All good info but I'm going to 'cherry pick' a QUOTE: That brings us the more unpleasant concern, which is the planet earth has too many people in demand of dwindling resources. Looking forward, there are not enough resources, oil and energy to keep everyone on earth comfortable within their current or anticipated standard of living.
A couple of things I've heard lately that brings me down to Earth;
1.The US has 100,000 workers added to the workforce every month. That's after all the retirements, deaths, ect. Every month the number of working people in this country goes up at least 100,000. To me, that hits home and is sobering.
2.The Earth doesn't produce enough 'healthy food' to support it's population. If we all decided to eat the prescribed amount of fruit and vegies there wouldn't be nearly enough..... And if we all started to eat right that number above (100,000 new workers every month) would double.
