Serengetti, the Great Plains.
The scorching sun was burning the earth. Under the blue sky, a huge horned horse team was moving north.
Every year, from July to September, it was the transition between the rainy and dry seasons of the East African grasslands.
The rainy season in Serengetti had ended, and the rain area moved North. The rainfall decreased, and the dry season came. As a result, the Serengetti Plains gradually became a wasteland, and herbivores, including wildebeests, were facing a growing crisis of survival.
At the same time, the massemala Nature Reserve in northern Kenya was in the middle of a continuous rainy season, making it the "Garden of Eden" of the entire East African grassland with plenty of water and grass.
