The wild maintained

The lions in Akagera in Eastern Rwanda are descendants of cubs gifted by the government of South Africa.

Due to Rwandan people migrating back to their homeland along with their cattle, the population of lions grew exponentially. The lions enjoyed the buffet of lazy cows. The villagers did not enjoy this, and started killing the lions, to the point of completely decimating their population.

Nature has its own formula. And we, humans, have a few of our own.
