Via London’s Daily Mail, guess who has an opinion about how you should live your life?

Heather Mills launched another extraordinary tirade in public today, urging people to drink rat’s milk to save the planet.

During the rant at Speakers’ Corner in Hyde Park, the former model said eating meat and dairy was destroying the earth …

Heather suggested there were better alternatives to cow’s milk lattes: “Why don’t we drink rat’s milk or cat’s milk or dog’s milk?”

Mills arrived for her milk-is-killing-the-planet spiel in a petrol-guzzling SUV, naturally. Not to mention posing for pictures so she can be in the newspapers, which are printed on something called paper. Which doesn’t exactly grow on trees, sweetie! Wait a minute. Well… you know what I mean. But before you dismiss Heather as some kind of tone-deaf nut, keep in mind that she’s something of an expert on alternative sources of sustenance. After all, for the last five years she’s survived — thrived! — by milking a single Beatle. Update: Mills reportedly left her SUV’s engine running while agitating against climate change. You can’t make this stuff up.
