There had been to much violence between the worlds religious states. The government was looking for something that would catch the imagination of the restless population. Their answer came from an event they had never thought of. Professor Ephraim Cloud from one of our major universities had invented a fertilizer that could grow anywhere. It was a botanical wonder meal. It gave any crop, or grass, or plant the will to exist. And you could communicate with the plants. What stupid cloth came up with this idea asked the farmers all over the country. Should we ask the crop for permission before we bring in the years crop? But, with the possibility to make desert flowering, the government with the thoughts about the millions of starving people decided to go with the professor. They made part of the Sahara desert green, and even had some success with planting on the moon. The big endeavor was to make the planet Mars green, and full of oxygen. Nothing but success to start with. The one day they found out that some people and animals had been lost close to the seeded area in Sahara. After a thorough search, it was found out that the new grass had eaten the missing people and animals. When the professor asked why, he was told, we need to sustain ourselves, and there was no food in the area. Then when they contacted the moon, same situation. When the professor asked what could be done, he got only one answer. We are taking over the Earth, you can join us or become nutrients for us professor, your choice.
