FreeRice is a sister site of the world poverty site, Poverty.com.
FreeRice has two goals:
Provide English vocabulary to everyone for free.
Help end world hunger by providing rice to hungry people for free.
This is made possible by the sponsors who advertise on this site.
Whether you are CEO of a large American corporation or a street child in India, improving your vocabulary can improve your life. It is a great investment in yourself.
Perhaps even greater is the investment your donated rice makes in hungry human beings, enabling them to function and be productive. Somewhere in the world, a person is eating rice that you helped provide. Thank you.
Stephen Petranek reveals the question that occupies scientists at the end of the day. How might the world end? He lays out the challenges that face us in the drive to preserve the human race. Will we be wiped out by an asteroid? Eco-collapse? How about a particle accelerator gone wild?
Most interesting is the decrease in the earth’s magnetic field that has allowed in more radiation. If the magnetic field has decreased (more) strength by 5% this might partly account for the recent increasing of temperature?
In a sobering 3-minute talk, Dr. Dean Ornish tracks the dramatic spread of obesity, diabetes and cardiovascular disease around the globe — as people outside the US start to eat, live and die like Americans do. “This may be the first generation in which our kids live a shorter lifespan than we do,” Ornish says. The good news? These trends are preventable and even reversible through diet and exercise.
According to Dr. Ornish “Cardiovascular diseases kill more people each year than in the US. And worldwide than all other illnesses combined… Of these 95% are preventable and reversible.”
In this four-program series, string theory pioneer Michio Kaku goes on an extraordinary exploration of the world in search of time.
He discovers our sense of time passing and the clocks that drive our bodies. He reveals the forces of time that make and destroy us in a lifetime. He journeys to some of the Earth’s most spectacular geological sites to look for clues to the extraordinary depths of time at a planetary level. Finally, he takes us on a cosmic journey in search of the beginning (and the end) of time itself.
