I am in the process of building a world where all animals suddenly die and only four types of creatures survive on planet Earth: humans, (green) plants, bacteria and fungi.
I am interested in knowing how this would change the world. Specifically, the economic and cultural implications. Of course the impact would be extremely severe as animals are a vital part of our environments.
Would humanity survive this blow? (Death of all farm animals and fish would mean a lot of food would be destroyed along with creating billions of dollars in loss). Would there be enough vegetables to feed the whole population?
How severe would be the shock factor? Also, how would human culture and values change, both immediately and in the long run?
