Butterfly Lessons

Butterfly Lessons

The title of the article is slightly misleading, one might think that you are about to read about the life of a butterfly, which to me is a carefree, happy life. Wrong. This article dipicts the challenges insects and toads are facing due global warming. Climate changes are forcing migration, which for some insects and toads is easy, yet for some plants this change is causing them to face extinction.

To me, the most alarming part of this article was not about how insects and toads are migrating, but it is a small paragraph at the end of the article (which most people who dont make it through the nine pages about insect migration wont ever see) that seems to serve as a warning. "Ultimately, all of the crops we grow are biological species; all the diseases we have are biological species; all the disease vectors are biological species. If there is this overwhelming evidence that species are changing their distributions, we're going to have to expect exactly the same for crops and pests and diseases. Part of it simply is we've got one planet, and we are heading it in a direction in which, quite fundamentally, we don't know what the consequences are going to be." After taking a minute to consider what this small paragraph means, I realized that this carries some serious weight. This is not something we want to allow to continue to happen, we are not ready for diseases and pests to change. If the ecosystem is suffering now, imagine what will happen once diseases and pests change and start attacking.
