Any cutoff between use and overuse is artificial. It is still use. If it is use, and if it is with billions of people, one day, some resources will be consumed. Maybe sooner, maybe later, but on million-years-scale, it doesn't make any sense anyway.
Overheating, oversheltering, both seems very artificial to me. Ok, you can have a wood cabin in forests, but what's next? Are antibiotics use or overuse? Is internet use or overuse? And who is supposed to decide? Using nonrenevables/using renevables is nice in a thing it is black/white, it has no value component in it.
I don't know how removing interest could help except making some operations nonviable. Without interest, all ventures would have to use different sources of financing. I think a demand for risky lending (where risk is compensated in a form of interest) is natural and would exist in some way anyway.
