Here's another one that isn't going to win any subtlety awards, but has obviously been drawn to make a very pressing point about the world we live in. As with many of this artist's drawings, there's more than one way you could look at this, and no single correct interpretation.
On one hand, we have a couple minding their own business and enjoying their time, being approached by far more people in the water than could ever fit on their boat. If they all get on board, everybody's going to sink. On the other hand, you could see it as two very indulgent people living a life of luxury and paying barely any attention to the fact that there could be people drowning around them. If they give away the land they sit on, everybody drowns. If they do nothing, some people drown. Is there a happy medium? That's a question we're still wrestling with as a species.
