What would happen if African lions went extinct? Removing one species can weaken a habitat, but if a keystone species is removed, an entire ecosystem could collapse. If large predators such as lions disappeared, herd populations would balloon, and grazers would eat up the grass. The savanna would become a sandy desert.
Why are lions important to Africa? Lions are a keystone species. They are important predators – the only wild animals in Africa big enough to bring down big herbivores like elephants and giraffes. If herbivore populations are left unchecked there is less food available for all animal populations – including people.
What would happen if lions died out? Without lions, the ecological balance of our African savannas would be severely altered. Lions provide for all the scavengers like hyena, jackal, and vultures who eat the lions’ leftovers. So if lions are doing well, then the entire ecosystem is also doing well.
