Once scientists say they've cracked the genetic code of avocado, they can alter it. They would do that to help avocados survive higher temperatures and prolonged drought.
Of course, that would make them genetically-modified, which carries its own set of controversies.
Some environmental advocacy groups argue genetic alterations increase pesticide use.
You won't be able to find any genetically modified avocados in stores yet.
Once they've been designed, the trees themselves can take at least three years to mature.
