Las cifras de la UNESCO son contundentes. En la actualidad, de la población total del mundo —6 mil 684 mil millones de personas— casi una tercera parte sufre escasez de este líquido. Y en un lapso de 10 años, la oferta de agua potable, que hoy anda sobre los 14 mil millones de metros cúbicos, podría reducirse hasta 70%.
Paradójicamente, 70% de nuestro planeta está formado por agua, aunque sólo 3% de ésta es apta para consumo. La posibilidad de un mundo sin agua es más que una realidad: es casi una tendencia irreversible.
Sin embargo, no todo está perdido. Eduardo Cortés, director general de GE Water México, aclara que aún hay tiempo de tomar medidas preventivas, pero también de invertir en tecnología capaz de revertir el proceso. Y la desalinización es una opción que con los años se convertirá en un proceso común.
Es necesario potabilizar el agua de mar, hacer posible su consumo.
Para lograrlo se utiliza un método denominado ósmosis inversa (también conocido genéricamente como nanofiltración), que consiste en filtrar el agua a través de diversas membranas permeables al agua pero que “retienen” la sal y otras impurezas.
El agua de mar contiene entre 33 y 37 gramos de sólidos disueltos por litro, para potabilizarla se requiere remover 99% de estos sólidos. En algunos casos, el agua es sometida también a un proceso químico conocido como “ultrafiltración” que elimina cualquier residuo microbiológico.
Según la International Desalination Association, operan en el mundo 13 mil 080 plantas purificadoras, cuya capacidad total es de 55.6 millones de metros cúbicos de agua potable al día (apenas 0.5% del uso mundial).
“La tecnología de desalinización ya se usa en México —comenta Cortés—. En hoteles de La Paz, Ixtapa, Puerto Vallarta”. El directivo aclara que se trata de plantas pequeñas, y que su uso aún es marginal.
Sin embargo, existen plantas de tamaño mayor, capaces de surtir de agua ciudades enteras. Es el caso de Algiers, la capital de Argelia, donde plantas valuadas en 200 millones de dólares abastecen a 2 millones de habitantes, potabilizando 200 mil metros cúbicos de agua salada al día.
Según los análisis de la firma Global Water Intelligence, el uso de estas tecnologías se duplicará de aquí al año 2015.
Este incremento se debe también a que los costos han disminuido.
A principios de los 90, el metro cúbico de agua desalinizada costaba 1.5 dólares; el precio actual anda sobre los 70 centavos.
En varias ciudades, incluidas Londres y San Diego, ya se planea la construcción de plantas desalinizadoras. No sucede lo mismo en el caso de nuestro país.
“En México seguimos utilizando tecnologías de antaño, sin invertir en nuevas opciones —concluye Cortés—. Si no tomamos medidas pronto, en menos de 20 años podríamos vernos en serios problemas”.

hello...
plase dont angry me......
i inform you about Islam acording to Islam.
BISMILLAH AR RAHMAN AR RAHIM (In the name of Allah Most Gracious Most Merciful)
Peace to all who follow hidayath (guidance, the correct path)!
Islam…for whom? For every person upon whom Allah has bestowed life and intellect. For those who can see the blessings of Allah. For those who can hear the Words of Allah. For those who can comprehend the evidences of Allah. For those whose hearts are full of love and gratitude to Allah. For you, for me, and for those whose blessed hearts are open to faith in Islam.
I invite you to Islam for your eternal happiness. Eternal felicity, salvation and peace are in Islam. Goodness and light are in Islam. I just want to warn you at facing to terrible penalty. There is no compulsion in Islam and I don't force you. Because Hidayath (İslam:the correct path) is distinct from error. Allah jalla jalaluh is An-Nur: He who gives light to all the worlds, who illuminates the faces, minds and hearts of His servants. Allah is Al-Haadi. He who provides guidance. The true guidance is light from Allah. You are at the Presence of Allah and you should alone invoke Allah that Allah illuminated your face, mind and heart (spiritual) and provided your guidance. Allah is Al-Mu'min: He who awakes the light of faith in our hearts.
Allah is At-Tawwab: He who is ever ready to accept repentance and to forgive sins (Relenting)). Narrated by Abu Sa'id Al-Khudri (may Allah be pleased with him) - Allah's Messenger (pbuh) said, "If a person embraces Islam sincerely, then Allah shall forgive all his past sins, and after that starts the settlement of accounts: the reward of his good deeds will be ten times to seven hundred times for each good deed, and an evil deed will be recorded as it is unless Allah forgive it. 'Wouldst thou that thou shouldst be purified (from sin)?
Human being certainly prone to evil unless my Rubb (Lord) do Bestow His Mercy). You never must submit Satan. Because satan great enemy for mankind. You should not submit absolutely except Allah. Because Allah is your Rubb (The Lord). Mankind should not obey own self desires, passions, feelings, prejudices and whispers of Satan. You shouldn't be one of arrogant and ignorant humans. Be resolute to enter Islam (the only true way, the Straight Way). Please you should not afraid of truth.
; and if any one believes in Allah (The Only One Ilâh), (Allah) guides his heart (aright): for Allah knows all things. ((64)At-Taqhabun: 11)
Qur'an is the remembrance of Allah and is stated in the Qur'an: "Those who believe (for Muslims), and whose hearts find satisfaction in the remembrance of of Allah: for without doubt in the remembrance of Allah do hearts find satisfaction. (13: 28)
You should return to the Path (Islam) of Allah (Allah is alone worthy of worship). Allah revealled to Prophet Muhammad (pbuh) and is stated in the Holy Qur'an: And those who strive in Our (cause), - We will certainly guide them to our Paths: For verily Allah is with those who do right. (29: 69)
Life is trial and is stated in English Translation of the meaning of the Holy Qur'an: The life of this world is only the enjoyment of deception (a deceiving thing). "Everyone is going to taste death, and We shall make a trial of you with evil and with good, and to Us you will be returned."(21: 35)
Allah hath promised to Believers (Mu'min, one who has faith in Islam), men and women, gardens under which rivers flow, to dwell therein, and beautiful mansions in gardens of everlasting bliss. But the greatest bliss is a good accaptence from Allah: that is the supreme felicity (triumph). (A-Tawba, 72)
For those who respond to their Lord, are (all) good things. But those who respond not to Him,- Even if they had all that is in the heavens and on earth, and as much more, (in vain) would they offer it for ransom. For them will the reckoning be terrible: their abode will be Hell, - what a bed of misery! (Ar-Rad, 18)
By (the Token of) Time (through the ages),
Verily Man is in loss,
Except such as have Faith (Faith in Islam), and do righteous deeds, and (join together) in the mutual teaching of Truth, and of Patience and Constancy. (1, 2, 3; The Surah Al-Asr (103))
Allah jalla jalaluh revealled Prophet Muhammad (pbuh): Say: "What has come to me by inspiration is that your Allah is One Allah: will yet herefore bow to His Will (in Islam)?" (21: 108)
It is very easy to accept Islam, only one Haqq ( absolute truth) Deen ( deen, the completely way of life). Your repentance is the testimony of faith. Revive by holding fast to the Rope of Allah (Qur'ân). At first you must reject Taghut (Anything worshipped or obeyed other than Allah (jalla jalaluh)). Sincerely Say Shahada (Confession of a Muslim) for your eternal felicity and Do rescue! You should convert from kufr (denying Islam) and shirk (to float true and error) to Islam. Submit your will to Islam and escape monotony: 'ESH'HADU ANLA ILAHE ILL'ALLAH, WA ESH'ADHU AN'NA MOHAMMED'EN ABDUHU WA RASULUHU'
I bear witness that there is no Ilâh (worthy of worship) except Allah (The Only One Almighty, Only One Rubb (Lord)) and Allah has no partners; and I bear witness that Muhammad is His abeed (servant) and Messenger.
O mankind! Do your duty to your Lord (Rubb) by fearing Allah, and avoid (the coming of) a Day when no father can avail aught for his son, nor a son avail aught for his father. Verily, the promise of Allah is true: let not then this present life deceive you, nor let the chief Deceiver (satan) deceive you about Allah. (The Holy Qur'an 31: 33)
THE REASONS OF KNOWING ISLAM WRONGLY: 1- Unfortunately, Most of human exactly does not know Islam according to Islam. Most of mankind has lost its own sense faculties because those people are in comfort, amusement, has the passion of earn much money. Most of human is in being drunk of amusament, football, music, secularism, ideologies. Sustanance and blessings are not favour of Allah. They are all handle of trial. Satan shows evil to Islam to Non-Muslims. By going through the teachings of Islam, it is clear that such a religion has only come to benefit mankind - not to destroy it. So why is there so much hatred for this noble religion in the West? The answer is simple, the media. It is the Jewish influenced media of the West which has portrayed Islam to be something that it is not. Those are who wanted to deceive human beings, always attack Islam. With regret, some people knowingly change translations of Holy Qur'an. This unkind behavior causes that some people can misunderstand Holy Qur'an. Learn Islam from true sources. Islam have illuminated universe. Islam is the soul of universe. Some people can not understand Qur'an and completely can not profit by Qur'an since they have not belief in hereafter. Belive hereafter acoording to Islam.
Your Allah is One Allah, Allah is alone worthy of worship). But for those who believe not in the Hereafter, their hearts deny (the faith in the Oneness of Allah), and they are proud.(16: 22)
Had We sent down this Qur'an on a mountain, verily, thou wouldst have seen it humble itself and cleave asunder for fear of Allah. Such are the similitudes which We propound to men that they may reflect. (59: 21)
2- Most of men approached with prejudices, glasses of horse and in a deviation. However If they had not approached with prejudice, bigotry and idea obsession. they would have understood Islam. Some of men understand completely way of life is a great problem. This idea is not valid for Islam. This idea is a conjecture and fictitious. Islam presents Divine Laws that guide all aspects of life by distinguishing right from wrong."
3- Deeds of hypocrites who are the one of the greatest enemy of Islam.
4- Most of men confuses with Muslim and Islam. Islam is excellent. There is no fault in Islam. Muslim is a Human being. The Human being can mistake. Islam doesn't want to commit a sin, make a mistake. Mistakes, crimes, sins never attribute Islam. There is no a community of representation in Islam. Communities never represent Islam. Muslims only serve Allah with utmost sincerity.
5- Muslims exactly did not submit Islam with a great sincerity. Most of governments usually did not govern according to Islam. Some Non-Muslim president want to control Muslims and make Muslims in slave for destroying Islam with their all powers. Some imperialist president, missionaries and Zionists exploit for own self benefits wealthes of the countries that Muslims especially lived.
6-The effect of Islam had not showed in Europe in spite of paths of tasawwuf (Sufism, mysticism). Tasawwuf is a false way and exlectic structure. This is Bid'ah (innovation) related to belief. Tasawwuf is not existing in Islam. Islam is not tasawwuf. Muslim belive Islam and not believe Tasawwuf. Islam is never been synthesized with any philosophy and any ideology. Islam rejected all ideologies.
