What Bill Gates Meant by: "Depopulation Through Vaccines!?"

Bill Gates says on the context of ways to stop the increase the number of population in order to reduce production OC2 Gaz, that vaccines along with other means will be used in order to depopulate the world by at least 10-15%.

Which means that up to 1 billion people should be wiped off the face of the earth.

No one would believe that Bill Gates WOULD mean that, especially in such respectable place like TED conferences.

But it seems that after the swine flu phobia, many people start question seriously the conspirationist theory of project of massive depopulation of the planet!
