Butterfly Lessons

Kolber talks about how human actions are having a huge affect on the the environment and the species that live in it.  She claims that humans are causing climate change and this is disrupting the life of many species around the world.  She does not believe these changes should be happening this quickly and believes that humans deserve all the blame.  At one point Kolber writes, "Darwin never imagined that the effects of climate change could be observed in a human lifetime, yet, almost anywhere you go in the world today, it is possible to observe changes".  These changes are being observed rapidly.  At one point she talks about how some toads are beginning to mate ten days earlier and how some species are moving further up mountains where it is cooler.  The article gets its name because she explains how butterflies are shifting north in Europe to areas where it is cooler.  Bottom line, Kolber is trying to say that humans are causing climate change and this is affecting the environment all over the world.
