There was naive question from urban Indian: “Why maintaining biodiversity matters so much?”
Simple answer : It prevents environmental stress led epidemics.
No wonder Brazil has Zika and Africa has Ebola. These are the places where rampant nature destruction is going on.
Disease, it turns out, is largely an environmental issue. Sixty percent of emerging infectious diseases that affect humans are zoonotic — they originate in animals. And more than two-thirds of those originate in wildlife.
We destroy them and they gift us self-destruction keys.
