What environmental change impacted the Agricultural Revolution?

moving to forests or undisturbed land

Explanation:

Farming-based methods have strengthened/got worse continuously ever since the Industrial Revolution, and even more so since the "green revolution" in the middle at least 20 years of the 20th century. At each stage, inventions of new things in farming ways of doing things brought about huge increases in crop yields by area of land where crops can grow well. This huge/extreme rise in food production has sustained a worldwide population that has quadrupled in size over the span of one century. As the people continues to grow, so too has the amount of space dedicated to feeding it. According to World Bank figures, in 2016, more than 700 million hectares (1.7 billion (areas of land about 200 feet X 220 feet)) were loyal to/were dedicated to growing corn, wheat, rice, and other staple cereal grains--nearly half of all (helped to grow) land on the planet.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.        

the answer would be a)henry grady because he came up with the term "new south"
