Pálido punto azul

La imagen de al lado es para mí la visión más nítida que jamás haya tenido de lo que es en realidad el planeta Tierra. Sonreíd, ese puntito azul pálido que se distingue en el centro somos nosotros, todos. Nos sacó la foto la sonda Voyager1 después de situarse más allá de la órbita de Plutón tras un viaje de 13 años. Era el 14 de febrero de 1990. San Valentín.

Carl Sagan (¡cómo no!) se encargó de recordarnos que
Eso es nosotros. Sobre él vivieron sus vidas todo lo que amas, todo lo que sabes, todo aquello de lo que has oido hablar, cada ser humano que existió. Toda nuestra alegría y sufrimiento, miles de religiones, ideologías y doctrinas económicas, cada cazador y recolector, cada héroe y cobarde, cada creador y destructor de la civilización, cada rey y campesino, cada pareja enamorada, cada madre y padre, hijo esperanzado, inventor y explorador, cada maestro de moral, cada político corrupto, cada "superestrella", cada "líder supremo", cada santo y pecador en la historia de nuestra especie vivió ahí,.. en una mota de polvo suspendida en un haz de luz...
El calentamiento global, la escasez de agua potable, la contaminación, el peligro nuclear, el agujero de la capa de ozono pueden hacer que ese puntito deje de verse. Entonces, sólo quedarían las sondas Voyager como testimonio de que una vez existió la especie humana.

No tenemos alternativa, debemos parar el deterioro del planeta. No es ecologismo. No es política. Se trata de la lógica aplicada al más primario de los instintos: la supervivencia.

Nadie puede demostrar con fórmulas matemáticas que esto se va a acabar, ni los que estudiastéis física.

Hombre, decir que nadie puede demostrarlo es mucho decir. ¡¡Rbr que eres de ciencias por dios!! Sin entrar en detalles ahí va la ecuación del deterioro de la capa de ozono: Cl + 03 ––> Cl 0 + 02
De todas formas, para asegurarnos sin usar fórmulas matemáticas podemos seguir igual, a ver que pasa. ¿No? Podríamos apostar, pero ¿si se acaba quien gana la apuesta? A no ser que venga una especie de capitán Spock a sacarnos de aquí de momento no tenemos otro sitio en el universo al que ir.

Todo lo que comienza se acaba. Esto habr� comenzado alguna vez, as� que se acabar�. Lo que pasa es que as�, siendo tan peque�itos e insignificantes.. pues parece en realidad, que no tiene importancia. Y eso no es verdad, s� que importa. Yo no s� si estoy muy de acuerdo en esto de vernos desde tan lejos tan lejos tan lejos.. porque entonces parece qeu es efectivamente as�, que aqu� es irrelevante lo que suceda, incluso si nos calentamos mucho mucho y nos vamos a tomar vientos. Lo que es importante es ver las cosas de cerquita, a trav�s de la ventana de la cocina de todo el mundo.. ah� es donde nos damos cuenta de lo importantes que somos cada uno. No?

Creo que la Vida no puede ser eliminada por el hombre , lo considero imposible (cuestión de fe); ahora bien, deberiamos profundizar en nuestra fragilidad de mamíferos. Vivimos en un momento sorprendente ya que somos conscientes de que vamos por mal camino pero al mismo tiempo este `pesimismo social en lo ecológico no se convierte en acciones efectivas...estamos piraos?

Qué se podemos acabar co mundo? Non teño ningunha dúbida: non hai máis que mirar todo aquilo co que xa acabamos: especies animais e vexetais de todo tipo, auga, ar (ozono), etc, etc.. Non teño ningunha dúbida de que se non poñemos freo a isto, é perfectamente posible, e ninguén gañaria a aposta. Nós vémonos de cerca, importantes, pero ven ben esta visión desde lonxe, para darnos conta de que o que para nós é tan importante, é bastante insignificante, e seguramente moi fráxil, moi vulnerable... como a vida mesma.E o peor é que pasa como con tantas outras cousas, a carretera,os riscos que asumes en calquera labor cotiá: tí podes poñer todo o posible para evitar o desastre, pero non depende só de tí; desde que o poder de destrucción nuclear está en manos ao fin de simples individuos, non necesariamente dotados de sensatez suficiente, verdade?, (e refíreme tanto a posibeis "gobernates" como a posibeis "terroristas"), só podemos esperar ter a sorte de que algúnha mente sensata controle sempre á insensata.
Xa che dixen Guilherme que está moi ben a túa blog?

James Hansen, el principal experto en cambio climático de la NASA, denuncia que el gobierno USA intenta silenciar la realidad del cambio climático (y de paso a él).Resulta curioso observar como los gobiernos secuestran el debate mientras las noticias sobre la transformación del clima son presentadas como cualquier otra cosa más en los principales medios de comunicación; se está dosificando convenientemente la realidad y nosotros lo estamos aceptando como algo inevitable,es mi caso. El sistema es esencialmente materialista y da muestras todos los días de lo amortizables que somos las personas, incluso en las regiones donde no se pasa hambre.

Hello,

I'm seeking help for the kids of Haiti.

I'm here for a non-profit haiti organization that is devoted to giving time to
creating an oppurunity for the kids in haiti. If anyone here wants to help then do so here:

[url=http://universallearningcentre.org]Donate to Haiti[/url] or Help Haiti

They provide kids in Haiti a positive learning environment.

Yes, they're legitimate.

It would be great if you could help

Long time lurker, thought I would say hello! I really dont post much but thanks for the good times I have here. Love this place..

When I was hurt in that car accident my life would be changed forever. Unfortunately that driver had no car insurance and I was going to be in pain for ever.

This was not time for me to start and guess what to do. I had to find a good personal injury attorney to help me get what I needed. After all, my family was counting on me.

How bad was it? I has bedridden for 7 months, I had to have constant care and my medical bills went through the roof!

Luckily, I found a good referral site to help me.

I will post more later this period to tell you more about what I have been going through.
