Is it possible to genetically engineer fast-growing but sterile trees that are 5x the height and width of mature hardwoods? Plant one in every sizeable park, greenbelt, and plaza. Would add some nice green variety to skylines and suburbs and make for comfortable shade for much of the surrounding area and trails. The only downside is liability and danger of falling limbs, especially during storms.


I know nothing about this but typically fast growing trees are less sturdy (they shed a lot of branches) and short-lived.


I doubt it.

Where would these enormous fast-growing trees get their hefty nutrient requirements from?


Specifically, the partial pressure of carbon dioxide.

"the efficiency of photosynthesis ... is usually below 1%, ... However, plants are efficient in using CO2 at atmospheric concentrations,"

This engineered tree would have to pump CO2 into itself.


Nutrients are largely material that plants draw from the earth, not atmospheric gasses.


I figured that's a detail, when the goal is to remove CO2 from the atmosphere.
