Final answer:
The failure of the agricultural revolution was marked by the lack of technological advancements in farming, starvation and malnutrition among peasants, and the negative impacts of the Green Revolution.
Step-by-step explanation:
One issue with the failure of the agricultural revolution is the lack of improvement in farming technology. Farmers had little incentive to increase productivity as they had to turn over most of their harvest for subsistence. Additionally, the educated population, who could have contributed new technology, lived in the capital and had no farming experience. Another problem was that many peasants suffered from malnutrition and starvation, with some resorting to cannibalism. Cash crops also failed, resulting in increased poverty. On the other hand, it's important to note that the Green Revolution, while successful in increasing food production, has also been criticized for bringing capital-intensive farming techniques that widened social inequality and led to expanding farmer debt.
