Bankruptcies do happen but we do not have to fear every time we invest in banks because the governments and the good people out there are willing to help. In most cases, even if they do happen, we will get back what we deserve. As I said, global warming is an issue since the late eighties.
Why worry about it and not concentrate on positive things around us for instance, a mug of Starbucks coffee, a bouquet of roses from your latest crush or to and fro rides on a swing at the nearest local park? So someday there will be a shortage of natural resources.
