Anthrozoology (also known as "humananimal studies") is the study of interaction between living things. It is a burgeoning interdisciplinary field that overlaps with a number of other disciplines, including anthropology, ethology, medicine, psychology, veterinary medicine and zoology. A major focus of anthrozoologic research is the quantifying of the positive effects of human-animal relationships on either party and the study of their interactions. It includes scholars from a diverse range of fields, including anthropology, sociology, biology, and philosophy.[n 7]

What does the field of anthrozoology overlap with?
Answer: number of other disciplines

In 2014, the city had an estimated population density of 27,858 people per square mile (10,756/km), rendering it the most densely populated of all municipalities housing over 100,000 residents in the United States; however, several small cities (of fewer than 100,000) in adjacent Hudson County, New Jersey are more dense overall, as per the 2000 Census. Geographically co-extensive with New York County, the borough of Manhattan's population density of 71,672 people per square mile (27,673/km) makes it the highest of any county in the United States and higher than the density of any individual American city.

How many people live in a square mile of New York City?
Answer: 27,858

This period is generally taken to coincide with a major shift in population from southern Mesopotamia toward the north. Ecologically, the agricultural productivity of the Sumerian lands was being compromised as a result of rising salinity. Soil salinity in this region had been long recognized as a major problem. Poorly drained irrigated soils, in an arid climate with high levels of evaporation, led to the buildup of dissolved salts in the soil, eventually reducing agricultural yields severely. During the Akkadian and Ur III phases, there was a shift from the cultivation of wheat to the more salt-tolerant barley, but this was insufficient, and during the period from 2100 BC to 1700 BC, it is estimated that the population in this area declined by nearly three fifths. This greatly upset the balance of power within the region, weakening the areas where Sumerian was spoken, and comparatively strengthening those where Akkadian was the major language. Henceforth Sumerian would remain only a literary and liturgical language, similar to the position occupied by Latin in medieval Europe.

Poorly drained irrigated soils in an arid climate with a good deal of evaporation is responsible for leaving what?
Answer:
dissolved salts
