The wet/dry climate is what controls the structure there. Scientists worry that if global warming continues, that will be a huge problem for what lives in this biome. The animals and plants would not be able to survive with more heat and less rain. Some of them would be able to adapt, but eventually they would all die off. Tourism is a huge activity in the savanna biome, especially in Africa. However, vehicles, humans, and their pollutants can be very hazardous to both the plants and animals. There are also guided hunts in the savanna biome of Africa. Many of them are done illegally. Many of these animals are very low in numbers and by hunting them it jeopardizes the future of the biome. There has to be a balance between predators and animals. Lions are top predators and when they're being hunted there can end up being too many deer, zebra, and other grass eating animals. That can result in making it harder for the grasses to be replenished. Which can lead to animals starving to death.
