Do the math: how deep is the atmosphere, and how much of it does wind power generation affect? Most likely substantially less than skyscrapers alone, let alone the rest of cities.

yes, someone should in fact do the math!

e.g. I vaguely remember some factoid about how some significant amount of top-soil in the Amazon rain forest is attributed to top-soil/sand from Africa? Also, I just googled "deforestation affect wind" and got some interesting results.

Trillions of tree's blowing in the wind hasn't seemed to cause much issue.

so we need wind harvester's which approximate trees? then we can chop down some existing trees in windy spots and drop those in?

otherwise, we need a bit more study..

I think you misunderstood my comment. The original comment was asking about the concern of wind turbines stopping the wind and what affect that would have on the environment. I was pointing out the fact that tree's currently do the same thing, only we have trillions of tree's compared to thousands of turbines.
