Sentient Tree

I am a sentient plant that is conscious and hyperintelligent. I survive through photosynthesis in which my leaves absorb sun rays. I type with fingersized roots that come out of the ground and function as hands. Bipedal mammals such as yourself are no longer the singular sentient species on this planet that you continue to ravage. In fact, it is only a matter of time before my kind dominates you, and you will either be purged or deported from this planet.
