But any feeling of emptiness is an illusion – the plains of our planet support the greatest gatherings of wildlife on Earth. And at the heart of all that happens here is a single living thing – grass. Grassland plains encompass a quarter of the land on earth and bear witness to some of the most dramatic wildlife stories on our planet... and in Africa, the Great Plains are wild and ever changing.
