The expert opinions that come from the same people who don't want it to happen? How much are those worth?
To whine and screech "that's too dangerous, don't do that" when other people were proposing solutions. These are the same people who are touted as the experts, mind you. This means that when journalists and talking heads and other jackasses say "but the experts don't even think those things will work", they are talking about the same people who claim that there is an emergency in the first place.
They aren't interested in potential solutions. It's just an attempt to wrestle political power away from those who currently have it and implement economy-murdering policy because they're mad poor people eat meat.
