We could for example lower taxes for those that earn least while increasing water and soil quality regulations (with matching tariffs for imports). This would increase food costs, which would hopefully match the money that people gained through lower taxes.

Meat would then become slightly more expensive than plant, but also have a major benefit for products that don't use a lot of water or harms the soil. Aquaculture would get a big boost, as would alternative method of meat production. The use of farm animals as an ecological alternative to using machinery to keep land clear of unwanted vegetation has become a niche method, and increased water and soil regulations would indirect benefit such farming alternatives.
