Humans have altered Earth so much that scientists say a new epoch in the planet's geologic history has begun. Say goodbye to the 10,000-year-old Holocene Epoch and hello to the Anthropocene. Among the major changes heralding this two-century-old man-made epoch: Vastly altered sediment erosion and deposition patterns. Major disturbances to the carbon cycle and global temperature. Wholesale changes in biology, from altered flowering times to new migration patterns. Acidification of the ocean, which threatens tiny marine life that forms the bottom of the food chain. The idea, first suggested in 2000 by Nobel Prize-winning chemist Paul Crutzen, has gained steam with two new scientific papers that call for official recognition of the shift. Complete Article

Complete ArticleWhen I read this article...the first thing that popped into my mind was that we were using all our natural resources or destroying them in our advancements....then the quote from Jurassic Park came to mind "Life always finds a way.." Some living things live in cycles...and with the earth slowing dying...it has to have some kind of natural defense I would think....
