If you stop and you think about everything we hold of value on this planet, metal, minerals, energy, real estate, the things that nations fight wars over. These things are in near infinite quantities out there.

If you believe that the developing world deserves the same standards of living that we do in the developed world, then to achieve that, they need resources. They need the metals and the minerals to build the industries and the buildings and so forth, and the energy.

Stuff goes wrong. Expect it, learn from it, fix it. That's how remarkable happens.
