Suppose you had trees on your property that served as a privacy barrier and provided shade for your home. Then imagine your eco-minded neighbor installs solar panels and demands you cut down your trees so sunlight can reach his panels.

You might think: It's my property! The problem is - your neighbor has the law backing him up, according to the April 7 "CBS Evening News." Sounds like a case of environmentalism gone wild, right?

"Richard Treanor lives across the fence, drives a hybrid car," CBS correspondent Ben Tracy said. "Ten years ago he planted these redwoods to provide privacy. Now they had his neighbor seeing red."

"He called us over to the fence one day and said ‘I am going to be installing solar panels and therefore you have to take your trees down,'" Treanor explained.

And thanks to California's 1978 Solar Shade Control Act, the trees had to go. Failure to comply is a criminal offense.
