A liver fluke most likely can be killed in the body with a frequency. Yet without changing the environment that attracted the liver fluke and allowed it to live, that simply is vacating room for new liver fluke tenants. Instead of attacking the liver fluke directly, it is more effective in the long run to change the environment. Anti-bioenergy is the lack of life supporting energy. For instance, fleas host a certain tapeworm that must develop in the flea for the tapeworm to infect an animal who bites and swallows the host flea.
Termites eat away rotting wood fibers.
Basically, any creature that takes without giving anything good in return is anti-bioenergy controlled. In comparison, earthworms digest compost and help fertilize the earth, giving a benefit. When a plant is distressed it begins to loose bioenergy and allowing higher levels anti-bioenergy. As they begin feasting, the plant becomes more distressed and bioenergy is drained in the fight. This goes on until there is no plant left because anything that has an anti-bioenergy nature also has an insatiable appetite.
