This is so profoundly sad for a country that once had so much. My Cuban ex-pat family decry the communist government role here but I can never forgive the US for their inhumanity in tacitly letting this disaster unfold and others in the Caribbean, but what else is new.
As a geologist I will retort that if Minecraft environments had eroding surfaces like real life does then that bedrock would also be visible at the surface. Outcrops are just areas that are experiencing erosion rates faster than areas that are overlayed with soil. That said, there are a cool Minecraft programs for geological processes that have been shown to be educational.
