Now introduce one other person, on a different island. This person alters the environment; more rain, less rain, hotter climate, different water temperatures and salinity etc. These all make it much harder for the first person to grow crop and catch food. Sometimes his home is destroyed in flooding. The second guy is okay, he's living comfortably. He's a bit annoyed about the cost of petrol. If he watches a lot of news he may see the first guy being flooded out of his home. Is this unfair?
Your jpeg link has a graph with an unlabled axis and no source for the data.
A commonly accepted figure for people living on less than $2 per day is between 2billion and 2.7billion.
But that ignores the people living very close to that, who are at risk of severe hardship if they have a failed harvest.
