Anomalous gravitational field (AGF) is the most important geophysical factor of the habitats of organisms, including humans. The results obtained during research allow us to assess the impact of AGF of different strength on the organisms. It was found that a negative AGF produces a negative impact on the organisms. The higher intensity of the positive field on the Earth is, the higher birth rate and natural population growth and the lower mortality rates are. Orientation of the society on development of the lands located in the positive AGF zones will allow us to rapidly change environmental conditions to minimize the loss of population
