Hunting and Gathering avoided what downsides? (2 reasons)

Explanation:

Hunter-gatherer (H-G) diets tend to be diverse - both meat and vegetables - thus proving a nutritious diet most of the time. However, when foods is not available (e.g. a climate drought) hunter-gatherers often face starvation.

Another advantage is it tends to re-enforce what's called "pro-social" behaviour - in other words, people tend to get along pretty. Many H-G societies tend to be under 150 people and so everyone knows everyone else or is in fact related. H-G societies will often ostracize or expel individuals who are making trouble in the clan and everyone knows that this is a possibility, so they tend to not make too much trouble. In contrast, in big city states, there is more anonymity, people try to get away with more bad behaviour.
