What do historians say are the drawbacks to complex civilizations and agriculture

Patriarchy, inequality, war, famine

Explanation:

Some of the drawbacks of civilization and agriculture, according to historians, are patriarchy, inequality, war and famine. Patriarchy has been a feature of many different civilizations all over the world. As men tend to be physically stronger and do not deal with the difficulties of pregnancy, they have often been able to achieve power and status more easily than women. This has led to many societies becoming patriarchal, often to the detriment of women.

Another problem is that of inequality. Large social groups usually require a strict organization in order to run smoothly. This has led to the development of social hierarchies, which have an enormous impact on how people live, usually leading to the existence of a "poor" class of people.

War has taken place among civilizations for many different reasons, such as competition over resources or status. Finally, famine has often taken place when civilizations are very large and agriculture is irregular.
