Technology depends on rare earth minerals, but their extraction can harm our planet. Asteroids offer a plentiful source of valuable elements. In the future, mankind will go to the asteroid belt between Mars and Jupiter to mine for the vast wealth that is within the...

Understanding the complexities of problems is the sine qua non to pinpointing solutions.
Exercise: Break students into groups and ask each group to buy a tonne of carbon and then explain how they have contributed to the fight against global warming and why it is not enough.
