It's theory based on a swiss professor, who has become from somebody who most scientists would laugh about to somebody who they take now extremely serious.
I'll try to get you guys some internet reading material since this is a extremely interesting read.
The Theory goes as follows:
Swarm animals as in Bees, locus, or other insects will be the dominant force on this planet and eventually push us of the food pyramid for good.
Why?
In a nutshell: Because swarm animals have no sense of self preservation and "think" mostly for the "swarm" not for themself, take for instance a swarm of ants trying to cross a small stream, 20.000 or so will wander happily to their death forming a bridge for the rest to cross the river in relative safety.
Take a zebra for the difference, even them life in herds or swarms, but being a mammal, every animal is looking out for their own interest when it comes down to survival.
The other thing is that specific animals who have literally no intelligence in a singular form, form a strange form of intelligence when counted by the Millions.
Experiments and tests have been done on bees, ants and so forth to back this up.
Don't you guys think this is interesting?
