If everyone in the united states were willing to pay as much extra per pound for shade-grown coffee as you are, how much additional money would that provide for conservation of biodiversity in the tropics each year?

Well the USA spends about $40 billions dollars on coffee right? In 2017 it was determined 67% of Americans drink coffee. I don’t know how much you pay for shade grown coffee. It seems more expensive. But if you were to do it this way it would protect and persevere many animals and birds in tropical areas! (Shade grown coffee is grown under a canopy of trees) I hope I helped!

The answer is ozone layer.
