If someone could actually prove scientifically that there is such a thing as a supernatural force, it would be one of the greatest discoveries in the history of science. So the notion that somehow scientists are resisting it is ludicrous.

The work on ants has profoundly affected the way I think about humans.

The global conservation organisations are doing everything they can on modest budgets. They essentially promote setting aside reserves and parks around the world.
