Many humans would agree with this sentiment. Instead, attacks were more common at sites with many males and high population densities. Large predators need a lot of space, and in a human-dominated world, they need to be able to live alongside humans without conflict. They live in fusion-fission societies where the community breaks up into small subgroups (fission) that travel separately and sometimes come together (fusion).
