See here how researchers are using evolutionary algorithms to improve the efficiency of photosynthesis process and augmenting the plant productivity without the necessity to apply extra fertilizers.
From the original article:
"Using “evolutionary algorithms,” which mimic evolution by selecting for desirable traits, the model hunted for enzymes that – if increased – would enhance plant productivity. If higher concentrations of an enzyme relative to others improved photosynthetic efficiency, the model used the results of that experiment as a parent for the next generation of tests."
It is the optimization of a process which has been optimized since last 3.4 billion years!
