The older I get I try to live a more enviromentally friendly exsistance - recycling, solar energy, walking and cycling instead of taking the car. However it is debatable what use our survival skills might have if we don't have an ozone layer to protect us or a sustainable biosphere around us.
As someone once said - it never rains, it pours.
