What is the biggest problem facing our food supply today? Can we fix it? How?
well the big problem facing food right now is that the overpopulation that accurting around the world... with so many people giving birth and not enough food growing... in addition food takes long to grow and prepare.... we can fix it by limiting birth rates and limiting the amount of food to a healthy amount per day....;)

about your attitude towards trash and poisons. What has surprised you? have you resolved to do anything differently? If so why? If not why not?
well i think we should be more careful of what we throw in our trash because some trash can be poison.... for example computer, batteries and etc. you can go online to find a place that will take your computers and batteries.... you can also go online and find your closet recycling aera to you..... i recycle everything i can to help the earth be a better and cleaner place.... ;)

Which alternative energy do you think is best? Why?
I THINK SOLAR ENERGY IS THE BEST BECAUSE IT COMES FROM THE SUN AND THE EARTH RECEIVES A LOT OF ENERGY FROM THE SUN IN 20 DAYS ITS ALL STORED IN THE EARTH... AROUND 15 PRE-CENT OF THE ENERGY OF THE SUNLIGHT CAN BE USED TO PROUCE ELECTRICITY BY USING PHOTOVOLTAIC SOLAR TECHNOLOGY... THERE IS INDEPENDENCE FROM FUELS, FUMES AND OTHER HARMFUL THINGS.

REDUCE
REUSE
RECYCLE....
IF YOU LOVE OUR PLANET THEN TAKE CARE OF IT... THESE ARE SOME THINGS THAT YOU CAN DO TO MAKE A DIFFERENCE.....
REDUCE: you can reduce the use of water by taking 5 min. showers....
REUSE: you can reuse plastic bags, water bottles and other things....
RECYCLE: you can recycle a lot of things around you like cans, bottles, paper and a lot more.....
RETHINK: next time you want to throw something away think of all the things you can do with it....
Should countries like China be able to dictate how many kids families can have? Why or why not?
I DONT KNOW WHAT TO SAY IN WAY ITS GOOD BECAUSE, IF THERE IS MORE PEOPLE THERE CAN BE LESS FOOD GROWING , MORE POVERTY AROUND THE WORLD
AND DISEACES CAN SPREAD.... IN THE OTHER HAND IT WOULD BE NICE TO HAVE AS MANY CHILDREN AS YOU WHAT AS LONG AS YOU CAN TAKE CARE OF THEM.... WELL I GUESS EACH ONE HAS THERE UPS & DOWNS TOO IT ....

Which contraceptive method do you feel is most appropriate for your peers?
I THINK THAT PEOPLE SHOULD USE ANYTHING.... PEOPLE HAVE DIFFERENT OPPINIONS ON CONTRACEPTIVE METHODS LIKE BIRTH CONTROL , Calendar methods, AND CONDOMS.... ITS FINE AS LONG AS IT DOSENT HURT ANYONE AND KEEPS THEM SAFE....

Scientists discover a nearly Earth-sized planet

HATFIELD, England – In the search for Earth-like planets, astronomers zeroed in Tuesday on two places that look awfully familiar to home. One is close to the right size. The other is in the right place. European researchers said they not only found the smallest exoplanet ever, called Gliese 581 e, but realized that a neighboring planet discovered earlier, Gliese 581 d, was in the prime habitable zone for potential life.
"The Holy Grail of current exoplanet research is the detection of a rocky, Earth-like planet in the 'habitable zone,'" said Michel Mayor, an astrophysicist at Geneva University in Switzerland.
An American expert called the discovery of the tiny planet "extraordinary."
Gliese 581 e is only 1.9 times the size of Earth — while previous planets found outside our solar system are closer to the size of massive Jupiter, which NASA says could swallow more than 1,000 Earths.
Gliese 581 e sits close to the nearest star, making it too hot to support life. Still, Mayor said its discovery in a solar system 20 1/2 light years away from Earth is a "good example that we are progressing in the detection of Earth-like planets."
Scientists also discovered that the orbit of planet Gliese 581 d, which was found in 2007, was located within the "habitable zone" — a region around a sun-like star that would allow water to be liquid on the planet's surface, Mayor said.
He spoke at a news conference Tuesday at the University of Hertfordshire during the European Week of Astronomy and Space Science.
Gliese 581 d is probably too large to be made only of rocky material, fellow astronomer and team member Stephane Udry said, adding it was possible the planet had a "large and deep" ocean.
"It is the first serious 'water-world' candidate," Udry said.
Mayor's main planet-hunting competitor, Geoff Marcy of the University of California, Berkeley, praised the find of Gliese 581 e as "the most exciting discovery" so far of exoplanets — planets outside our solar system.
"This discovery is absolutely extraordinary," Marcy told The Associated Press by e-mail, calling the discoveries a significant step in the search for Earth-like planets.
While Gliese 581 e is too hot for life "it shows that nature makes such small planets, probably in large numbers," Marcy commented. "Surely the galaxy contains tens of billions of planets like the small, Earth-mass one announced here."
Nearly 350 planets have been found outside our solar system, but so far nearly every one of them was found to be extremely unlikely to harbor life.
Most were too close or too far from their sun, making them too hot or too cold for life. Others were too big and likely to be uninhabitable gas giants like Jupiter. Those that are too small are highly difficult to detect in the first place.
Both Gliese 581 d and Gliese 581 e are located in constellation Libra and orbit around Gliese 581.
Like other planets circling that star — scientists have discovered four so far — Gliese 581 e was found using the European Southern Observatory's telescope in La Silla, Chile.
The telescope has a special instrument which splits light to find wobbles in different wavelengths. Those wobbles can reveal the existence of other worlds.
"It is great work and shows the potential of this detection method," said Lisa Kaltenegger, an astronomer at the Harvard-Smithsonian Center for Astrophysics.

What natural disaster do you feel Southern Californias are least prepared for? What should we do?
EARTHQUAKES BECAUSE WE DONT REALLY GET THEM A LOT AND PEOPLE DONT REALLY THINK MUCH OF IT BECAUSE A BIG EARTHQUAKE HASNT HAPPENED YET... PEOPLE SHOULD ALWAYS BE PREPARED FOR ANY DISASTER NO MATTER WHAT THINGS COME WHEN YOU LEAST EXPECTED....

GLOBAL SUPERSTORM
Do you think a Global Superstorm has occurred before? Why or why not?
---> I DO THINK IT HAS OCCURRED BEFORE BECAUSE OF THINGS FOUND.... LIKE SKULLS OF HUMAN THE WAY THE SKULL WAS SHAPED FOR PEOPLE THAT LIVED IN COLD WHEATHER.... THERE IS OTHER THINGS FOUNDED ALL AROUNDS US....
