Well, from a practical perspective, with advanced space travel and space mining and manufacturing abilities we can produce solar shades to counter global warming.
I think there are a few reasons you're getting downvotes, but they're involved enough that few are going to spare the effort to explain.
For example, all three of your last sentences are going to be strongly disagreed with and some people are going to read both a lack of thought on your part and a flawed way of thinking (ie. In terms of narrative, memes, drama) into those sentences and will decide it's not worth trying to engage and instead will just try and get rid of your message/you.
And I'm sure with advance study and research we could collect oil out of the polluted seas, digest litter. We didn't need solar shades 50 years ago. Why are we needing them now?
And just because we need them now doesn't make fair reason to space ventures.
Excluding the childish editorial remarks I made, the questions in which I pointed out are serious and are all pressing issues we currently face.
If they can be involved on clicking on a down arrow, they should be able to invest in to why they are clicking the down arrow. There was no attempt to fuel drama.
