To sustainably develop space, we must manage orbital capacity

Once upon a time, we thought that our actions were too insignificant to impact something as large as the natural environment — that it wouldn’t be possible for fishermen to exhaust a fishery, that groundwater was so plentiful that conservation was unnecessary, and that the sky was big enough that the odds of two human-created objects colliding in space, much less threatening our ability to make use of orbits, was negligible. Today we know better. But the road from recognizing a resource as finite to managing it in a sustainable manner is long. More
