline, and work to restore populations in areas where insect populations are scarce.
We also need to allow bugs back into our daily lives, homes and workplaces.

As far as we know, ants are the animals that form the largest cooperative society.
Ants can form enormous 'super-colonies' that can stretch for hundreds of miles.
One supercolony of Argentine ants discovered in southern Europe is estimated to stretch across approximately 6,000 km and contain 33 populations of millions of nests and billions of workers.
Moreover, scientists have observed that Argentine ants from different colonies do not show aggression when kept together, suggesting that supercolonies of Argentine ants may have spread across the continent.
It truly is an amazing creature.

The great thing about river rafting is that anyone, anywhere can participate.
You can start by creating a small green space to attract bees or moths, or by changing your attitude and mindset toward bugs.
From a Costa Rican city that recognized bees as citizens to the remarkable transformation of 3,000 London gardens into spaces for nature,
Anything is possible, and it is actually happening right now.

Most people will be able to find even a small amount of greenery near their homes.
It could be a flowerpot on a windowsill, a small garden the size of a palm, a narrow patch of grass by the roadside, or if you're lucky, a large park or suburban area nearby.
For city dwellers without gardens, going to parks or green spaces is a way to enjoy nature.
These places are also very important to insects and are ideal locations for small regurgitation events.
These spaces are invaluable places where citizens can relax and enjoy well-being, and are also essential for protecting wildlife.
No matter how small, green space is likely to be the most suitable place for invertebrates to live.
Green spaces in urban areas provide habitats for invertebrates to find food, build homes, breed, and migrate to new habitats, so more of these spaces are needed to prevent invertebrate extinction.

You can create habitats that bugs love in your home and garden.
For example, you can create a "bug hotel" by placing bricks with lots of holes in them on top of a wall or between walls, or by placing old, hollow bamboo sticks.
You can also purchase ready-made products from wildlife organizations or flower gardens.
Growing ivy can provide excellent winter food for many pollinators during the bleak winter months when everything is gone.
Old logs can make a haven for beetles, and if you dig a hole in the ground and bury a few old logs, stag beetles will love it.
It may take a few years, but if you're lucky, you might see stag beetle larvae grow plump underneath and emerge as majestic stag beetles.

It is not easy to escape the pesticide cycle because continued use of pesticides causes resistance to develop in the target species.
When pesticides no longer work because pests or weeds develop resistance, people work hard to develop more powerful pesticides.
This vicious cycle continues.
This is a problem that can also have serious implications for public health.
In fact, mosquitoes, the vectors of malaria, are becoming increasingly resistant to insecticides used primarily in Africa.
Farming practices that rely heavily on pesticides are also creating pests and weeds that are resistant to conventional pesticides.
Nature is evolving to resist pesticides, and one day it may become completely uncontrollable.
If we don't change the way we produce food and fiber, we will face food inequality and serious food shortages in the future.

As you rewild your surroundings, you will witness the mystical nature.
As we go outside and walk down the street, more creatures will come up to us and say hello.
The new green space, rich in bugs, flowers, plants and fertile soil, will attract not only bugs but also birds and other animals.
The world where bugs return soothes all our senses.
Imagine the fragrance of flowering plants, the rich colors, and the sounds of life filling the city and its suburbs.
From a small potted plant on a windowsill to a large park, insects will return, attracted to the abundance of plants everywhere.
As you walk along a wildflower-lined path, you will one day realize that the fields are not just one color, but are filled with a multitude of shades of green and colorful butterflies and flowers.
