    Living without an ozone layer

    If our ozone layer just up and vanished one day, what would be the consequences on Earth's surface? How much would the UV reaching us increase? How would day to day living be affected?

    Years I ago I created a website intended for use by writers wanting some real science with their SF writing. The link below goes to "Shining Star", a website about a nearby supernova blasting away the ozone layer and leaving Earth to die in the aftermath. Hope it is of some help. Many links are broken now, some science needs updating, but might be useful.

    "The ozone in the ozone layer absorbs 97-99% of all the ultraviolet light that passes into the stratosphere." (http://butane.chem.uiuc.edu/pshapley/GenChem2/A2/1.html), so the increase would be by a factor of 30 to 100.

    This would bring the UV levels to the point where water would dissociate and many organisms, especially microorganisms, on the surface would be killed quickly. Larger organisms would be killed in fairly short order.

    How do things fly? This explains it all.

    Actually they can't: "Heavier-than-air flying machines are impossible." - Lord Kelvin, president, Royal Society, 1895.
