Replication of results is key to determining if something is true or not. What sense does it make to force massive expensive changes based on studies that have often proven to not be replicable. There is a replication crisis in science where a massive number of published studies have results that cannot be verified by other researchers. Just because many/most scientists believe something does not make it necessarily true. Most scientists only know what they read in journals about subjects they do not personally study. (from Wikipedia) "According to a 2016 poll of 1,500 scientists reported in the journal Nature, 70% of them failed to reproduce another scientist's experiments (50% failed to reproduce their own experiment). These numbers differ among disciplines:chemistry: 90% (60%),biology: 80% (60%), physics and engineering: 70% (50%),medicine: 70% (60%),Earth and environment science: 60% (40%)". When half the people cannot reproduce their own results something is very wrong. We need to take a step back to understand and verify so we know whats really true before we make decisions that will need to be implemented by force which is what we do for all laws.
