As we saw last week, Al Gore now has plenty of ideas when it comes to pickup lines to use on the ladies. Taking it a step further, PETA has sent the recently separated former vice president a letter urging him to go vegan — not only for the planet, but also as a way to rekindle his love life.

The group has long been on Gore's case to transition to an all-veg diet, to more closely align the man's personal eating habits with his environmental campaigning. Obviously, the group saw this latest rift in his personal life as an opportunity to hit him over the head, yet again.

"You are already aware of the environmental damage caused by animal agriculture, and you recently stated that you are reducing your meat consumption," writes PETA Prez Ingrid Newkirk.

"This is a small but important step. Now that you're single again and presumably considering dating, you may also be looking for a way to slim down. May we recommend kicking the meat and milk habit entirely and going vegan, which is not only one of the best ways to fight climate change but is also one of the best ways to shed unwanted pounds?"

"If you would like," she adds, "we will send you a gift basket full of delicious vegan foods to help you on the road to a healthier planet and a rekindled love life."
