I said, What can you build in this place?

To change the community you have to change the composition of the soil.

But what are the conditions that make it possible?

Should aluminum be in the soil and the rain?

Plants are nourished by earth.

The rain washed away the soil.

I collect soil samples.

The soil retained richness.

which is going to cause air pollution, water pollution,

Large scale use of pesticides and fertilizers raised concerns of soil pollution.

They're good for the environment because they enable no till farming, which leaves the soil in place, getting healthier from year to year slso keeps less carbon dioxide going from the soil into the atmosphere.

Worms are sometimes beneficial to soil.

Plants take in water from the soil.

Water resources are running low.

Every sound the child hears uncorrected is muffled.

We are after all organic creatures, and the culture of the school is absolutely essential.

She gets the women to plant new trees and water them, drop by drop.

That soil is rich in humus.

You can't get a tree to grow on bad soil.

So we would take the landscape and we would build up the topography.

Shredded ozone layer, global droughts, toxified soils, poisoned populations.

The mycelium infuses all landscapes, it holds soils together, it's extremely tenacious.

Our farming has done the opposite.

Then, if we added maps like the geology, the bedrock geology, and the surface geology, what the glaciers leave, if we make the soil map, with the 17 soil classes, that are defined by the National Conservation Service, if we make a digital elevation model of the topography that tells us how high the hills were, then we can calculate the slopes.

No sign of environmental degradation.

Rich soil yields good crops.

And this is the concept for the top of the city.

Abiotic stress is the drought.

curiosity without assumptions.

It's kind of hard to explain. I guess it's in the loam of the soil.

Another important point of these sand banks is that when it rains, the rainwater soaks down into the soil.

Some of it ran off as flooding, but most of the water that soaked into the soil simply evaporated out again, exactly as it does in your garden if you leave the soil uncovered.

I'm reading massive cellular deterioration.

We have a massive ozone hole in the Northern hemisphere now.

And we do a lot of work here.

I'm sorry, Arnold, your physical data disc has become corrupted,

Nothing seems to grow in this soil.

Once or twice a year I'd go an' work at 'em a bit prune 'em an' dig about th' roots.

In order to get the soil ready for planting you must plow it.

Not a sign of age or wear on any of it.

I also learned that some of our tastiest mushrooms can clean environmental toxins in soil.
