I'm sorry, but most of that is nonsense (besides oxides being tough to break). Where is this "elsewhere" you're planning to grow food for the /world population/

I'm sorry, but most of that is nonsense (besides oxides being tough to break). Where is this "elsewhere" you're planning to grow food for the /world population/? Protecting people from heat is one thing but what about animals that most people depend on for survival? Fremen suits for them as well? What about bees, birds and the myriad living things that we are only dimly aware of yet utterly depend on and that are adapted to live only under certain conditions? People will have to change their behavior to survive collectively. Technology is part of the solution (renewable energy, zoom calls instead of business travel...) but the idea that everyone needs a car that just sits around idly 95% of the time is ludicrous. If humanity is to survive, this sort of widespread ludicrous and unsustainable behavior needs to stop... I'm sorry if I come across a bit harsh but your comment sounds quite defeatist. If you need an argument mir grounded in economics, have a look at the relative price of coal power: even ignoring the health and climate effects, it's getting too expensive compared to renewables (lots of asterisks on that one but the gist is true).
