Human impact:

Good:

Tourism brings a positive impact to the ecosystem. Money from tourism not only brings fund to maintain the reserve but also raises awareness from the government and African communities to conserve the savanna because they can only attract tourism by maintaining the natural landscape and wildlife. Since the 1920s, the government has made laws to protect the Serengeti and later established this area as a National Park in 1951.

 Bad:

Human activities generate air pollution as they produce smoke and exhaust fumes. This releases CO2 into the air, making it increasingly harder to the animals to breathe. It also increases the temperature of biome, turning the savanna into a desert-like biome which many plants and animals are not adapted to.

Furthermore, the introduction of large factories with low regulation creates many chemical wastes that leek into the water system. Water is crucial to the survival of animal and plants. This will disrupt the balance of the ecosystem.

Ugly:

Humans have damaged the ecosystem as they settled in. When Europeans first settled in Africa, the animal population has disappeared by 1000s with every 100 increase in the human population. Humans have mined salt, coal and oil wells from the savanna. Humans have been transforming the natural landscape into agricultural land and for cattle raising. The popular agriculture practice is monoculture cropping which exhausts the soil of the Savanna. Large areas of the savanna in the South Africa have to been used for soybean cultivation. Over glazing has taken not only taken territory from wild animals but also depleted the land of water and grass for indigenous animals to feed on. 

 

Another human practice that harms the ecosystem severely is hunting. This has driven many animal species to become extinct or endangered. Many mega faunas and large carnivores have been hunted ceaselessly for meat, fur and special animals parts and sold into black markets. 40,000 animal are killed annually illegally in the park. This practice has harmed the ecological balance of the African Savanna greatly through killing key native animals. When a critical member of the ecosystem disappears and no other animal can fill its niches, the ecosystem will change and impact the remaining animal and plants negatively.
