`` Water making'' development story Water story Part 3 Shooting in Zaire

"Good water" is

Put "good soil", granite and volcanic rock together in the aquarium,

Made by circulating with aeration.

However, if "good soil" is left as it is, it will melt in, so

It was used by solidifying the raw material soil into pellets with "glue".

Powdered "good soil" was used for wastewater treatment, composting, and soil improvement.

I photographed the site of Kyushu where "good soil" is produced.

There was a factory that digs and processes soil in the place where four 400m trucks can be taken.

Dr. Uchimizu called each "good soil" the "best soil" on the planet.

According to interviews with neighboring farmers, no fertilizers or pesticides are used in all crops.

Moreover, there are no insects.

I don't get sick.

The quality is the highest level.

However, because it is small, it is self-sufficient and consumed in the neighborhood without shipping.

"Teacher, what should I use after that when the soil here is gone?"

The teacher's answer to my visit is

"People have no choice but to make something close to the best soil.

"Can people make it?"

"I can't make the best soil, but I can make something close to it!"

"Hmm ???"

I have a big homework left.

In the fall of the year when "Natural Science of Soil and Water" was created,

In the program coverage of "Wild Kingdom" (produced by Mainichi Broadcasting System)

I went to Zaire (now the Republic of the Congo) in Africa for coverage.

The first place I visited was "Virunga National Park".

In the caldera basin of a huge volcano tens of thousands of years ago,

The basin isolated from the surroundings has just been designated as a natural park.

When you cross the outer ring mountain, enter the park and run on the plain,

"What is this !?"

I jumped into my eyes.

In the meadow

Hippos, cows, big and small gazelles, big storks, even lions

Closely next to each other

It's filled as far as the eye can see.

If you take a closer look with binoculars,

Desert warthogs and large lizards can also be seen in the grass,

There are countless feelings about small birds.

I didn't catch all these creatures

In order to protect the place that has lived like this since ancient times

It was designated as a "national park".

That's why this situation has been going on for a long time.

"... That's it !?"

“No matter how rich nature is

So many herbivores eat every day,

Isn't there enough grass? ”

Such my question has not yet been put into words.

The Zaire River (a tributary of the Congo River) crosses the center of the national park.

Flocks of hippos are sinking all over the riverbank

Raises a peculiar bark as "bububububu".

The small swamps in the grasslands are also soaked with hippos and hippos.

Turn the rice scoop-shaped tail around to remove feces.

The hippos' backs are full of feces because they fly alternately and seamlessly.

The water surface in the gap is also filled with feces.

It flew to me as I was watching,

Curiously

It didn't smell at all.

I asked the ranger that night.

That flock of hippos is divided into each harem,

At dusk, the food clerk also went out to the grasslands with the female at the head,

He said he would eat all night and come back to his place before sunrise.

The amount of grass that a hippopotamus eats overnight is 60 to 70 kg.

The average weight of an adult hippopotamus is 6-7t.

The sight of such hippos going out to eat in a line

If you apply for shooting that it will be spectacular,

I was immediately turned down.

The hungry hippopotamus is very ferocious and you can easily turn over the interview car etc.

It is said that people and cars will be messed up with fangs that are 40 to 50 centimeters tall.

It was good if I came back at dawn, so

I decided, "OK, let's take a picture of the hippopotamus on the morning trip!"
