That's not taking it nearly far enough. Our distant ancestors were very adept at destroying ecosystems and causing extinctions with only flint and spears. They massively disrupted every environment they explored. If we want to live non-destructively, we should ban even the use of fire and sharp sticks. In one way of looking at it, all technology, even the most primitive, is sufficient for destruction. From another point of view, the tool itself is not the real problem.
