Rich Forests for Soil, Fundamental Solution for Yellow Sand and PM2.5

Perhaps the speed of the collapse of nature in the world is increasing. 

The new coronavirus is well-publicized, but I'm more interested in "yellow sand" and "PM2.5". So I check those updates as much as the weather forecast.

Air pollution is now serious all over the world

Difference between "yellow sand" and "PM2.5"

"Yellow sand" is sand and mineral particles that are blown by the wind blowing in the Uighur district, around Mongolia, and in dry areas such as deserts inside China. It will be transported to Japan from February to May by the westerlies. On the other hand, "PM2.5" is a general term for particulate matter with a particle size of 2.5 μm or less that floats in the atmosphere. Both cause health hazards such as runny nose, itchy eyes, fatigue, etc.

Countermeasures

Countermeasures include:

• Check yellow sand and PM2.5 information every day.

• Japan Meteorological Agency | Yellow sand information 
• PM2.5 distribution prediction -Japan Weather Association tenki.jp

• On days with a lot of yellow sand and PM2.5, go out as short as possible.
• Do not open the window on days when there is a lot of yellow sand and PM2.5.
• Dry the laundry indoors, not outside.
• Use a PM2.5 compatible mask.
• Immediately after returning home, wash your hands, gargle, eyes, and face.
• Use a PM2.5 compatible air purifier indoors.
• Wear glasses when you go out, etc.

What is a Fundamental solution?

Deforestation is said to contribute to air pollution. From another point of view, forests have an air purification function that absorbs harmful pollutant gases and detoxifies them, and dust is adsorbed by leaves.

So how can we regenerate the forest abundantly? 

Small insects and microorganisms decompose the fallen leaves to enrich the soil. Most of tree-planting activities, which are common environmental protection activities, are unfortunately wrong. Because they plant cypress that does not fall leaves.

Rich forests made by fallen leaves enrich the soil, store water in the soil, run clean rivers and join the sea. Therefore, forests are closely related to the environment of rivers, the sea and the atmosphere.　In other words, we will see the beautiful sea and know the rich forest.

Forest in Japan now

The forest area of Japan is about 25 million hectares, and 67% of Japan's land and two-thirds of the land are forests.  Even in Japan, which is said to have many forests, large-scale logging and planting of remote forests has been carried out in the last 100 years for economic reasons. 

As a result, it has destroyed a large amount of the original nature. In unhealthy plantations with only coniferous trees such as cypress, the function of storing water and biodiversity are reduced, and weather damage such as fallen trees and collapses is likely to occur.

Autumn leaves are a sign of the richness of the soil. 

What I hope when the sky becomes muddy

One thing I can't help but hope when the sky becomes muddy. It is a rich forest.

Conclusion

Recently, yellow sand and PM2.5 have begun to afflict us. Perhaps the speed of the collapse of nature in the world is increasing.  The fundamental solution is to expand the forest where the fallen leaves enrich the soil. Rich forests enrich the sky, rivers, seas and the earth.
