Putting aside questions of ecosystems etc, I think the main reason is that we just can’t - ironic since we seem to be extint-ing all the other animals
In South America they tried in the 50s and 60s, and more kept cropping up. They breed so quickly, if you miss an area they can just rebound. Then more can come in on ships and stuff
So you couldn’t really localise it, it would have to be a huge global undertaking. And it would likely require widespread use of pesticides that are at best tricksy and at worst illegal, not to mention environmentally shitty
I don’t think that tracks.
The highest turnout in any US election since 1908 was 62% in 2020, and at no point has a party won an election and been like ‘look at all the people who didn’t vote, I guess we don’t have a mandate to govern’
Parties win elections and govern in power with less than 50% of voters backing them all the time, it’s literally the standard. A low turnout will not change the way any party acts once in power.
