One of them was the remarkable gharial.

In fact, if you see the map, the range of their original habitat was all the way from the Indus in Pakistan to the Irrawaddy in Burma.

The second of these is the biophony.

The grasslands were sweeping away.

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.

And these would be the kind of trees that might have been there, and the flowers and the lichens and the mosses, the butterflies, the fish in the stream, the birds in the trees.

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.

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

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

One of these diseases, chytridiomycosis, has driven stream dwelling amphibian populations to extinction in Africa,

It may seem counterintuitive, but it accounts for little streams all over the planet.

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

So, we studied the fish and the frogs and the birds and the bees, the 85 different kinds of fish that were on Manhattan, the Heath hens, the species that aren't there anymore, the beavers on all the streams, the black bears, and the Native Americans, to study how they used and thought about their landscape.

Where do they get their reproductive resources?

West Bank

We build cities, suburbs, and farms on top of frog habitat and chop forests and drain the wetlands that serve as home for numerous amphibian populations.

Landscape ecology concerns itself with how the stream and the meadow and the forest and the cliffs make habitats for plants and animals.

Tension in the West Bank continues. Shots were fired at an army post near Nablus.

This song is from Mesopotamia which means The land between the two rivers the Tigris and the Euphrates, where the homo sapiens learned to write, to count, and mark the stars.

But they're also mapping things of ecological interest, also military interest the hills, the marshes, the streams.

Their habitat is threatened by deforestation.

The blue lines on the map represent rivers.

The more these people work, the mountain will be destroyed more.

I had to get off the streets.

The locals call this river the man eating river and fear it.

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,

There are millions that I could choose from and this is it it's called the jewel wasp.

Nirvana, the great void.

Yes, from the Bethmora clan, the Suns of the earth.

The basin of a river usually has rich farmland.

Blue lines on the map designate rivers.

My land abuts on the river.

the ospreys cried from the sandy river side

But, in fact, they're grassland habitats for grassland birds and plants.

And if you look north here, there's a big river that flows into the lake that's been carrying sediment and preserving the remains of the animals that lived there.

Sir? Mr. Crouch's son.

The river is widest at this point.

So in habitats that have already been damaged,

But this is crucial habitat and it's where they spend the first two, three years of their lives, until they're big enough to go out on the rest of the reef.

The locals call this river the man eating river and fear it.

It's a land known to the Tahltan people and all the First Nations of British Columbia as the Sacred Headwaters, the source of the three great salmon rivers of home, the Skeena, the Stikine and the Nass.

The polar bear, which lives on the polar ice cap, will lose its home and die out.
