I think that the world needs to seriously consider how it wishes to apportion various resources to the global population. That means a radical rethink of the current political system, or future generations may very well face a future of wars over dwindling resources, especially food, fresh water, and the remaining fossil fuels.
Even taking that into account though, I think the future is much brighter than it was say a decade or 2 ago with respect to the prospect of nuclear armageddon though, although there is still obviously a risk that some fruitloop with an agenda - almost certainly religiously inspired, going on modern history - might construct a dirty bomb or similar.
What will not help one jot is for everyone to sit on their backside and hope and pray for divine intervention.From what I have read and seen, most of the christian fundamentalists seem positively eager to experience the rapture -not a good mindset to approach proper stewardship, sharing and conservation of global resources - and you appear to have an equally rabid fanatical cohort of islamic terrorists who relish the opportunity of field testing their 72 virgins.
Fortunately, as global citizens, we can really on pragmatic self interest, increasingly civilised and more rational societies, and use of the scientific method to explore better or different ways of exploiting the world around us -hopefully a way that is better for the earth too.
If you wish to place your faith in god, thats fine, I guess - I prefer to place my confidence in mankind....
