Later this year Reflect Orbital will launch a test satellite, the test is to use giant mylar mirrors to reflect sunlight back to earth, their excuse is to target it mainly at solar farms so that they can make money.
If all goes well the plan is to launch 50,000 of them within the next ten years.

This will very badly mess up the natural sleep patterns of humans, wildlife and even plants (the latter need some hours of darkness too, believe it or not).
So that's potentially yet more night sky pollution, and that's on top of the pending hundreds of thousands of comms and data centre satellites which various nations are planning to launch within the next few years, so increasing night sky pollution with their many points of light (which will be visible in formations within an hour or two of dawn and dusk). Those hundreds of thousands of points of light will outnumber those visible stars that can be seen from any point on earth when the sky is clear.
Is nothing sacred any more?
Why are the small proportion of exceptionally greedy and stupid humans allowed to make even more of a mess of the planet for the rest of us as well as the planet's other inhabitants?
