At different times, about 7,000 plants and hundreds of animals were used as food by humans. The loss of species will reduce the diversity of food and make humans rely on only a few major foods, thus breaking the balanced diet structure of people In addition, with forests, the loss of species in the field can lead to an increase in certain pathogens, which are the culprits of disease in organisms. Some of the animals, plants and microorganisms most likely to become extinct are actually "buffers" for the spread of infectious diseases. Areas, they bear many diseases before they become infected. The following statements are inconsistent with the original:. ['Endemic species can buffer the spread of infectious diseases.', 'Loss of biodiversity affects human health.', 'Loss of species threatens human food safety.', 'The delicate relationship between species diversity and disease infection.']
