Danh ngôn của Dennis Weaver (Sứ mệnh: 4)

When we realize we can make a buck cleaning up the environment, it will be done!
We don't have to sacrifice a strong economy for a healthy environment.
Practically every environmental problem we have can be traced to our addiction to fossil fuels, primarily oil.
If we had a hydrogen economy worldwide, every nation on earth could create its own energy source to support its economy, and the threat of war over diminishing resources would just evaporate.
