Some Central Valley farmers are concerned about the possibility of losing some of their workforce, due to immigration policies proposed by President Trump.

Researchers at UC Davis said about 70% of all farm workers are living in the U.S. illegally.

Farm owners told the New York Times they’re worried the new immigration policies would destroy the workforce.

California agriculture is a $35 billion a year industry.

The Times said that figure could be cut drastically if undocumented immigrants are deported.
