The End of the World: a Pea-Shooter at the Beginning, There Is Never Enough Sunshine

The end of the world is coming? As long as there is sunshine, I can grow anything! Lack of water and food? Plant [Sunflower] to produce unlimited sunlight, and you can eat all the plants you plant. Dead Rising? Plant two rows of [Torch Stumps] + [Gatling Pea] at the door, and burn as many as you like. That is my fertilizer!
