We humans, through the negligence that grows out of our denial, are destroying our planet. We spread pollution through our industry, our overpopulation, our fertilizers, and our insecticides. We wreak ecological havoc through our unsustainable farming, our logging, and our exploitation of the world’s other natural resources. We are making our home unlivable not only for ourselves but for the millions of other animal and plant species with whom we share it.
SICK HUH?
Scientists are exploiting one of Einstein's predictions to find Earth-like planets around other stars–planets that might even support Earth-like life.

WHY: To determine whether we are alone in the universe. We're much more likely to find life on a rocky planet than on a gas giant like Jupiter–and if the human race needs to find a new home in the future, rocky exosolar planets will probably be our destination. Also, some scientists theorize that small, solid planets outnumber gas giants (10:1 is a conservative estimate), but until now they couldn't test that hypothesis.
WHERE: All across the globe. A loose network of astronomers point their telescopes at the center of our galaxy, where they can see many stars at once. Because gravitational-microlensing events happen over the course of 10 to 40 days, research teams on different continents record data as dawn–and the end of viable observation time–approaches for their cohorts.
WHO: Two international teams of scientists, based in Chile and New Zealand and assisted by hundreds of volunteer astronomers, look for microlensing events across huge swaths of sky. They alert each other of probable events by Web and e-mail.
FAQs
How many planets have been found?
Around 200. Most have been spotted by looking for wobbles in a star's motion that are caused by the gravitational attraction of a planet. But since this method preferentially finds huge planets that orbit close to their suns, it's turned up mostly "hot Jupiters."

Are any of them earth-like?
Not yet. Microlensing has found four small, solid planets. But they are too far away from their suns–and thus too cold–to support life. (The Scorpio planet is estimated to be a bitter 364 degrees.

El agua contaminada, una higiene y servicios de saneamientos deficientes y la contaminación del aire, incluso la causada por combustibles domésticos "sucios" utilizados para cocinar, a los que se les suman el humo del tabaco y los productos químicos peligrosos; se encuentran entre las principales causas de las enfermedades mortales para los niños.

Otra causa habitual de muerte infantil son las intoxicaciones no intencionadas, particularmente en países pobres por el uso de plaguicidas, el monóxido de carbono producido por aparatos de combustión deficientes o el queroseno empleado como combustible doméstico. Sin embargo, en países como Estados Unidos, las intoxicaciones también constituyen una causa alarmante de muerte de niños menores de seis años, principalmente por ingestión de drogas, antidepresivos, analgésicos y productos de limpieza.
También es para destacar los miles de niños palestinos que sufrieron el efecto directo del conflicto y las consecuencias que estos trajeron como por ejemplo: La destrucción de la destrucción de la infraestructura básica y la falta de agua potable o comida.

Pero la contaminación no solo afecta al ser humano sino que produce grandes desastres a nivel fauna o flora del planeta como también afecta gravemente los paisajes de las diversas zonas.
