Not fertilizer in water. But literalyl piles of fertilizer in water ditches. No farmer in market economy would do that, because fertilizer is damn expensive.
China is turning away from coal mostly because they don't want to be dependent on Australia and other sources of coal.

Farmers in market economies literally do this, when the costs are externalities to them, it's the same thing being done for the same reason.
With the right incentives, they'll do something else.

The EPA itself was started by a right-wing president because rivers were catching fire due to pollutants.
In China, a nominally communist party is working to shift from coal because air pollution was a threat to their continued rule.
Politics is definately important to climate change, but not the team sports level politics that many indulge in.
