One thousand years ago, less than 4 percent of habitable land was used for agriculture. Today, approximately 50 percent is used for agriculture. Which statement best explains why this large change occurred?(1 point)
Responses

Humans developed new agricultural practices which allowed the expansion of agriculture.

As human population grows, more food is produced, causing soil quality to decline, so more land is needed to grow the same amount of crops.

The human population increased rapidly, which caused a subsequent increase in the demand for food.

Most humans live in urban areas, so rural areas are heavily developed to provide food for those densely populated urban areas.
