Determinants of Our Future--Your Ideas?

I’d like your thoughts on the most important issues shaping our future, for my book on global youth viewpoints. Here’s a start:

Inequality in poverty and wealth, power, age distribution, and gender.
The trillions spent on war.

Power shifts are underway: Predictions are the BRIC nations will be the future economic superpowers

The bottom line for our future is the environment.

Thanks for your thoughts, Gayle
