Sometimes we humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself is a perfect example of that—no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase the overall global temperature and risk millions of people’s lives and livelihoods, let alone the impact it would have on the species we share the world with. According to a new release from the Salata Institute at Harvard, we seem to be going down the same blind path with a different engineering challenge in this century—satellite megaconstellations.
