The African savannah animals would be much more numerous and would occur in more places on earth if people were not there.
Large mammals live mainly in the national parks of Africa, but it doesn't have to be that way.
A globe without people would largely look like the African national parks with their rich animal life.
This is the conclusion of a study in which scientists from Aarhus University in Denmark simulated for the first time how mammals would have been distributed around the world if man had not existed.
The large mammals would, according to the researchers, probably spread throughout almost the entire world. North and South America in particular had a much richer animal life.
People spread at the expense of animals
The scientists' calculations show that for example, 45 species of large mammals would have lived in South America, and not just five, as is currently the case.
Only in Africa are so many species of large mammals, including elephants, hippos and rhinos.
The cause is that Africa is the only place on earth where humans have not eradicated the most large animals.
Africa is the last sanctuary for mammals
A new study shows that the large mammals in Africa could thrive farther north. The research focuses on the number of species of at least 45 kilos.
- In a world without people, there would be more large animals in Texas, US, than in the Serengeti National Park in Tanzania. South America would not have five major mammalian species, but 45.
- The real world map shows that only Africa today has a certain species richness. Without humans, elephants and rhinos could also have lived in the Netherlands and Belgium.
