Uuffff.. I get it where the article is trying to go, but "..the pigs exist a little too much."

Well, we rape nature, we unbalance natural order and when there are 50-100 more pigs we need to slaughter them.

In cases like that what comes to mind is the Hubris, Atis, Nemesis, Tisis. (https://www.greecehighdefinition.com/blog/hubris-atis-nemesi...).

We (humans) 'contaminated' the island with pigs and other animals and we were a-ok while they were ravaging other species. Now they are annoying us we need to take swift and firm action and eliminate them.

I am looking forward to a future where the cities will be under a self-sustainable 'dome' and everything between those cities will be wilderness/jungle, we will let nature take over.
