Okay, so I'm going to take this really filthy water, and put it in here. Do you want a drink yet?

Drink In modern times, water is seen as a common choice to drink with a meal.

We get droughts, increased desertification, crashing food systems, water scarcity, famine, forced migration, political instability, warfare, crisis.

The days and weeks that followed, people fleeing to the hills, being forced to drink contaminated water or face death.

Instead of shipping water, and using man made processes to do it, let's use Mother Nature. She's got a fantastic system.

These people pioneered the growing of grains in the extreme conditions of aridity, thanks to the high water tables of Southern Iraq.

So, by thinking differently, and processing water at the point of use, mothers and children no longer have to walk four hours a day to collect their water.

DK This next project, we were asked to design a pavilion to celebrate the recycling of the water on the Millennium Dome in London.

He recovered the box and opened it, finding that it contained what looked like body parts wrapped in brown paper.

Fine city of Oxford, so what I've done is I've gone and got some water from the River Cherwell, and the River Thames, that flow through here. And this is the water.

And as we were preparing to come back from the burial, the cars stopped at the bathroom to let folks take care of themselves before the long ride back to the city.

It is the second most common type of electricity generating nuclear reactor after the pressurized water reactor (PWR), also a type of light water nuclear reactor.

And that ephemeral nature of the hydrothermal vent community isn't really different from some of the areas that I've seen in 35 years of traveling around, making films.

Only nine destroyers were sunk by air attack in 1940, out of a force of over 100 operating in British waters at the time.

And with a population increasing as quickly as it is, and with the water supply from these glaciers because of climate change decreasing so much, I think we have a real risk of instability.

The high seas, where whales, tuna and dolphins travel the largest, least protected, ecosystem on Earth, filled with luminous creatures, living in dark waters that average two miles deep.

We need initial upfront investment to train doctors, nurses, health administration and community health workers throughout the country, to set up the information technology, the solar energy, the water and sanitation, the transportation infrastructure.

Adding a measurement to that is interesting the falling water suddenly gives you a sense of, Oh, Brooklyn is exactly this much the distance between Brooklyn and Manhattan, in this case the lower East River is this big.

And then, if you saw, the panels actually rotate. So you can get the information on the front side, but as they rotate, you can see the actual recycling plant behind, with all the machines as they actually process the water.

Look at this diagram, which is showing warm waters in red, cool waters in blue, and on the continents, what you're seeing in bright green, is the growth of vegetation, and in olive green, the dieback of vegetation.

Barbarically, we're killing sharks for shark fin soup, undermining food chains that shape planetary chemistry and drive the carbon cycle, the nitrogen cycle, the oxygen cycle, the water cycle our life support system.

That may have been true 10,000 years ago, and maybe even 1,000 years ago but in the last 100, especially in the last 50, we've drawn down the assets, the air, the water, the wildlife that make our lives possible.

And because I'm an underwater photographer, I wanted to do this story from both above and below, to make pictures like this that show one of these little pups making its very first swim in the icy 29 degree water.

I hear you and I know that you would want me to be strong, but right now, I am being sucked down, surrounded and suffocated by these raging emotional waters, craving to cleanse my soul, trying to emerge on a firm footing one more time, to keep on fighting and flourishing just as you taught me.

It's money that's invested in entrepreneurs who know their communities and are building solutions to healthcare, water, housing, alternative energy, thinking of low income people not as passive recipients of charity, but as individual customers, consumers, clients, people who want to make decisions in their own lives.

Too much of the world lacks access to clean drinking water. Engineer Michael Pritchard did something about it inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. An amazing demo from TEDGlobal 2009.

According to a paper written by two academicians, the rapid growth of the pernicious weed is caused by the inflow of nutrient rich water from urban and agricultural runoff and products of industrial waste, threatening other Ethiopian lakes as well such as Lake Hawasa, and Lake Zeway.

In every case there's a lot of variation, but something about the environment the people are living in, and I think the only realistic explanation is that it's the degree of waterborne transmission, favored the harmful strains in one place, and mild strains in another.

If you look at the country from above, the rivers, canals, and water based activities are quite a sight. The diversity of this river related life is also captured in Shamim Sharif Susom's photos that he usually takes from 500 1,000 feet in the air.
