Why are humans the top predators?

“Humans are perhaps unique among apex predators in their ability to influence ecosystems through simultaneously directly reducing large carnivore mesopredator and herbivore populations and by impacting their behaviour by creating a landscape of fear for all three trophic levels ” writes Dorresteijn et al.
