How did peasants contribute to the decline of Han China?
klemol [59]

The correct answer is crushed by taxes and debt, desperate peasants revolted

In the early years of the second century AD, the Han Dynasty declined. Peasant rebellions and rivalries in the Chinese court contributed to the fall. Even the public procurement system did not function properly and honestly: Chinese officials began to be chosen for public office because of their personal influence rather than their knowledge and intellect.

In the year 220 AD, the Han empire was fragmented into three kingdoms. Constant guerrillas have caused serious problems for China. This period of Chinese history is called the Age of Disunity, which lasted until 589 AD.

krok68 [10]

Answer:

Wind turbines & solar panels that cost less to build.

Explanation:

First of all, we already have crops the require less pesticide protection, their called GMOs (genetically modified foods). Second, burning power planets or fossil fuels, is highly toxic to the atmosphere and creates a negative impact on the environment. Moreover, I do suppose long lasting batteries would be cool and easier to use, but I still don't think they would have a big impact to humanity. Lastly, there are about 12.3 million American homes getting their energy from solar panels, and solar panels are a reliable energy resource, and doesn't cause any harm to the environment. So clearly, solar panels and wind turbines that cost less to build would have a huge impact on society.
