The taming of wild animals has long been known to the human mind. It is much more difficult to create conditions suitable for life for them. What needs to be done to make every lion and every monkey feel at home? Create a huge natural complex for their existence. Think about their food and movement.
They should have enough space to coexist. Remember that predators cannot be placed in the same space as herbivores. Otherwise, the game will turn into real chaos. The new land for wild creatures should become their paradise.
