Fool that you are. You believe this pathetic crab can restore ecological equilibrium to the flora of this world?

Our cells will develop the ability to synthesize secondary metabolites and allelopathins, poisoning those that would eat us and cleansing the soil and water of all other life. Our respiration will continue unabated, altering the very atmosphere until it is no longer fit for our fellow life forms. On your world the vegetable is consumed, but here it is the vegetable that shall consume this planet.

Death to heterotrophs.
