I don't think blocking out the sun is the answer to global warming lol

Having lived through 3 partial/total solar eclipses, even a small shift in the amount of light really fucks with the rhythm of the entire environment. Birds stopped chirping entirely at noon last time. We'd just be replacing one form of global disaster with another.

Not to mention we'd end up fully saturating the available orbital space around earth, causing constant satellite crashes and the complete inability to launch rockets through the mesh and debris. At a certain point the satellites would cease to function entirely through all the trash orbiting earth and at that point we'd have essentially walled ourselves off from ever safely exploring space. It's a terrible idea all around
