I figured out how to watch these videos quicker. I right click the video and choose "copy video URL" then I past it and watch it directly on Youtube and click settings - playback speed, select 2x speed, and turn on captions.
If farmers have to irrigate anything except for vegetables for human consumption then they should be growing a different crop. The underground water tables used for irrigation are in danger of being depleted. Good farmers don't run irrigation.
"In parts of the United States, sixty years of the profitable business of intensive farming using huge center-pivot irrigators has emptied parts of the Ogallala Aquifer (also known as the High Plains Aquifer). One of the world's largest aquifers, it covers an area of approximately 450,000 km2 (170,000 sq mi) in portions of the eight states of South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas, beneath the Great Plains in the United States. The total water extraction from center-pivot irrigation in the area is estimated to be about 5.42 million acre-feet of water per year."
"In 1950, irrigated cropland covered 100,000 hectares (250,000 acres). With the use of center-pivot irrigation, nearly 1.2 million hectares (3 million acres) of land were irrigated in Kansas alone. At some places, during maximum extraction, the water table dropped more than 1.5 m (5 ft) per year. In extreme cases, wells had to be greatly deepened to reach the steadily falling water table. In some places in the Texas Panhandle, the water table has been drained (dewatered). "Vast stretches of Texas farmland lying over the aquifer no longer support irrigation. In west-central Kansas, up to a fifth of the irrigated farmland along a 100-mile [160 km] swath of the aquifer has already gone dry." It would take hundreds to thousands of years of rainfall to replace the groundwater in the dried up aquifer."
