Your meat-free day
For 24 hours, you are to avoid all meat.
No ham for breakfast, not chicken filé for lunch, no meatballs for dinner. Fish, eggs, black pudding are ok during this mission. They don't count as meat.
About 15% of all green house effect in the world comes from meat production. [https://en.wikipedia.org/wiki/Environmental_impact_of_meat_production]
