he new science of ozone and UVB is not pretty. The ozone threat is not solved, scientists say. From Zürich, lead author Dr. William Ball says Earth’s ozone shield against harmful radiation continues to weaken – despite an improvement of big ozone holes over the Poles. Thinning ozone is right over where most people, animals and plants live. It’s possible our smog is the last protection.
But wait. Another study from University of California Berkeley says a weakened ozone shield 251 million years ago drove the mass extinction of forests, and all life that depended on them. Lead author Jeffrey Benca explains we underestimated the risk of significant harm from thinning ozone, and misunderstand the hidden process of mass extinction. All science from Radio Ecoshock.
