all these mechanical parts will cause pollution both in their production and their disposal.

365 days of production will also require some heavy fertilization cycles, so more chemicals to be produced and disposed.

I don't see that talked much and might very well come ahead with the efficiency of scale in having all these thing stacked instead of dispersed over a large tract of land, but these thing are an important aspect and hopefully what will come out of this deployment is some hard data about the impact they have.
