Essay / The role of insects in the web of life - 2579
When asked the question “what are insects for?” many people have nothing positive to say, because they only remember the bad things insects do; bees and wasps sting, ants enter homes, and cobwebs hurt the eyes. However, people tend to forget that insects can do so many good things for the environment in which they live. This includes pollinating flowers and other plants, decomposing plant and animal debris, controlling pest insect populations, and much more. A constant lesson that needs to be reinforced every day so that everyone understands that not all bugs are bad and that many bugs do more than expected. When Gilbert Waldbauer was asked the same question: “what are bugs for?” he wrote a book to give his best answer and titled the book What Are Insects Good For? – Insects in the web of life. In his book, he addresses four main areas: helping plants, helping animals, limiting population growth, and cleaning up. Within these four main areas, there are twelve different topics; all of which cover a broad spectrum of how bugs bring good. Among the topics Waldbauer covers, the most important way insects bring good to different environments is by helping plants and flowers through pollination and seed dispersal. Today, pollination is a common everyday occurrence and no one thinks twice about how and why it happens. However, two centuries ago, very few people understood insect pollination, as showy flower petals were said to be the Creator's means of pleasing his people (Waldbauer, 2003). It was not until 1793 that Conrad Sprengel first explained that colorful flowers are a means of attracting insects for pollination (Waldbauer, 2003).
