So where's the "ecological" part? There is no ecology to wreck. There are concerns about the metallic dust from burning up on reentry, but no mention of it in this article.
Humans are organisms. Humans go to space, and will go there more with it getting cheaper. Orbital space is an environment. Debris collisions are an ecological concern for spacefaring organisms.
Less snark: I think definition (or more accurately, your expansive interpretation of it) misses the spirit of the way that word is generally used.
Not to mention all the communications systems we have in orbit that we rely on for our economy which would result in significant loss of logistics / economic efficiencies and straining growing social political issues. All of which means higher likelihood of damage to local and regional ecologies
