How long would it take by harvesting algae on a large scale then?
I do not know. However:
We have no simple method of harvesting ocean algae, whereas people
have been harvesting trees for thousands of years. (It would be
simple to harvest algae from ponds or tanks on land.)
Growing trees brings many other benefits, besides fixing the global
warming problem. For example, it prevents erosion and helps to feed
people and wildlife. I doubt there are many benefits to growing
algae. Even if you can develop a method of harvesting it to use it as
fuel the energy overhead would be large. I doubt many people or farm
animals would want to eat the stuff.
