Environmental issues......man-assissted global warming, clean water, air pollution, clean energy.....
Nothing else matters if we cannot breathe the air or drink the water. We are fools to believe anything has greater importance than this. We steadfastly ignore the evidence of how this us already affecting us.....from the famine in the Sudan to the impact on our own maple syrup industry. Global warming has become a recurrent topic in even our National Security Briefings due to it's impact world-wide.
We need to curb population growth and face the fact that the Western world's current lifestyle is unsustainable for the long run. That we may need to drive our cars less, wear sweaters more, eat some bruised fruit, practice some self-control. We need to realize that we cannot do what we please without consequence.
When I was in school we were taught about homeostasis. When I asked the teacher if mankind would ever reach homeostasis she said no, that mankind was smart enough to see it approaching and alter our behaviours. When food is short, wolves and other 'dumb animals' don't breed. I wonder who really is the smarter...them or us?
