In the summers of old in Japan, countless dragonflies would fly over the rice fields.<\/p>\n

As evening came, red dragonflies filled the sky, and children grew up watching them as a normal part of their lives.<\/p>\n

Nowadays, this scene is rarely seen.<\/p>\n

It’s easy to explain the reason with simple words like “climate change” or “development,” but the real cause lies much closer to home.<\/p>\n

It’s that the circulation within the rice fields has been broken.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Dragonflies are more than just insects.
In fact, dragonflies are also a direct indicator of the condition of rice paddies.<\/p>\n

– Their larvae (nymphs) grow in water.
– They feed on microorganisms and small insects in the water.
– Adults fly into the air and return to the rice paddies.<\/p>\n

In other words, the abundance of dragonflies is evidence that:<\/p>\n

– The water is alive.
– The soil is alive.
– The insect cycle is ongoing.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In ancient rice paddies, four elements were naturally connected.<\/p>\n

\u2460 Soil<\/p>\n

Chemical fertilizers were scarce,
Fallen leaves, straw, droppings, and dead insects were returned to the soil.<\/p>\n

\u2461 Fungi<\/p>\n

Diverse fungi thrived in the soil,
Decomposing organic matter, producing nutrients, and suppressing disease.<\/p>\n

\u2462 Water<\/p>\n

Water was moving and stagnant,
Ensuring the survival of fungi and aquatic insects.<\/p>\n

\u2463 Insects<\/p>\n

Mosquito larvae, daphnia, nymphs, dragonflies, spiders, frogs.
Each ate, were eaten, and then returned to the soil.<\/p>\n

This miniature ecosystem existed in each rice paddy.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t

The dragonflies were not \"killed and disappeared\" but returned to their natural state. This small ecosystem existed in each rice paddy.<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Here’s the important point.<\/p>\n

Dragonflies weren’t suddenly killed in large numbers.<\/p>\n

In many cases,<\/p>\n

– The nymphs weren’t developing.
– There were no insects for them to feed on.
– There were few bacteria in the water.<\/p>\n

Even after they were born, they stopped reproducing.<\/p>\n

In other words,
The cycle stopped, and they quietly disappeared.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The biggest change is that<\/p>\n

– Pesticides that wash away easily
– Pesticides that last longer
– Pesticides that affect insects’ nerves<\/p>\n

are now being used in rice fields.<\/p>\n

Fewer insects
\u2192 Less droppings and carcasses
\u2192 Less bacteria
\u2192 Water quality weakens
\u2192 Larvae don’t develop
\u2192 Dragonflies can’t return<\/p>\n

Once this cycle starts, it’s hard to stop.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Rice fields today look beautiful.<\/p>\n

There are no weeds and the water is clear.<\/p>\n

But the beauty of an absence of living creatures also means
a still, tranquil atmosphere.<\/p>\n

Rice fields in the past were murky, full of insects, and required a lot of work.<\/p>\n

But on the flip side, they had the ability to recover on their own.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Rice fields without dragonflies
may not be in immediate trouble, but they are vulnerable in the long run.<\/p>\n

– More outside influences enter.
– More human management is required.
– Even the slightest abnormality can cause the fields to collapse.<\/p>\n

This isn’t just a problem for rice fields.<\/p>\n

It’s also connected to water, soil, food, and people’s bodies.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The reason dragonflies used to abound in rice fields
is not because nature was abundant.<\/p>\n

It’s because soil, water, bacteria, and insects were circulating properly.<\/p>\n

Dragonflies simply flew along the way in this cycle.
And now is the time for us to remember this cycle once again.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
