Nature → Introduction
Nature itself could be a major threat to our survival. Of major significance at present is climate change. Is our natural weather getting warmer, wetter (or perhaps colder) and if so, what effect might these changes have both globally and here in the UK. If our climate is changing, how severe will this change be, and how rapidly might this happen?
There are also other natural events that might also impinge on our future survival. A major volcanic eruption that could black out the sky and pluge us into a prolonged "nuclear" winter. Perhaps a major earthquake and tsunami. How any of these events might occur and how they might effect our survival, needs some consideration.
