Robotic Plants

I was thinking about the environment today. And how we need plants to convert Carbon Dioxide back into Oxygen for us to breathe and also so we can burn stuff. But. What if robots wanted to take over by destroying all the plant life on Earth. For what that might be like, watch this:




Back to the point. Robots try to kill all our plants, til there's only a couple left that a human rebel force must defend to save the race. That's the theme of Save the Last Plants, a sweet sci-fi short story I'm going to write. Maybe.

But really, why can't we make some sort of machine that converts CO2 to O2? We just need to get rid of that stupid Carbon, and plants can do it, and we're like a billion times smarter than plants. Admittedly, I know next to nothing about chemistry, but i'm sure some people do, and there shoud be a way to figure this out. Think about it. We could just cut down the whole rainforest and replace it with a sweet metropolis of solar-powered robotic trees. How ill would that be?! And for all you tree-huggers out there, I have this little nugget of wisdom for you to chew on: no matter how many trees we cut down, there will always be an environment.

So there.
