They just eat vegetable, fruits or beans which replace meat or fish. This shows that humans are no longer dependent on animals as they were in the past.
On the other hand, animals are still important in several aspects of modern life. In many developing countries, food that made from animals remains an important source of nutrition because it is cheap and easy to access.
