Put enough farmers out of business and you’ll cut food production, perhaps enough to trigger a famine. From Doug Casey at internationalman.com:

International Man: Recently, we have seen governments in the Netherlands, and Canada move to shut down farms under the pretext of climate change.
According to John Kerry, Biden’s “climate czar,” similar moves against US farms are in the works.
The US and the Netherlands are two of the largest agricultural producers in the world.
It seems certain Western countries are waging war against farmers in the name of climate change.
What is really going on here?
Doug Casey: I hate to say that things like COVID or a rabid belief in anthropogenic climate change are parts of a conspiracy—although it often seems that way. I tend to discount conspiracies for a number of reasons. It seems more likely they’re mass hysterias—the type of thing that happened in Salem at the end of the 17th century, except on a gigantic scale. Versions of the kind of “group think” that captured a number of countries in the 20th century, as well.
In any event, what appears to be a war against agriculture on the part of “the elite” is both real and serious. People in power are anxious to control every aspect of the plebs’ lives, usually either for the supposed good of humanity or the planet itself. They believe there should be rules governing where the plebs live, what they can say and think, and even what they eat. The “elite” like to say farm animals are partly responsible for global warming by emitting methane.
