@WoodshopHandman @boeswilligkeit Limited resources, limited heat dissipation capacity, constant threat of rocks falling and everyone dying. Do we want to destroy the world God gave us? Do we want to let all of God's creation be destroyed? What level of quality of life is acceptable on Earth? Should we prevent all humans from breeding or cull people by some arbitrary means to keep numbers at some very low level?

If we want to survive and thrive, we need space colonies. Space, mind you, not planets.
