AUDIENCE MEMBER: Hi, Mr. Buffett, Mr. Munger. My name is Vern Cushenbery and this question is on behalf of a group of investors that made the trip up today from Overland Park, Kansas. Given your interest in renewable energy and natural resources, I wonder if you’d be willing to share your thoughts on how a world of limited and depleting clean water supplies and declining food stocks affects your investment strategies and thinking on the future.
