The monsoon flood of July 2010 left 2,000 casualties in Sindh region, Pakistan, and forced more than 20 million people out from their homes. One-fifth of the country’s total area was under water (the equivalent to the whole size of England). Spiders could not find any other way to survive, but to climb up on trees. The extreme concentration of arachnids at these points turned those trees into completely cocooned structures, with endlessly overlapping spider webs.
Nearly 1,000ft below the Chihuahua Desert in Mexico, a gigantic cave was discovered by two brothers drilling in the Naica lead and silver mine in 2007-2008. It was an eerie sight. Obelisks shaped crystals up to 37 feet (11 meter) in length and the equivalent height of six men jutted out from the damp rock walls, and there were hundreds of blade-sharp crystals.
