Volcano in Iceland
Last year, a volcano in Iceland erupted, and that eruption interfered with air travel for many parts of the world. This year, another volcano http://www.herald.ie/breaking-news/world-news/iceland-volcano-wont-cause-chaos-2654462.html is erupting, and the concerns are present that the same problems will occur.
Well, that may be true. But no one controls those volcanoes and their eruptions.. As human beings we sometimes seem to act and think as if we control the universe and the natural events on the Earth. But we occasionally or repetitively and consistently need a come-uppance to remind us that we do not control nature, and we need to learn to prepare, adapt, and otherwise be flexible about the adversities that weather heaps on us.
