Flying in Airplanes Exposes People To More Radiation Than Standing Next To a Nuclear Reactor (businessinsider.com)
Traveling the skies by jet lifts us far from the hustle and bustle of the world below. From a report: But many flyers don't know that soaring miles above Earth also takes us out of a vital protective cocoon -- and a little closer to a place where our cells can be pummeled by radiation from colliding stars, black holes, and more. You can't see these high-energy charged particles, but at any given moment, tens of thousands of them are soaring through space and slamming into Earth's atmosphere from all directions. Also called cosmic rays or cosmic ionizing radiation, the particles are the cores of atoms, such as iron and nickel, moving at nearly light-speed. They can travel for millions of years through space before randomly hitting Earth. These rays don't pose much of a risk to humans on Earth's surface, since the planet's atmosphere and magnetic field shield us from most of the threat.
Has its disadvantages.
I for one am looking forward to the day when live in organic wooden huts with a windmill to charge the cell phone.
We won't have to fly airplanes ever again. We will stop eating meat and feast upon acorns and nuts which we gather. On holidays we can celebrate with a feast of tofu burgers.
No more plastic shopping sacks. No more cars. No more hydro, nuclear, or coal. And there will be no more sexism or racism. The Negroes will cease their criminal activity and join in our tofu lifestyle.
It can happen. We can do it. Sí, se puede
