Dairyman Albert Straus was honored this week by the Board of Supervisors for his receipt of the annual Friend of the Farm Bureau award. Mr. Straus, founder of Straus Family Creamery, has been a leader and innovator in his field. He said the greatest threat to agriculture in Marin is the potential loss of the seashore’s historic ranches and dairies, whose efforts to incorporate carbon sequestration practices could also be a “critical step in the urgent fight against climate change.”   David Briggs
