The "Al Gore" school of business

1) Find an appropriate apocalypse-mongering theory. It shouldn't be hard: Science is on a global decline.
2) Cook-up data to prove your point. Hide things that contradict your conclusions. Bash and discredit those that are not part of your conspiracy and will not buy it.
3) Make significant investment in technology which will "solve the problem". That way, when your theory establishes itself as mainstream, you'll be years ahead of everyone.
4) Instill fear into the public while presenting your theory. Throw in some cute animals dying. Win prizes for your efforts and then wield them as if you were born with them. Hold a free concert, preferably featuring Bono. Make a movie.
5) Organize international conferences to "warn the world". Treat your opponents as crazies, unconcerned with the future of the planet, their own children and those cute animals dying.
6) Use your "concern" as a way to distract people away from the real cruelty in the planet.
7) Profit from the "scientific agreement" and the fear in the public to pass legislation that makes it mandatory to turn to your "problem-fixing" technology.
8) Rake in the money. Go ahead: buy an SUV with it. It won't hurt anyone.
9) If your conspiracy ever gets discovered, disregard the exposé as "taken out of context" or just plainly ignore it.
