Though let us consider the ch-ch-ch-ch-changes that would actually be necessary for each of these to exercise real choice in the matter at hand:
The Public: Die, because that is the only thing that doesn't actively destroy the biosphere, because you have no actual meaningful control over anything
Farmers: Change professions, likely losing everything (at which point they become "The Public"), because you can't even control what seeds you buy (See: Agricorps), let alone anything else you do with the land, and it's all a monopsony, anyway (See: Agricorps) so you can't even choose who buys your crops or for how much you sell them.
Government: Literally the only thing required here is to take a long view and invest in infrastructure that also has huge short-term benefits. Realistically, the actual reason is because the politicians get money from the corpocrats (See: Agricorps), and don't want to not get money from the corpocrats.
Agricorps: It is explicitly against their fiduciary duty to tank the value of long-term investment in their own business by making the planet uninhabitable. The only change required is to actually hold to fiduciary duty, rather than "number go up, STONKS".
Huh, it's almost as if there are very specific problems that can be traced to a single, specific spiderman here... interesting.
