Now that summer is here, you'll likely be slathering up with sunscreen.
Earth, it turns out, is doing the same, according to an encouraging study recently published by a team of scientists at NASA Goddard Space Flight Center and Goddard Earth Sciences Technology and Research at the Universities Space Research Association.
Earth has its own layer of sunscreen called the ozone layer, or ozone shield, which makes up part of the stratosphere and absorbs most of the sun's ultra-violet (UV) radiation. But it doesn't absorb all of the UV light, and what gets through can cause skin cancer and cataracts in humans as well as reproductive problems in fish, crabs, and frogs.
