Yes, because the "charge forward and worry about the consequences later" mantra has proven so historically successful over the past 100 years when it comes to environmental stewardship. CFC's, HFC's, PFAS, leaded fuel, and abundant plastic waste are proof we definitely know what we're doing when it comes to ensuring we don't pollute our planet or ourselves, right? The science on this remains novel precisely because the idea of launching hundreds of rockets a day was inconceivable even 10 years ago.
