Killing yourself reduces your impact on the Earth by 100% - that doesn't mean it is a productive thing to do. Individual action isn't going to fix this. Each person's contribution is too small. Systemic change is the only way to address this.

Modern industrialized agriculture has a lot of issues. Other methods of agriculture can have net-negative emissions: grow all of your feedstock onsite and use waste products to produce more feedstock. If all the carbon you emit was previously captured onsite, you're only 'borrowing' carbon, not really producing it. Slightly net-negative carbon as soil is built as a byproduct.

I think writing articles about how "You, individual, can do something to save the Earth" is ineffective moralizing not unlike Facebook posts asking to "Share this if you want to end human trafficking!" - the only tangible effect is self-promotion of the author and inflating the self-esteem of the readers who go along with it.
