      But there are a ton of species out there that are crucial to even our own survival, or else we would go through some dark times like our economy would plummet because of increase in prices of food because of scarcity in supply of food. Or perhaps the quality of the food we have becomes affected and may even cause new health issues. Or more people become hungry which could lead to increase in violence and revolt, etc.
