Preschool maybe.

I'm thinking about complaining about my son's teacher at the kindergarten.

This was happen to spread.

And you can see immediately what happened, right?

There's more violence in your kids' nursery schools.

So Gneezy and Rustichini said,

My son's still at daycare.

Boom. No ifs, ands or buts.

Now as you ponder that question, maybe you're thinking about the first day of preschool or kindergarten, the first time that kids are in a classroom with a teacher.

And this has become such a cultural norm that we actually school our children for them to be capable to do this cleavage.

The second of these is the biophony.

On Todagin Mountain, revered by the Tahltan people as a wildlife sanctuary in the sky, home to the largest population of stone sheep on the planet,

larger biomass inside the reserves.

This is in the Bahamas Nassau grouper.

Get him out of here.

I hear some guy, presumably a caretaker, going Rawr, I'm going to eat you! from the nursery school across the street.

Over many decades I travelled throughout the world as a journalist, and she devoted herself to her job at the daycare center.

What happened to our JanDi?

The youngest child spent every morning at a nursery.

And watch the change as it goes into this long dry season.

Level 6 ... a funfair!?

The grasslands were sweeping away.

The white group there is the control group they change nothing.

Could you please pick Shigemi up for me at the day care center?

We ask to extend the time our kids can stay at the nursery, because we can't leave work to pick up kids before the school closes.

Week 44 I met Ken, the Director of a preschool in Boise, Idaho.

They were too young to survive without their mother.

Hold on, this isn't some species that was obliterated by deforestation or the building of a dam.

Seemed kind of chummy with him.

And so they went and studied 10 daycare centers in Haifa, Israel.

So what happened?

I was very touched when I saw a breakthrough the other day.

And inside, we have this area for reforestation as a gene bank to keep all that material alive, because for the last 12 years not a single seedling of the tropical hardwood trees has grown up because the climatic triggers have disappeared.

With an average depth of the oceans of 4,000 meters, in fact, the high seas covers and provides nearly 90 percent of the habitat for life on this Earth.

I left San Francisco, where I live, on Monday, and I was getting on the plane for this conference.

Heaven on Earth.

And I'm working at all the energy I have to sort of communicate this message that we need preschool, we need Head Start, we need prenatal care.

This is the power of darkness...

It supports wild fish including cutthroat, brown and rainbow trout.

And eventually, the deep sea floor would come into view.

Habitat destruction is the number one problem for frog populations around the world.

That is the primary function of an incubator.

The childminder cares for between one and three children.

And this is what they ended up coming with.

Where do they get their reproductive resources?
