It sits in the background as we marvel about the diversity of organisms we see around us today; about how some chemicals in a warm pond started to replicate billions of years ago and evolved, slowly, into trilobites, dinosaurs, trees, snails, grass, monkeys, mushrooms and humans. That secret is death. 5-billion-year history of life on Earth, of the 4 billion species that are thought to have ever existed, 99 percent are extinct. On our planet, extinction is the norm. Throughout history, plants and animals have come and gone as the climate and the environment have changed around them.
Setting a relatively high bar for what he counted as a mass extinction, in other words where more than 75 percent of all species per group of life form were lost, Barnosky calculated that the Earth would reach its next extreme, the sixth mass extinction, in just a few centuries. “How many more years would it take for current extinction rates to produce species losses equivalent to Big Five magnitudes? 4 years for mammals),” he wrote. The predicted rapid rise in the Earth’s temperature due to man-made climate change could halve the number of species on the planet.
Dust from a radiological weapon would remain trapped for extended periods in cracks and crevices on the surfaces of buildings, sidewalks and streets, and some would have been swept into the interiors of buildings,” said Levi and Kelly. “Certain materials that could be used in a radiological attack, such as cesium-137, chemically bind to glass, concrete and asphalt. ” Getting hold of radiological material would not be difficult today. In hospitals, radium and caesium are used as sources of radiation in cancer treatments.
