“Restore the Delta is such an important part of continuing Agriculture in Northern California. The products grown in this area are shipped to all parts of the world. From Pears to Wine Grapes, the farmers in our region help to feed the world. It is critical that as a state we distribute our resources in an equitable manner- especially water, and that does not mean subsidizing or sustaining one region at the expense or complete detriment of another. We need farms in California. We need Agriculture to survive.”
