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

They lay the eggs into fresh water.

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

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

Where is all that water going?

Salmon lay their eggs in fresh water.

They need fresh water to breed.

So it's essentially a freshwater animal.

The water in lakes and rivers is usually fresh.

But dragonflies a bit tricky.

Salt water is more buoyant than fresh water.

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

It's a waterborne disease, not something that's in the air.

The second of these is the biophony.

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,

I believe this fish is a freshwater fish.

Green, Latin America, East Europe.

Most of the water on Earth is ocean, a salty 97.5 , to be precise, and the remaining 2.5 is fresh water.

A desalination technique that can yield potable water within seconds.

I had my son water the lawn.

I had my son water the lawn.

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

The grasslands were sweeping away.

When the water goes down, they know what to do.

Because who wants the fertilizer factory that makes natural gas?

The river was alive with fresh water fish.

Such fishes as carp and trout live in fresh water.

Such fish as carp and trout live in fresh water.

Fish such as carp and trout live in fresh water.

Fish like carp and trout live in fresh water.

So you can generate electricity from the gas turbine, and you've got to cool the gas, and every thermodynamic cycle has to reject waste heat.

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.

Aqua expresses the colour of clear water, it is a bright, and light, blue.

You have on the y axis some good thing biodiversity, numbers of orca, the greenness of your country, the water supply.

This was taken in the old Croton Aqueduct, which supplied fresh water to New York City for the first time.

All the liquid water above ground is surface water and it is a tiny blip of an amount.

So it's a floating island with water, fresh water, that can fly from place to place.

And this is detrimental to the local ecology of the sea area that it's pumped back out into.

And the desalination process is one where we take out salts.

So we actually sort of designed the entire island as a single ecosystem, exploiting wind energy to drive the desalination plants, and to use the thermal properties of water to heat and cool the buildings.

This device made it possible to turn sea water into fresh water easily.

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.

The fresh water from the berg creates a pool of fresh water that can extend a nautical mile away from the iceberg.

Not only is it coming out of the Earth so, biogenesis made from volcanic activity but that bacteria supports these colonies of life.
