Prefab Greenhouse + Ardunio Controls = Automated Agriculture (Video)
Sam Bagot and Will Bratton operate Horto Domi (hortodomi.com), an agricultural project they describe as "beyond organic." They're working with small prefab greenhouses, adding sensors and Arduino-actuated controls, and even including an earthworm breeding area in most domes, because earthworms are good for the soil and can increase plant production. If you're the kind of person whose plants always seem to shrivel up and die, this may be a great way to garden. With watering and other functions automated, it looks like all you have to do is set your controls, plant what you want to grow, and wait for the "time to harvest" alarm to go off. Okay, it might not be that simple, but Sam and Will say their gardening method saves a lot of energy and time. It also looks like fun, besides being an easy way to grow your own 100% organic fruits and vegetables.

Silent Running
I have a "gut" instinct that as long as humans are alive (yes, if we find a way to leave our bodies behind this isn't true), flora will survive....
come to think of it those 2 guys look like a couple of pot heads. Think I'm starting to understand their objective with this project.
So why don't you put something together, with your non-Arduino knowledge, that automates the old man screaming at the kids to "Get off my lawn".
