And if you look at the species level, you saw about fish.

It has no vegetation.

Water is a natural resource of vital importance.

And these are not esoteric limits.

Where is all that water going?

And if we have abundant energy, we also have abundant water.

Water is a natural resource of vital importance.

Let's conserve our limited water supply.

Let's conserve our limited water resources.

Second, ice caps and polar regions freeze up to 70 of the planet's fresh water.

Salmon lay their eggs in fresh water.

And you hear the words scarce resources a lot when people talk about economics.

Water, forests, and minerals are important natural resources.

They need fresh water to breed.

So it's essentially a freshwater animal.

Where do they get their water? Where do they get their shelter?

The water in lakes and rivers is usually fresh.

But dragonflies a bit tricky.

He owned the water department?

They lay the eggs into fresh water.

Salt water is more buoyant than fresh water.

That was one of those turning points where I said, wow what am I doing here?

For example, love might not be a scarce resource. You might have an infinite amount of love.

Even if they were sincere, they don't know how to solve problems.

And economics is very interested in scarcity.

Resources.

Well, that's the future we have to look forward to.

Water and Power?

Growth of use will consume any energy or resources saved through conservation.

So, who is next? Us?

You were in what they called the saltwater camp, meaning Harvard, Princeton, MlT, Stanford, Berkeley, or you were in the freshwater camp, University of Chicago,

(Applause)

I believe this fish is a freshwater fish.

Green, Latin America, East Europe.

And then the adult, which comes after, lives for one or two months.

A desalination technique that can yield potable water within seconds.

A depth of 40 meters...

In order to restore the bond, we need to utilize regional resources.

An analogue would be the growth of bacteria in a petri dish.

And one thing you need to know about dragonflies, one important thing, is that they lay their eggs in fresh water.

They are the happiest place.

So I asked the Minister over dinner,

I suppose we'd better take Water and Power first.

Then it was over the water department.

In the news, the subject of where our future water is going to come from and where our power is going to come from is in all the papers all the time.
