water's interview

this interview was made to my father who has been studing about the water in the world.
Julio (junior): "can you tell us the percentage of water in the world?"
Julio (father): "the percentage of salty water in the world is of 97% and sweet water is of 3% of that 3% only the 30% is potable, the other 70% corresponds to glaciers, but this percentage its going to diminish drastically because of the global warming".
Julio (jr): "how does the human polute the water?"
Julio (father): "principally with the liquid wastes of the industries and with the black water and grey water of the cities and towns".
Julio(jr): "does the human is concious of this?"
Julio (father): "the goverments of the first world countries (USA, Japan, Italy, France, Germany, Canada, England and Russia), and the internacional organizations like the ONU and the UNESCO for more than 30 years are making campaings and meetings with the purpose of analize the global problem of decrease of potable water, to look for solutions as for tell this situation to the rest of the world".
Julio (jr): "what are the countries that polute the most the potable water?"
Julio (father): " they are the USA, China and India.
Julio (jr): " what are the countries that have the smallest quantity of potable water?"
Julio (father): "they are (principally) Australia and the 90% of African countries".
Julio (jr): "what can we do to save the water?"
Julio (father): "this is a job that must be done in all the levels of the states and societies. The states must make harsh laws and make shure societies (industries and civils) know them and accomplish them, understanding that this laws must be based in avoiding the polution of potable water, but also in the saving of clean water and the recicling of the gray water".
Julio (jr): "ok dad, thanks for the information, and i hope you continue studing about water".
Julio (father): "thank you son for your questions about this topic that is very important for all the world".

water's song

the laste glacier

I

this is our world,

the only one we have,

but we treat it bad,

like an ugly rat.

II

the TV is always there,

the water dont,

so take care,

if you want to live a lot.

CORUS

the water,

please save the water if you dont want to,

lose it.

IV (talking)

just dont waste it, see that life depend on it, only 3 minutes on the shower, only using the energy you need, only throwing trash to the trash can, all this actions can save our world its easy do you see?

water caracteristics

We can tell the caracteristics of water from 2 different points of view: physically and chemically
Physically: its transparent, is liquid and very easy to change its physical form.
Chemycally: its formula is H2O, its atomic number is 10 its weigh is 18 uma, its energy level is greatest than the energy level of the solids and its density is lower than the solids's one, thats why it adopts the form of the place in which it is.

water in Colombia

The cleanest water in Colombia is the Bogota's one but naturaly its the dirtiest one ( refering to the bogota's lake), because all wastes we throw to the rivers, the ocean polutes too making Barranquilla's Cartagena's Santamarta's and many other water that is in the coasts, principally that places have the worst water, not only because the rivers that contaminates the ocean, it is also because the ports that have boats with chemics that in most of the times, because
accidents, go to the ocean, and because the oceans feed the river's flow, so the zones in Colombia in which river's flow are feed by the contaminated oceans have the unhealthiest water in Colombia, but not only the worse water in the rivers, but in the fresh water we use to take showers because, if the river's water is very poluted its going to be hard to clean it to take showers, so the water we use to take showers will not be totaly cleaned, but, Why if in Bogota the river is so poluted the fresh water used to take showers, drink and wash the hands is the cleanest in Colombia? Easy, the water descontamination technology, Bogota is the city with most technology in Colombia so water descontamination is easiest, and also because in Bogota the water descontamination plants dont use too much Bogota's river water, they use a cleanest one.
In conclution, the contamination in Colombia's rivers and fresh water depends in many factors, like the ocean, water descontamination technology level, and any kind of wastes the Colombia's people throw to the rivers.

the water status

the water status

As you know, sins our aparition on earth we depended on, mainly, on water, our specie depends mainly on water, as many other species, but, with the new technology we found another way to use water, not only to drink it, the water can be used to take baths, produce energy, throw wastes, in the industries... but with all this uses the water is starting to end, at least the fresh water, the only kind of water that the human and anotheer species can drink. But we dont only waste it, we also polute it throwing human, industrial and many other types of wastes, we are assuring our specie's, and other specie's extinction. normally, the amount of fresh water on earth is of 3% but now at days is decreasing.

there are 3 main water resousces in earth, lakes, rivers and glaciers.

because the global warming the glaciers are smelting and moving to the ecuator, this increases the sea level and cause the floods, but the water produced by the melting of glaciers becomes dirty because it passes throug the contaminated water, just because it melted

earlier.

this was a glaciar and the same glaciar in 2009.

But the good news are that people are begining to be more concious about water, for example, here, in Bogotá the water consume decreased.

In conclution, water in earth is decreasing at, but if we take care of the water, like dont washing the car, closing the faucet when you are going to use the shampoo or the soap, decreacing the CO2 level in the artmosphere and dont throwing wastes to the ocean, we will save the water and the environment in earth.
