something about drought that always scares me, seeing grass scorched and brown, and lake beds drying up...........scary, like the earth is dying or something........but then again where there was once deserts, there is now ocean, where there was once ocean, threre is now deserts............river s form, rivers dry up, so goes the cyclical cadence of nature.......global climate is constantly in a state of flux, nothing says that the temperatures wh have had in the past 50 years, are the optimal temps for our planet........
