Not enough cooking oil in the world to support this crazy idea. We need to embrace climate change. Look at California getting all that rain once again, setting records! Awesome. The stupid actions taken by liberals is like 2 of us going to the beach and taking a cup of water from the ocean to counteract them from rising.
