In other words, when they are living, by these creatures living here plants are allowed to live, and by these plants living here small creatures are allowed to live.

You don't have any plants or animals, right?

Plants grow.

I mean it's not like they have angle a trons.

Organisms don't think of CO2 as a poison.

No animal can exist without plants.

I'd love to have an opinion of a paleobotanist as well.

But my passion in addition to Jack and my children are the plants, the so called epiphytes, those plants that grow up on trees.

That's your water that helps to make the cloud that becomes the rain that feeds the plants that feeds the animals.

I devoted half of it to rebuild the herbarium, because we didn't have good infrastructure to start plants.

Botany deals with the study of plants.

So you can remove 90 percent of the root apparatus and the plants continue to work.

They don't have roots that go into trunks nor to the forest floor.

Animals and plants have the right to live, and men even more so.

The other side stays dry, no liquid comes out there.

And this is a living organism that has a mass of at least 2,000 tons.

Zoology and botany deal with the study of life.

We need plants in order to live.

(Laughter)

So here's the next challenge.

They eat it, process it through their bodies and you end up with worm poo, you know, which is soil, which feeds the plants.

As it's gotten warmer on the top of the mountain, the vegetation zone is actually changing.

This sediment is 100 percent made up of the shells of microscopic plants.

We harvest the wheat, and in harvesting it, we kill it.

This is something called an underground forest.

Epic battles between carnivores like these are just one way to get food.

If it were not for plants, we wouldn't be able to live.

They are able to distinguish kin and non kin.

Plants give off oxygen as they make food.

This is the aldertree.

This is our paleobotanist, Dr...

But we've also discovered, when it comes to plants, in plants, as much as we understand and are starting to understand their genomes, it is the ecosystem around them, it is the microbes that live in their root systems, that have just as much impact on the character of those plants as the metabolic pathways of the plants themselves.

The slope which is coming, which we call a Red Edge, is a detection of vegetated area.

I spoke to a biologist at the Kirstenbosch Botanical Garden in Capetown to ask him where he thought this remarkable plant came from, and his thought was that if you travel around Namibia, you see that there are a number of petrified forests, and the logs are all the logs are all giant coniferous trees, and yet there's no sign of where they might have come from.

What do they do?

And in a rice paddy, a lot of life forms, including creatures and plants, forming a unity, forming one body, they are living.

This is the most successful order on the planet by far.

It seems to have organic life.

Plants are even able to communicate they are extraordinary communicators.

Continuation of their lives as plants is a blessing for them.

like a social network.

(Laughter)

Such red clay is not found within a hundred miles of Edinburgh, except in the botanical gardens.

It's the flooding. It's the excess soil.

I'm seing beauty created on the land
