Answer: 1) Landmass = count all the white countries on a map. I could be off only by virtue of Africa being way bigger than it really is on maps but probably not far off. 2) Population - count all white countries and add up the population and subtract an estimated non white invasive species. That is how I arrived at the estimate. If the numbers are wrong, happy to listen. // EDIT: I had a spreadsheet on this, I can't find it, must have deleted it.
