Asteroid mining might provide a lot of jobs and new sources of gold, titanium, platinum and other metals, as well as hydrogen and ammonia in the future. But it could also spell disaster for telecom satellites orbiting the Earth if it's not managed properly. You see, some companies planning to mine the celestial objects are looking for ways to ferry them closer to home. Remember how NASA aims to take a chunk from an asteroid and drag it to the moon's orbit using a spacecraft? Something like that, but likely on a much bigger scale. Unfortunately, asteroids have weak gravity and could yield huge amounts of debris, which might end up polluting the geosynchronous orbit. That's where most telecom and defense satellites are stationed.
